Technical Data and Specifications
Frequency
Eaton standard dry-type
distribution transformers are
designed for 60 Hz operation.
Transformers required for
other frequencies are
available and must be
specifically designed.
Overload Capability
Short-term overload is
designed into transformers as
required by ANSI. Dry-type
distribution transformers will
deliver 200% nameplate load
for one-half hour, 150% load
for one hour and 125% load
for four hours without being
damaged, provided that a
constant 50% load precedes
and follows the overload.
See ANSI C57.96-01.250 for
additional limitations.
Continuous overload capacity
is not deliberately designed
into a transformer because
the design objective is to be
within the allowed winding
temperature rise with
nameplate loading.
Insulation System and
Temperature Rise
Industry standards classify
insulation systems and rise as
shown below:
Insulation System
Classification
The design life of transformers
having different insulation
systems is the same—the
lower-temperature systems
are designed for the same life
as the higher-temperature
systems.
Enclosures
Eaton’s ventilated
transformers, Types DS-3 and
DT-3, use a NEMA 2 rated
(drip-proof) enclosure as
standard, and are rated
NEMA 3R with the addition
of weathershields.
Winding Terminations
Primary and secondary
windings are terminated
in the wiring compartment.
Encapsulated units have
copper leads or stabs
brought out for connections.
Ventilated transformers have
leads brought out to terminals
that are pre-drilled to accept
Cu/Al lugs. Aluminum-wound
transformers have aluminum
terminals; copper-wound
models have copper
terminals. Lugs are not
supplied with these
transformers. Eaton
recommends external cables
be rated 90°C (sized at 75°C
ampacity) for encapsulated
designs and 75°C for
ventilated designs.
Series-Multiple Windings
Series-multiple windings
consist of two similar coils in
each winding that can be
connected in series or parallel
(multiple). Transformers with
series-multiple windings are
designated with an “x” or
“/” between the voltage
ratings, such as voltages of
“120/240” or “240 x 480.”
If the series-multiple winding
is designated by an “x,” the
winding can be connected
only for a series or parallel.
With the “/” designation,
a mid-point also becomes
available in addition to the
series or parallel connection.
As an example, a 120 x 240
winding can be connected
for either 120 (parallel) or
240 (series), but a 120/240
winding can be connected for
120 (parallel), or 240 (series),
or 240 with a 120 mid-point.
For additional information,
please refer to Section 2.7
Page V2-T2-191.

Sound Levels
All Eaton 600 volt class
general-purpose dry-type
distribution transformers are
designed to meet NEMA
ST-20 sound levels listed
here. These are the sound
levels measured in a
soundproof environment.
Actual sound levels
measured at an installation
will likely be higher (as much
as 15 dB greater) due to
electrical connections and
environmental conditions.
Lower sound levels are
available and should be
specified when the
transformer is going to be
installed in an area where
sound may be a concern.

NEMA TP-1 Energy-Efficient Transformers
K-Factor
Product Description
A common industry term for
the amount of harmonics
produced by a given load is
the K-factor. The larger the
K-factor, the more harmonics
are present. Linear loads, for
example, have a K-factor of 1.
Transformers may carry a
K-factor rating to define the
transformer’s ability to
withstand the additional
heating generated by
harmonic currents.
Calculating the K-Factor
All nonlinear waveforms
can be broken down
mathematically into a
fundamental frequency
and its harmonics. IEEE
C57.110 establishes a direct
relationship between these
harmonics and transformer
heating. Underwriters
Laboratories has established
a similar relationship, the
K-factor, which is derived by
summing the square of the
percentage current at a
given harmonic level
multiplied by the square
of the harmonic order.
K = ²(Ih)2(h)2
Ih = Percent Current at
Harmonic h
h = Harmonic Order,
i.e., 3rd, 5th, 7th
For example, a load that is
90% of the fundamental,
30% of the third harmonic,
and 20% of the fifth harmonic
would yield (.9)2(1)2 + (.3)2(3)2
+ (.2)2(5)2 or a K-factor of
2.62. This load would require
an Eaton KT-4 transformer
with a K-factor rating of 4.
Transformers that carry a
K-factor rating define the
transformer’s ability to
withstand a given harmonic
load while operating within
the transformer’s insulation
class.
An analysis of harmonic loads
and a calculation of the
K-factor must be made to
properly apply transformers
in any building or facility.
Note that the calculated
K-factor is not constant
because nonlinear loads
change throughout the day
as equipment and lighting is
turned off and on. These
harmonic loads also change
over the life of the building or
facility as equipment is added
or removed.
Harmonic Currents
Harmonic currents are found
in nonlinear loads. These
currents are generated by
various types of equipment
including switching mode
power supplies that abruptly
switch current on and off
during each line cycle.
Switching mode power
supplies or diode-capacitor
power supplies convert
AC line voltage to low
voltage DC. This process
is accomplished by charging
capacitors during each line
cycle with narrow pluses
of current that are time-
coincident with line voltage
peaks. Examples of this
equipment include electronic
ballasts for fluorescent
lighting, personal computers,
printers, fax machines,
electronic and medical test
equipment, uninterruptible
power supplies, and
solid-state motor drives.
Note: Nonlinear is synonymous
with the term non-sinusoidal.
Harmonic Currents Found in Nonlinear Loads Cause Wave
Shape Distortion and Create Added Stresses on Transformers

Accessories
Please refer to Section 2.7 Page V2-T2-191.
Technical Data and Specifications
Frequency
Eaton standard dry-type
distribution transformers are
designed for 60 Hz operation.
Transformers required for
other frequencies are available
and must be specifically
designed.
Overload Capability
Short-term overload is
designed into transformers
as required by ANSI. Dry-type
distribution transformers will
deliver 200% nameplate load
for one-half hour, 150% load
for one hour, and 125% load
for four hours without being
damaged, provided that a
constant 50% load precedes
and follows the overload.
See ANSI C57.96-01.250 for
additional limitations.
Continuous overload capacity
is not deliberately designed
into a transformer because
the design objective is to be
within the allowed winding
temperature rise with
nameplate loading.
Insulation System and
Temperature Rise
Industry standards classify
insulation systems and rise as
shown below:
Insulation System
Classification
The design life of transformers
having different insulation
systems is the same—the
lower-temperature systems
are designed for the same life
as the higher-temperature
systems.
Enclosures
Eaton ventilated transformers,
Type KT, use a NEMA 2 rated
(drip-proof) enclosure as
standard, and are rated
NEMA 3R with the addition
of weathershields.
Winding Terminations
Primary and secondary
windings are terminated in
the wiring compartment.
Ventilated transformers
have leads brought out to
aluminum pads that are pre-
drilled to accept Cu/Al lugs.
Lugs are not supplied with
these transformers. Eaton
recommends that external
cables be rated 75°C for
ventilated designs.

Sound Levels
All Eaton 600 volt class
general-purpose dry-type
distribution transformers are
designed to meet NEMA
ST-20 sound levels listed
here. These are the sound
levels measured in a
soundproof environment.
Actual sound levels
measured at an installation
will likely be higher due to
electrical connections and
environmental conditions.
Lower sound levels are
available and should be
specified when the
transformer is going to be
installed in an area where
sound may be a concern.
For additional information,
please refer to Section 2.7
Page V2-T2-195.

Product Description
Note: The following pages
provide listings for most standard
transformer ratings and catalog
numbers. For other ratings or
catalog numbers not shown,
or for special enclosure types
(including stainless steel), refer
to Eaton.
The electrical transformer
has been a staple of electrical
power systems for the past
100+ years. While the types
of electrical loads that are
being added to our systems
today have radically changed,
the transformer has stayed
relatively the same in
design during this time frame.
Eaton’s harmonic mitigating
transformer (HMT)
represents the evolution
of the transformer into
something that will best
provide clean, energy-
efficient electricity to
power the loads of today
and tomorrow. The recent
shift of our electrical loads
from predominately AC
consumers (resistive heating
elements, incandescent
lighting, three-phase motor
load) to DC consumers (such
as computers, fax machines,
printers, down to the
“wall-wart” that recharges
the cell phone) requires that
our electrical infrastructure
changes as well. These new
loads now introduce other
currents and frequencies
into our electrical power
systems—commonly known
as “harmonics.” Harmonic
currents can cause additional
heating, which may cause
transformers, generators
and conductors to become
overloaded. Excessive heat is
one of the major reasons that
standard transformers and
conductors fail prematurely.
These harmonic currents
have various other effects
(such as “loss of ride-through
capability,” reduced lifespan
and mysterious misoperation
of equipment) on the
components and loads of an
electrical distribution system.
Eaton’s HMTs, when used
properly within an electrical
system, will help keep the
loads operating the way the
manufacturer designed
them and keep the facility’s
electrical system free from
voltage distortion.

●Harmonic mitigating
(cancellation) transformers
are a cost-effective
means of treating harmful
harmonics in an electrical
distribution system
●Reducing harmonic
content in electrical
systems can result in a
more reliable electrical
system, lower
maintenance costs,
less downtime, fewer
equipment malfunctions,
and lower cooling
system capacity

phase-shift configurations
that allow flexibility to
target specific families
of harmonics

Energy-Efficient Harmonic Mitigating Transformers
Accessories
Harmonic mitigating
transformers are available
with the same options and
accessories as general-
purpose ventilated
transformers. Please
refer to Section 2.7
Page V2-T2-191.
Technical Data and Specifications
Frequency
Eaton standard dry-type
distribution transformers are
designed for 60 Hz operation.
Transformers required for
other frequencies are
available and must be
specifically designed.
Overload Capacity
Short-term overload is
designed into transformers as
required by ANSI. Dry-type
distribution transformers will
deliver 200% nameplate load
for one-half hour; 150% load
for one hour and 125% load
for four hours without being
damaged, provided that a
constant 50% load precedes
and follows the overload.
See ANSI C57.96-01.250
for additional limitations.
Continuous overload capacity
is not deliberately designed
into a transformer because
the design objective is to be
within the allowed winding
temperature rise with
nameplate loading.
Insulation System and
Temperature Rise
Industry standards classify
insulation systems and rise as
shown below:
Insulation System
Classification
The design life of transformers
having different insulation
systems is the same—the
lower-temperature systems
are designed for the same life
as the higher-temperature
systems.
Enclosures
Eaton ventilated transformers
Types DS-3 and DT-3 use a
NEMA 2 rated (drip-proof)
enclosure as a standard, and
are rated NEMA 3R with the
addition of weathershields.

Energy-Efficient Harmonic Mitigating Transformers
Demystifying Harmonic Mitigating Transformer Myths
Aren’t “power factor corrected”
computer power supplies fixing
all harmonics?
The use of power factor
corrected computer power
supplies is a great first start
to reducing harmonic currents
in your facility. These are
becoming prevalent in server
applications, but have not
“crossed-over” into the laptop
computer/business computer.
Remember also that, once the
computer power supply
harmonics are addressed,
you will still need to address
the harmonic currents coming
from the variety of other
equipment in your facility.
Don’t K-rated transformers
fix harmonics?
The K-rated transformer
was created to address
the additional heat being
produced by standard delta-
wye transformers when
feeding nonlinear loads.
The goal of the K-rated
transformer is to dissipate the
heat produced over a larger
area, thus providing
the illusion of correction.
The K-rated transformer
does nothing to reduce
the root issue of harmonic
currents or correct power
quality issues. Because of
their larger size, they also
consume additional energy
to “do the same work” and
are counter-productive to an
energy-efficient electrical
distribution design.
Don’t you need two HMTs for
any correction to occur?
The design of HMTs allows
them to address different
families of harmonic currents
in different ways. A single
HMT will treat the triplen
(3rd, 9th, 15th and so on)
harmonic currents in its
secondary winding. The 5th,
7th, 17th and 19th harmonic
family is treated on a system
basis through a technique
known as “phase shifting.”
This phase shift does occur
between the Type NON and
Type THR, and the Type POS
and Type NEG harmonic
mitigating transformers—and
this can also occur between
a Type NON and a standard
delta-wye transformer (that
is probably already existing
within your facility). See our
Sample HMT Applications
area for additional information.
The cost of HMTs is too high!
While the initial cost of HMTs
is typically 1.5 to 4 times the
cost of a standard transformer
(due to the additional design,
materials and labor involved
in creating the magnetics
necessary to reduce harmonic
impact)—to not use an HMT in
a harmonic environment will
actually cost you 250% more
energy loss in the transformer.
Due to the relatively long life of
a transformer (20–30 years),
these additional energy costs
easily overshadow the initial
one-time first cost increment.
If I use one HMT, don’t I need to
change all my transformers?
Most facilities have only a
percentage (typically 20–25%)
of their electrical system that
really requires the use of an
HMT. This means in a typical
building that only a few areas
are either critical (meaning
high requirements for
“clean” power) or have high
concentrations of electronic,
nonlinear loads—requiring
the use of the HMT in those
specific areas. The harmonic
mitigating transformer is a
weapon in your arsenal in
providing a complete, properly
designed electrical system for
today and tomorrow.
Transformer Technology Table Explanation
In understanding the product
placement of the HMT, it
becomes useful to have
some “rule of thumb”
understanding to compare
products. Looking at one of
the aspects of an HMT—
price—you can see that,
if a standard delta-wye
transformer had a cost of
one unit, a K-13 transformer
would cost about double and
an HMT would cost 1.5 to
4 times the unit cost. What’s
impressive to compare is the
next column of information—
”Energy Savings.” If the
amount of energy used to
power today’s loads is
compared against a standard
delta-wye transformer (that
was never designed to feed
today’s types of loads), you
can easily see that the HMT
is designed to meet the issue
head-on! Referring to the
table’s information, you can
see that it would take 30%
more energy to power the
same computer loads with
a K-13 transformer, whereas
an HMT would take 25% less
energy to feed those same
computer loads. (This is due
to the fact that the HMT
has a different design
than a standard delta-wye
transformer and addresses
the root issue of harmonic
currents.) A good analogy is
to look at the incandescent
light bulb versus a compact
fluorescent lamp—you might
pay a bit more up front, but
because of the large energy
savings (because of the
harmonic loading), you soon
realize that the upfront cost
pales in comparison to the
potential of energy saved.
Eaton would be happy
to provide you with an
estimation calculator to
help you determine the
amount of payback and return
on investment (ROI) based
on the incremental cost of
the HMT. It’s very typical to
return the price differential
between the HMT and a
standard transformer with a
few years—thus using the
additional 20 to 30 years of
energy savings to add to your
bottom line.

Energy-Efficient Harmonic Mitigating Transformers
Sample HMT Applications
Typical Application of Type NON Transformer
Installation of a Type NON
transformer provides an
effective treatment of triplen
(3rd, 9th, 15th and so on)
harmonic currents that
are generated by loads
connected to the transformer.
Triplen harmonic currents
are treated in the secondary
windings of the transformer
due to the transformer’s low
zero sequence impedance.
Type NON transformers
do not need to be used in
combination with other
transformers to treat triplen
harmonic currents. A single
Type NON transformer may
be installed, or multiple units
can be applied.
Type NON transformers are
an ideal solution for treating
triplen harmonics generated
by personal computers,
printers, fax machines and
other office equipment,
as well as by single-phase
electronic ballasts, and single-
phase electronic testing or
monitoring devices.

Typical Application of Type NON Transformer
with a Standard Delta-Wye Transformer
When a delta-wye transformer
exists in an electrical
distribution system, the
addition of a Type NON
transformer offers an
economical solution for treating
harmonic currents. The 30°
phase-shift created between a
Type NON harmonic mitigating
transformer and a delta-wye
transformer (standard
transformer or K-Factor
transformer) provides
treatment of 5th, 7th, 17th
and 19th harmonic currents.
These harmonic currents are
canceled in the common
electrical bus that feeds the
transformers. Additionally,
triplen (3rd, 9th, 15th and
so on) harmonic currents
generated by the loads
connected to the Type NON
transformer will be treated
in the secondary windings of
the Type NON transformer
due to its low zero sequence
impedance. When using two
or more transformers to treat
harmonics, it is better that the
load be split equally between
the transformers to receive the
maximum benefit.
Note: Triplen currents will still
circulate in the delta-wye
transformer for additional waste.

Energy-Efficient Harmonic Mitigating Transformers
Optimum Application of Type NON and
Type THR Transformers
When you’re searching for an
optimum harmonic correction
solution in an electrical
distribution system, the
combination of a Type NON
and Type THR transformer
offers a great solution.
The 30° phase shift created
between Type NON and type
THR harmonic mitigating
transformers provides
treatment of 5th, 7th, 17th
and 19th harmonic currents.
These harmonic currents are
canceled in the common
electrical bus that feeds the
transformers. Additionally,
triplen (3rd, 9th, 15th and
so on) harmonic currents
generated by the loads will
be treated in the secondary
windings of HMTs. This will
ensure that these currents
will not circulate in the
primary of the transformer
creating additional heat,
voltage distortion and wasted
energy loss. When using
two or more transformers to
treat harmonics, it is better
that the load be split equally
between the transformers
to receive the
maximum benefit.

Typical Application of Type NEG and

The combination of a Type

transformer and a Type NEG
(–15° phase-shift) transformer
effectively treats 5th, 7th,
17th and 19th harmonic
currents. These harmonic
currents are canceled in the
common electrical bus that
feeds the transformers.
Additionally, triplen (3rd, 9th,
15th and so on) harmonic
currents generated by the
loads connected to these
transformers will be treated in
their secondary windings due
to their low zero sequence
impedance. When using two

General-Purpose Encapsulated Transformers
Accessories
Please refer to Section 2.7 Page V2-T2-191.
Technical Data and Specifications
Frequency
Eaton standard dry-type
distribution transformers are
designed for 60 Hz operation.
Transformers required for
other frequencies are
available and must be
specifically designed.
Overload Capability
Short-term overload is
designed into transformers as
required by ANSI. Dry-type
distribution transformers will
deliver 200% nameplate load
for one-half hour, 150% load
for one hour and 125% load
for four hours without being
damaged, provided that a
constant 50% load precedes
and follows the overload.
See ANSI C57.96-01.250 for
additional limitations.
Continuous overload capacity
is not deliberately designed
into a transformer because
the design objective is to be
within the allowed winding
temperature rise with
nameplate loading.
Insulation System and
Temperature Rise
Industry standards classify
insulation systems and rise as
shown below:
Insulation System
Classification
The design life of transformers
having different insulation
systems is the same—the
lower-temperature systems
are designed for the same life
as the higher-temperature
systems.
Enclosures
Eaton encapsulated
transformers, Types EP and
EPT, use a NEMA 3R rated
enclosure as standard. NEMA
4X enclosures (grade 304 or
316 stainless steel) are
available as an option.
Winding Terminations
Primary and secondary
windings are terminated in
the wiring compartment.
Encapsulated units have
copper leads or stabs
brought out for connections.
Ventilated transformers
have leads brought out to
aluminum pads that are pre-
drilled to accept Cu/Al lugs.
Lugs are not supplied with
these transformers. Eaton
recommends that external
cables be rated 90°C
(sized at 75°C ampacity) for
encapsulated designs and
75°C for ventilated designs.
Series-Multiple Windings
Series-multiple windings
consist of two similar coils
in each winding that can be
connected in series or parallel
(multiple). Transformers with
series-multiple windings are
designated with an “x” or
“/” between the voltage
ratings, such as voltages of
“120/240” or “240 x 480.”
If the series-multiple winding
is designated by an “x,” the
winding can be connected
only for a series or parallel.
With the “/” designation,
a mid-point also becomes
available in addition to the
series or parallel connection.
As an example, a 120 x 240
winding can be connected
for either 120 (parallel) or
240 (series), but a 120/240
winding can be connected for
120 (parallel), 240 (series) or
240 with a 120 mid-point.

Sound Levels
All Eaton 600 volt class
general-purpose dry-type
distribution transformers are
designed to meet NEMA
ST-20 sound levels listed
here. These are the sound
levels measured in a
soundproof environment.
Actual sound levels
measured at an installation
will likely be higher due to
electrical connections and
environmental conditions.
Lower sound levels are
available and should be
specified when the
transformer is going to be
installed in an area where
sound may be a concern.
For additional information,
please refer to Section 2.7
Page V2-T2-195.

Technical Data and Specifications
Frequency
Eaton standard dry-type
distribution transformers are
designed for 60 Hz operation.
Transformers required for
other frequencies are
available and must be
specifically designed.
Overload Capability
Short-term overload is
designed into transformers
as required by ANSI. Dry-type
distribution transformers will
deliver 200% nameplate load
for one-half hour, 150% load
for one hour and 125% load
for four hours without being
damaged, provided that a
constant 50% load precedes
and follows the overload.
See ANSI C57.96-01.250 for
additional limitations.
Continuous overload capacity
is not deliberately designed
into a transformer because
the design objective is to be
within the allowed winding
temperature rise with
nameplate loading.
Insulation System and
Temperature Rise
Industry standards classify
insulation systems and rise as
shown below:
Insulation System
Classification
The design life of transformers
having different insulation
systems is the same—the
lower-temperature systems
are designed for the same life
as the higher-temperature
systems.

40°C 115°C 30°C 185°C
40°C 150°C 30°C 220°C
Enclosures
Eaton ventilated transformers,
Type MD, use a NEMA 2
rated (drip-proof) enclosure
as standard, and are rated
NEMA 3R with the addition
of weathershields.
Winding Terminations
Primary and secondary
windings are terminated in
the wiring compartment.
Ventilated transformers
have leads brought out to
aluminum pads that are pre-
drilled to accept Cu/Al lugs.
Lugs are not supplied with
these transformers. Eaton
recommends that external
cables be rated 75°C for
ventilated designs.
Sound Levels
All Eaton 600 volt class
general-purpose dry-type
distribution transformers are
designed to meet NEMA
ST-20 sound levels listed
here. These are the sound
levels measured in a
soundproof environment.
Actual sound levels
measured at an installation
will likely be higher due to
electrical connections and
environmental conditions.
Lower sound levels are
available and should be
specified when the
transformer is going to be
installed in an area where
sound may be a concern.
For additional information,
please refer to Section 2.7
Page V2-T2-195.

Technical Data and Specifications
Frequency
Eaton standard dry-type
distribution transformers are
designed for 60 Hz operation.
Transformers required for
other frequencies must be
specifically designed.
Overload Capability
Short-term overload is
designed into transformers as
required by ANSI. Dry-type
distribution transformers will
deliver 200% nameplate load
for one-half hour, 150% load
for one hour and 125% load
for four hours without being
damaged, provided that a
constant 50% load precedes
and follows the overload.
See ANSI C57.96-01.250 for
additional limitations.
Continuous overload capacity
is not deliberately designed
into a transformer because
the design objective is to be
within the allowed winding
temperature rise with
nameplate loading.
Insulation System and
Temperature Rise
Industry standards classify
insulation systems and rise as
shown below:
Insulation System
Classification
The design life of transformers
having different insulation
systems is the same—the
lower-temperature systems
are designed for the same life
as the higher-temperature
systems.
Winding Terminations
Eaton recommends that
external cables be rated 90°C
(sized at 75°C ampacity) for
encapsulated designs and
75°C for ventilated designs.

Sound Levels
All Eaton 600 volt class
general-purpose dry-type
distribution transformers are
designed to meet NEMA
ST-20 sound levels listed
here. These are the sound
levels measured in a
soundproof environment.
Actual sound levels
measured at an installation
will likely be higher due to
electrical connections and
environmental conditions.
Lower sound levels are
available and should be
specified when the
transformer is going to be
installed in an area where
sound may be a concern.
Average Sound Levels

Product Description
Note: The following pages
provide listings for most standard
transformer ratings and catalog
numbers. For other ratings or
catalog numbers not shown,
or for special enclosure types
(including stainless steel), refer
to Eaton.
●Suitable for indoor or
outdoor applications
●Totally enclosed, non-
ventilated enclosures
rated NEMA 3R
●220°C insulation system
●150°C rise standard;
115°C or 80°C rise optional
Application Description
Totally enclosed non-
ventilated dry-type
transformers are for special
applications, where because
of adverse atmospheric
conditions it is desirable to
use a dry-type non-ventilated
transformer vs. the ventilated
standard unit, which has
openings in its enclosure
to allow air to flow directly
over the core and coil.
In applications where the
atmosphere contains
conductive, corrosive, or
combustible materials, which
might damage a transformer,
or lint and dust flyings that
might block the ventilation
passages, the non-ventilated
transformer is highly suited.
It has no openings in the
enclosure. Heat is dissipated
by radiating from the surface
area of the enclosure.
Consequently, the enclosures
are larger than those of the
standard ventilated type.
Non-ventilated transformers
are suited for application in
the textile, chemical,
automotive, petrochemical,
foundry, cement, food, paper
and other industries.
Features, Benefits

shown below:
Insulation System
Classification
The design life of transformers
having different insulation
systems is the same—the
lower-temperature systems
are designed for the same life
as the higher-temperature
systems.
Enclosures
Eaton totally enclosed,
non-ventilated transformers,
Types DS-3E and DT-3E,
use a NEMA 3R rated
enclosure as standard.
Winding Terminations
Primary and secondary
windings are terminated
in the wiring compartment.
Totally enclosed non-
ventilated transformers
have leads brought out to
aluminum pads that are
pre-drilled to accept Cu/Al
lugs. Lugs are not supplied
with these transformers.
Eaton recommends external
cables be rated 75°C for
ventilated designs.
Series-Multiple Windings
Series-multiple windings
consist of two similar coils
in each winding that can be
connected in series or parallel
(multiple). Transformers with
series-multiple windings are
designated with an “x” or
“/” between the voltage
ratings, such as voltages of
“120/240” or “240 x 480.”
If the series-multiple winding
is designated by an “x,” the
winding can be connected
only for a series or parallel.
With the “/” designation,
a mid-point also becomes
available in addition to the
series or parallel connection.
As an example, a 120 x 240
winding can be connected
for either 120 (parallel) or
240 (series), but a 120/240
winding can be connected for
120 (parallel), or 240 (series),
or 240 with a 120 mid-point.
Note: The preceding pages
provide listings for most standard
transformer ratings and catalog
numbers. For all-copper and
bolt-on-breaker designs, contact
Eaton. For other ratings or catalog
numbers not shown, or for special
enclosure types (including
stainless steel), refer to Eaton.

Distribution Transformers
Accessories
Please refer to Section 2.7 Page V2-T2-191.
Technical Data and Specifications
Frequency
Eaton standard dry-type
distribution transformers are
designed for 60 Hz operation.
Transformers required for
other frequencies are
available and must be
specifically designed.
Overload Capability
Short-term overload is
designed into transformers as
required by ANSI. Dry-type
distribution transformers will
deliver 200% nameplate load
for one-half hour, 150% load
for one hour, and 125% load
for four hours without being
damaged, provided that a
constant 50% load precedes
and follows the overload.
See ANSI C57.96-01.250 for
additional limitations.
Continuous overload capacity
is not deliberately designed
into a transformer because
the design objective is to be
within the allowed winding
temperature rise with
nameplate loading.
Insulation System and
Temperature Rise
Industry standards classify
insulation systems and rise as
shown below:
Insulation System
Classification
The design life of transformers
having different insulation
systems is the same—the
lower-temperature systems
are designed for the same life
as the higher-temperature
systems.
Enclosures
Eaton encapsulated
transformers, Types EPZ
and EPTZ, use a NEMA 3R
rated enclosure.
Sound Levels
All Eaton 600 volt class
general-purpose dry-type
distribution transformers are
designed to meet NEMA
ST-20 sound levels listed
here. These are the sound
levels measured in a
soundproof environment.
Actual sound levels
measured at an installation
will likely be higher due to
electrical connections and
environmental conditions.
Lower sound levels are
available and should be
specified when the
transformer is going to be
installed in an area where
sound may be a concern.
Winding Terminations
Lugs are not supplied with
these transformers. Eaton
recommends that external
cables be rated 90°C
sized at 75°C ampacity) for
encapsulated designs and
75°C for ventilated designs.
Nominal and tap leads come
out of the transformer through
pipe elbows. Connections
should be made to an adjacent
explosion-proof junction box.
Unused tap leads must be
properly insulated prior to
energization. EPZ and EPTZ
transformers are UL and
cUL listed.
Series-Multiple Windings
Series-multiple windings
consist of two similar coils in
each winding that can be
connected in series or parallel
(multiple). Transformers with
series-multiple windings are
designated with an “x” or
“/” between the voltage
ratings, such as voltages of
“120/240” or “240 x 480.”
If the series-multiple winding
is designated by an “x,” the
winding can be connected
only for a series or parallel.
With the “/” designation, a
mid-point also becomes
available in addition to the
series or parallel connection.
As an example, a 120 x 240
winding can be connected
for either 120 (parallel) or
240 (series), but a 120/240
winding can be connected for
120 (parallel), 240 (series) or
240 with a 120 mid-point.

Application Description
The basic purpose of a
transformer is voltage
transformation as near as
practically possible to the
load for economy and
distribution of power.
Typical loads for dry-type
distribution transformers
include lighting, heating, air
conditioners, fans and
machine tools. Such loads
are found in commercial,
institutional, industrial and
residential structures.
Open core and coil
assemblies are typically
used by panel builders and
equipment OEM customers
who incorporate the entire
transformer into their
structures, making these
assemblies a versatile option
to purchasing a standard,
enclosed transformer and
discarding the unneeded
enclosure parts.

Please refer to Section 2.7 Page V2-T2-191.
Technical Data and Specifications
Frequency
Eaton standard dry-type
distribution transformers are
designed for 60 Hz operation.
Transformers required for
other frequencies are
available and must be
specifically designed.
Overload Capability
Short-term overload is
designed into transformers as
required by ANSI. Dry-type
distribution transformers will
deliver 200% nameplate load
for one-half hour, 150% load
for one hour, and 125% load
for four hours without being
damaged, provided that a
constant 50% load precedes
and follows the overload.
See ANSI C57.96-01.250 for
additional limitations.
Continuous overload capacity
is not deliberately designed
into a transformer because
the design objective is to be
within the allowed winding
temperature rise with
nameplate loading.
Insulation System and
Temperature Rise
Industry standards classify
insulation systems and rise as
shown below:
Insulation System
Classification
The design life of transformers
having different insulation
systems is the same—the
lower-temperature systems
are designed for the same life
as the higher-temperature
systems.
Enclosures
Eaton ventilated transformers
Types DS-3M and DT-3M use
a NEMA 2 rated (drip-proof)
enclosure as standard, and
are rated NEMA 3R with the
addition of weathershields.
Eaton encapsulated
transformers Types EPM
and EPTM use a NEMA 3R
rated enclosure.
Winding Terminations
Primary and secondary
windings are terminated
in the wiring compartment.
Encapsulated units have
copper leads or stabs
brought out for connections.
Ventilated transformers
have leads brought out to
aluminum pads that are pre-
drilled to accept Cu/Al lugs.
Lugs are not supplied with
these transformers. Eaton
recommends that external
cables be rated 90°C
(sized at 75°C ampacity) for
encapsulated designs and
75°C for ventilated designs.
Series-Multiple Windings
Series-multiple windings
consist of two similar coils
in each winding that can be
connected in series or parallel
(multiple). Transformers with
series-multiple windings are
designated with an “x” or “/”
between the voltage ratings,
such as voltages of “120/240”
or “240 x 480.” If the series-
multiple winding is designated
by an “x,” the winding can be
connected only for a series
or parallel. With the “/”
designation, a mid-point also
becomes available in addition
to the series or parallel
connection. As an example,
a 120 x 240 winding can be
connected for either 120
(parallel) or 240 (series), but
a 120/240 winding can be
connected for 120 (parallel),
240 (series) or 240 with
a 120 mid-point.

Sound Levels
All Eaton 600 volt class
general-purpose dry-type
distribution transformers are
designed to meet NEMA
ST-20 sound levels listed
here. These are the sound
levels measured in a
soundproof environment.
Actual sound levels
measured at an installation
will likely be higher due to
electrical connections and
environmental conditions.
Lower sound levels are
available and should be
specified when the
transformer is going to be
installed in an area where
sound may be a concern.
For additional information,
please refer to Section 2.7

●Suitable for indoor or
outdoor applications
●Totally enclosed, non-
ventilated enclosures
●Enclosures are
NEMA 3R rated
●Mountable in any position
indoors and upright-only
outdoors
●180ºC insulation system
●115°C rise standard;
80°C rise optional
●Available in single-phase
ratings through 7.5 kVA
Application Description
A buck-boost transformer is
used to provide an economical
method of correcting a lower
or higher voltage rating more
suitable for efficient operation
of electrical equipment.
Type EP buck-boost
transformers are small kVA,
single-phase transformers
with dual primary and dual
secondary windings, and
are usually connected as
autotransformers by using
one unit for single-phase
applications and either two
or three units banked for three-
phase operation. They are
primarily used for motor
operation and should not be
used for motor control circuits,
to correct fluctuating line
voltage or to obtain a neutral
on a delta system. Buck-boost
transformers are ideally suited
for use with low voltage
lighting systems, such as
outdoor lighting.
Features, Benefits
and Functions
●60 Hz operation
●600 volt class insulation
●Short-term overload
capability as required
by ANSI
●Meet NEMA ST-20
sound levels
Standards and Certifications
●UL listed
●CSA certified
Industry Standards
All Eaton dry-type distribution
and control transformers are
built and tested in accordance
with applicable NEMA, ANSI
and IEEE Standards. All
600 volt class transformers
are UL listed unless
otherwise noted.
Seismically Qualified
Eaton-manufactured dry-type
distribution transformers are
seismically qualified, and
exceed requirements of the
International Building Code
(IBC) and California Code

Product Selection
For quick selection data,
refer to the tables on this
and the following pages.
Selection Requirements
You should have the following
information before selecting a
buck-boost transformer:
Line Voltage
The voltage that you want
to buck (decrease) or boost
(increase). This can be found
by measuring the supply line
voltage with a voltmeter.
Load Voltage
The voltage at which your
equipment is designed to
operate. This is listed on
the nameplate of the
load equipment.
Load Amperes or Load kVA
You do not need to know
both—one or the other is
sufficient for selection
purposes. This information
usually can be found on the
nameplate of the equipment
that you want to operate.
Frequency
The supply line frequency
must be the same as the
frequency of the equipment
to be operated—Eaton’s
buck-boost transformers
operate at 60 Hz only.
Phase
The supply line should be
the same as the equipment
to be operated—either single-
or three-phase.
Transformer Interconnection
For three-phase applications,
interconnections of
transformers should be
made in a junction box.
Two or three transformers
may be used depending
on an open delta (2) or
wye (3) connection.
5-Step Selector
The tables that follow will
simplify the selection of the
buck-boost transformers.
There are no calculations
needed; simply follow these
five steps:
1. Refer to the table having
the same output voltage
as the equipment you
want to operate. For
example, if you are
installing a 240 volt
6 kVA single-phase
load use selection table
on the page.
2. Select the available line
voltage across the top of
the chart that is closest
to the actual supply
voltage. Therefore, for
example, if the available
line voltage is 213 volts,
use the 212 volt column.
3. Read down the column
until you reach an output
kVA or amps rating equal
to or greater than the
load requirements. Since
6 kVA, in the example, is
not listed, use the next
higher rating, or 7.5 kVA.
4. Read across to the far
left columns for the
catalog number and
quantity of transformers
for your application. In
this case, you will need
one (1) catalog number
S10N06P01P.
5. Connect the buck-boost
transformer(s) you have
selected in accordance
with the connection
diagram specified at the
bottom of the available
line voltage column. In
this example, Diagram
“F” would be used.
Note: For single-phase
connections and three-phase
open delta connections, inputs
and outputs may be reversed.
kVA capacity remains constant.

Accessories
Please refer to Section 2.7 Page V2-T2-191.
Technical Data and Specifications
Frequency
Eaton buck-boost
transformers are designed
for 60 Hz operation.
Overload Capability
Short-term overload is
designed into transformers as
required by ANSI. Dry-type
distribution transformers will
deliver 200% nameplate load
for one-half hour, 150% load
for one hour, and 125% load
for four hours without being
damaged, provided that a
constant 50% load precedes
and follows the overload.
See ANSI C57.96-01.250
for additional limitations.
Continuous overload capacity
is not deliberately designed
into a transformer because
the design objective is to be
within the allowed winding
temperature rise with
nameplate loading.
Insulation System and
Temperature Rise
Industry standards classify
insulation systems and rise as
shown below:
Insulation System
Classification
The design life of transformers
having different insulation
systems is the same—the
lower-temperature systems
are designed for the same life
as the higher-temperature
systems.
Enclosures
Eaton encapsulated buck-
boost transformers use a
NEMA 3R rated enclosure.
Winding Terminations
Primary and secondary
windings are terminated in
the wiring compartment.
Encapsulated units have
copper leads or stabs brought
out for connections. Lugs
are not supplied with
these transformers. Eaton
recommends that external
cables be rated 90°C
(sized at 75°C ampacity) for
encapsulated designs.
Series-Multiple Windings
Series-multiple windings
consist of two similar coils
in each winding that can be
connected in series or parallel
(multiple). Transformers with
series-multiple windings are
designated with an “x” or
“/” between the voltage
ratings, such as voltages of
“120/240” or “240 x 480.”
If the series-multiple winding
is designated by an “x,” the
winding can be connected
only for a series or parallel.
With the “/” designation,
a mid-point also becomes
available in addition to the
series or parallel connection.
As an example, a 120 x 240
winding can be connected for
either 120 (parallel) or 240
(series), but a 120/240
winding can be connected for
120 (parallel), 240 (series) or
240 with a 120 mid-point.

Sound Levels
All Eaton 600 volt class
general-purpose dry-type
distribution transformers are
designed to meet NEMA
ST-20 sound levels listed
here. These are the sound
levels measured in a
soundproof environment.
Actual sound levels
measured at an installation
will likely be higher due to
electrical connections and
environmental conditions.
Lower sound levels are
available and should be
specified when the
transformer is going to be
installed in an area where
sound may be a concern.
For additional information,
please refer to Section 2.7
Page V2-T2-195.
Note: When installation is to be
made on a grounded system,
consideration must be given to
the resulting voltage. Thus, on a
208 grounded wye/120 system,
the voltage can be boosted to 240
volts but the voltage to ground
will be 139 volts. If 240/120 volts
with a mid-point ground is
needed, a standard two-winding
transformer must be used.
The following formulas can
be used to calculate specific
requirements.

Single-Phase Transformers
How to Select Single-Phase Units
1. Determine the primary (source) voltage—the voltage
presently available.
2. Determine the secondary (load) voltage—the voltage
needed at the load.
3. Determine the kVA load:
– If the load is defined in kVA, a transformer can be
selected from the tabulated data
– If the load rating is given in amperes, determine the load
kVA from the chart (below right). To determine kVA when
volts and amperes are known, use the formula:
– If the load is an AC motor, determine the minimum
transformer kVA from the chart at the right
– Select a transformer rating equal to or greater than
the load kVA.
4. Define tap arrangements needed.
5. Define temperature rise.
Using the above procedure, select the transformer from the
listings in this catalog.
Single-Phase AC Motors
Full Load Current in Amperes—Single-Phase Circuits
Notes
1If motors are started more than once per hour, increase minimum transformer kVA by 20%.
When motor service factor is greater than 1, increase full load amperes proportionally.
Example: If service factor is 1.15, increase above ampere values by 15%.

Transformer Standards, Technical Data and Accessories
Three-Phase Transformers
How to Select Three-Phase Units
1. Determine the primary (source) voltage—the voltage
presently available.
2. Determine the secondary (load) voltage—the voltage
needed at the load.
3. Determine the kVA load:
– If the load is defined in kVA, a transformer can be
selected from the tabulated data
– If the load rating is given in amperes, determine the load
kVA from the chart (below right). To determine kVA when
volts and amperes are known, use the formula:
– If the load is an AC motor, determine the minimum
transformer kVA from the chart at the right
– Select a transformer rating equal to or greater than
the load kVA
4. Define tap arrangements needed.
5. Define temperature rise.
Using the above procedure, select the transformer from the
listings in this catalog.
Three-Phase AC Motors
Full Load Current in Amperes—Three-Phase Circuits
Notes
1If motors are started more than once per hour, increase minimum transformer kVA by 20%.
When motor service factor is greater than 1, increase full load amperes proportionally.
Example: If service factor is 1.15, increase above ampere values by 15%.

Weathershield Kit
A weathershield kit
consisting of a front and rear
cover shield must be installed
on all ventilated dry-type
distribution transformers
when the unit is located
outdoors. The shields
protect the transformer top
ventilation openings against
rain but allow for proper
ventilation. Field installation
hardware is not required.
Refer to specific transformer
listing for selection of
weathershield kit. Proper
installation provides a
NEMA 3R rating.
Note: For 316 stainless steel,
add the suffix ‘S’ to the catalog
number.

used to allow front access
to the rear terminals on most
500 and 750 kVA transformers
(transformers on frames 919
and 920) when insufficient
space is available at the rear
of the transformer. Eaton
recommends a minimum
6-inch clearance from the wall
to maintain proper ventilation.

Transformer Standards, Technical Data and Accessories
Technical Data and Specifications
Customer-Furnished
Connecting Cables
Eaton recommends that
external cables be rated 90°C
(sized at 75°C ampacity) for
encapsulated designs and
75°C for ventilated designs.
Primary and secondary
terminal lugs are not
included. Lug kits are
available separately.
Overload Capability
Short-term overload capacity is
designed
into transformers as
required by ANSI. Dry-type
distribution transformers will
deliver 200% nameplate load
for one-half hour, 150% load
for one hour and 125% load
for four hours without being
damaged, provided that a
constant 50% load precedes
and follows the overload.
See ANSI C57.96-01.250
for additional limitations.
Continuous overload capacity
is not deliberately designed
into a transformer because
the design objective is to be
within the allowed winding
temperature rise with
nameplate loading.
Seismically Qualified
Eaton manufactured dry-type
distribution transformers are
seismically qualified, and
exceed requirements of the
Uniform Building Code (UBC)
and California Code Title 24.
Taps
Primary taps are available
in most ratings to allow
compensation for source
voltage variations.
Series-Multiple Windings
Series-multiple windings
consist of two similar coils in
each winding that can be
connected in series or parallel
(multiple). Transformers with
series-multiple windings are
designated with a “x” or
“/” between the voltage
ratings, such as voltages of
“120/240” or “240 x 480.”
If the series-multiple winding
is designated by an “x,” the
winding can
be connected
only for a series or parallel.
With the “/” designation,
a midpoint also becomes
available in addition to the
series or parallel connection.
As an example, a 120 x 240
winding can be connected
for either 120 (parallel) or
240 (series), but a 120/240
winding can be connected for
120 (parallel), 240 (series) or
240 with a 120 midpoint.
Enclosures
Eaton’s ventilated
transformers—Types DS-3,
DT-3, MD and KT—use a
NEMA 2 rated (drip-proof)
enclosure as standard, and
are rated NEMA 3R with the
addition of weathershields.
Eaton encapsulated—Types
EP, EPT, EPZ and EPTZ—
and totally enclosed, non-
ventilated (Types DS-3E and
DT-3E) transformers use a
NEMA 3R rated enclosure.
Buck-Boost Transformers
An autotransformer has only
one winding, and is therefore
smaller and more economical
than the conventional two-
winding transformer. In an
autotransformer, the primary
and secondary are electrically
and mechanically connected.
The required secondary
voltage is obtained by
“tapping-off” from the
single winding.
Buck-boost autotransformers
are insulated units with
120 x 240 or 240 x 480 volt
primaries and 12/24, 16/32 or
24/48 volt secondaries, and
provide a very economical
method for minor voltage
adjustments where circuit
isolation is not needed.
Autotransformers can be
used only where local
electrical codes permit,
and isolation of the two
circuits is not required.
Nonlinear Ratings
The transformers shall be
specifically designed to
supply circuits with a
harmonic profile equal to
or less than a K-factor of
4 or 13, as described in the
following table, without
exceeding specified
temperature rise.
Nonlinear Ratings
Sound Levels
All Eaton 600 volt class
general-purpose dry-type
distribution transformers are
designed to meet NEMA
ST-20 sound levels listed
here. These are the sound
levels measured in a
soundproof environment.
Actual sound levels
measured at an installation
will likely be higher (up to
15 dB greater) due to
electrical connections and
environmental conditions.
Lower sound levels are
available and should be
specified when the
transformer is going to be
installed in an area where
sound may be a concern.
All Eaton general-purpose
dry-type distribution
transformers are designed
with sound levels lower than
NEMA ST-20 maximum levels.
However, consideration
should be given to the
specific location of the
transformers and their
installation to minimize
the potential for sound
transmission to surrounding
structures and sound
reflection. It is suggested
that the following installation
methods be included:
1. If possible, mount the
transformer away from
corners of walls or
ceilings. For installation
that must be near a
corner, use sound-
absorbing materials on
the walls and ceilings if
necessary to eliminate
reflection.
2. Provide a solid
foundation for mounting
the transformer and
then use vibration
dampening mounts if
not already provided in
the transformer. (Eaton
encapsulated EP/EPT
designs use a special
encapsulation system
and ventilated DS/DT-3
designs contain a built-in
vibration dampening
system to minimize
and isolate sound
transmission.)
3. Provide flexible conduit
to make the connections
to the transformer.
4. Locate the transformer
as far as possible from
areas where high sound
levels are undesirable.

Transformer Standards, Technical Data and Accessories
Glossary of Transformer Terms
Air cooled: A transformer
that is cooled by the natural
circulation of air around, or
through, the core and coils.
Ambient noise level: The
existing or inherent sound
level of the area surrounding
the transformer, prior to
energizing the transformer.
Measured in decibels.
Ambient temperature:
The temperature of the air
surrounding the transformer
into which the heat of the
transformer is dissipated.
Ampacity: The current-
carrying capacity of an
electrical conductor under
stated thermal conditions.
Expressed in amperes.
Ampere: The practical unit
of electric current.
Attenuation: A decrease
in signal power or voltage.
Unit of measure is dB.
Autotransformer:
A transformer in which part
of the winding is common
to both the primary and the
secondary circuits.
Banked: Two or more single-
phase transformers wired
together to supply a three-
phase load. Three single-
phase transformers can be
“banked” together to support
a three-phase load. For
example, three 10 kVA single-
phase transformers “banked”
together will have a 30 kVA
three-phase capacity.
BIL: Basic impulse level.
The ability of a transformer’s
insulation system to
withstand high voltage
surges. All Eaton 600V-class
transformers have a 10 kV
BIL rating.
BTU: British thermal unit.
In North America, the term
“BTU” is used to describe
the heat value (energy
content) of fuels, and also
to describe the power of
heating and cooling systems,
such as furnaces, stoves,
barbecue grills and air
conditioners. When used
as a unit of power, BTU
“per hour” (BTU/h)
is understood, though this
is often abbreviated to
just “BTU.”
Buck-boost: The name
of a standard, single-phase,
two-winding transformer
application with the low
voltage secondary windings
connected as an
autotransformer for boosting
(increasing) or bucking

amounts. Applications can
either be single-phase or
three-phase.
CE: Mark to indicate third-
party approved or self-
certification to specific
requirements of the
European community.
Celsius (centigrade): Metric
temperature measure.
°F = (1.8 x °C) + 32
°C = (°F-32) / 1.8
Center tap: A tap at the mid-
point of a winding. The center
tap on three-phase delta-delta
transformers is called a
lighting tap. It provides 5%
of the transformer’s kVA for
single-phase loads.
Certified tests: Actual values
taken during production tests
and certified as applying to a
given unit shipped on a
specific order. Certified tests
are serial number–specific.
Common mode: Electrical
noise or voltage fluctuation
that occurs between all of the
line leads and the common
ground, or between ground
and line or neutral.
Compensated transformer:
A transformer with a turns
ratio that provides a higher
than nameplate output
(secondary) voltage at no
load, and nameplate output
(secondary) voltage at rated
load. It is common for small
transformers (2 kVA and less)
to be compensated.
Conductor losses: Losses
(expressed in watts) in
a transformer that are
incidental to carrying a load:
coil resistance, stray loss
due to stray fluxes in the
windings, core clamps, and
the like, as well as circulating
currents (if any) in parallel
windings. Also called load
losses.
Continuous rating: The load
that a transformer can handle
indefinitely without
exceeding its specified
temperature rise.
Core losses: Losses
(expressed in watts) caused
by magnetization of the
core and its resistance to
magnetic flux. Also called
no-load losses or excitation
losses. Core losses are
always present when the
transformer is energized.
CSA: Canadian Standards
Association. The Canadian
equivalent of Underwriters
Laboratories (UL).
CSL3: Candidate Standard
Level 3 (CSL3) design
criteria developed by the
U.S. Department of Energy.
This term is used when
considering the maximum,
practical efficiency of a
transformer.
cUL: Mark to indicate
UL Certification to specific
CSA Standards.
Decibel (dB): Unit of
measure used to express
the magnitude of a change
in signal or sound level.
Delta connection: A
standard three-phase
connection with the ends
of each phase winding
connected in series to form a
closed loop with each phase
120 degrees from the other.
Sometimes referred to as
three-wire.
Dielectric tests: Tests that
consist of the application
of a voltage higher than the
rated voltage for a specified
time for the purpose of
determining the adequacy
against breakdowns of
insulating materials and
spacings under normal
conditions.
Dry-type transformer: A
transformer in which the core
and coils are in a gaseous or
dry compound insulating
medium. A transformer that
is cooled by a medium other
than a liquid, normally by the
circulation of air.
E3: Eaton’s version of a CSL3
transformer.
Eddy currents: The currents
that are induced in the body
of a conducting mass by the
time variation of magnetic
flux or varying magnetic field.
Efficiency: The ratio of the
power output from a
transformer to the total
power input. Typically
expressed as a %.
Electrostatic shield: Copper
or other conducting sheet
placed between primary and
secondary windings, and
grounded to reduce electrical
interference and to provide
additional protection from
line-to-line or line-to-ground
noise. Commonly referred to
as “Faraday shield.”
Encapsulated transformer:
A transformer with its coils
either dipped or cast in
an epoxy resin or other
encapsulating substance.
Enclosure: A surrounding
case or housing used to
protect the contained
equipment against external
conditions and prevent
personnel from accidentally
contacting live parts.
Environmentally preferable
product: A product that has
a lesser or reduced negative
effect on human health
and the environment when
compared to competing
products that serve the same
purpose. This comparison
may consider raw materials
acquisition, production,
manufacturing, packaging,
distribution, reuse, operation,
maintenance and disposal
of the product. This term
includes recyclable products,
recycled products and
reusable products.

Surge Suppressors). The
primary safety standard for
transient voltage surge
suppressors (TVSS) has
undergone major revisions

conductive material that
can be energized under
conditions of normal use.
Load losses: I2R losses
in windings. Also see
conductor losses.

Frequently Asked Questions About Transformers
Can 60 Hz transformers be used
at other frequencies?
Transformers rated for 60 Hz
can be applied to circuits with
a higher frequency, as long as
the nameplate voltages are
not exceeded. The higher the
frequency that you apply to
a 60 Hz transformer, the
less voltage regulation you
will have. 60 Hz transformers
may be used at lower
frequencies but only at
reduced voltages
corresponding to the
reduction in frequency. For
example, a 480 to 120 volt
60 Hz transformer can carry
rated kVA at 50 Hz but
ONLY when applied as a
400 to 100 volt transformer
(50/60 x 480 = 400).
Can single-phase transformers
be used on a three-phase
source?
Yes. Any single-phase
transformer can be used
on a three-phase source by
connecting the primary
terminals of the single-phase
transformer to any two wires
of a three-phase system. It
does not matter whether the
three-phase source is three-
phase three-wire or three-
phase four-wire. The output
of the transformer will be
single-phase.
Can transformers be used to
create three-phase power from
a single-phase system?
No. Single-phase
transformers alone cannot
be used to create the phase-
shifts required for a three-
phase system. Phase
shifting devices (reactors
or capacitors) or phase
converters in conjunction
with transformers are
required to change single-
phase power to three-phase.
What considerations need to
be taken into account when
operating transformers at
high altitudes?
At altitudes greater than
3300 feet (1000 meters),
the density of the air is less
than at lower elevations. This
reduces the ability of the air
surrounding a transformer to
cool it, so the temperature
rise of the transformer is
increased. Therefore, when a
transformer is being installed
at altitudes greater than
3300 feet above sea level,
it is necessary to derate the
usable capacity of the
transformer. The table below
lists the derating factors.
As an example, a 75 kVA
480V–208Y/120V transformer
installed at 10,000 feet needs
to be derated by 4%. Instead
of 208A output, the usable
current is only 199A.
What considerations need to
be taken into account when
operating transformers where
the ambient temperature
is high?
Eaton’s dry-type transformers
are designed in accordance
with ANSI standards to
operate in areas where the
average maximum ambient
temperature is 40°C. For
operation in ambient
temperatures above 40°C,
there are two options:
1. Order a custom designed
transformer made for the
specific application.
2. Derate the nameplate
kVA of a standard
transformer by 8% for
each 10°C of ambient
above 40°C.
What is the normal life
expectancy of a transformer?
When a transformer is
operated under ANSI/IEEE
basic loading conditions
ANSI C57.96), its normal life
expectancy is 20 years. The
ANSI/IEEE basic loading
conditions are:
A. The transformer is
continuously loaded
at rated kVA and
rated voltages.
B. The average temperature
of the ambient air during
any 24-hour period is
equal to 30°C and at
no time exceeds 40°C.
C. The altitude where the
transformer is installed
does not exceed
3300 feet (1000 meters).
What are insulation classes?
Insulation classes were
originally used to distinguish
insulating materials operating
at different temperatures. In
the past, letters were used
for the different designations.
Recently, insulation system
temperatures (°C) have
replaced the letters’
designations.
Insulation Classes
How do you know if the
enclosure temperature is
too hot?
UL and CSA standards
strictly regulate the
highest temperature that
an enclosure can reach. For
ventilated transformers, the
temperature of the enclosure
should not increase by more
than 50°C in a 40°C ambient
at full rated current. For
encapsulated transformers,
the temperature of the
enclosure should not increase
by more than 65°C in a
25°C ambient at full rated
current. This means that
it is permissible for the
temperature of the enclosure
to reach 90°C (194°F).
Although this temperature is
very warm to the touch, it is
within the allowed standards.
A thermometer should be
used to measure enclosure
temperatures, not your hand.
Can transformers be reverse-
connected (reverse-fed)?
Yes, with limitations. Eaton
single-phase transformers
rated 3 kVA and larger can be
reverse-connected without
any loss of kVA capacity
or any adverse effects.
Transformers rated 2 kVA
and below, because there is a
turns ratio compensation on
the low voltage winding that
adjusts voltage between no
load and full load conditions,
should not be reverse-fed.
Three-phase transformers
with either delta-delta or
delta-wye configurations
can also be reverse-
connected for step-up
operation. When reverse-
feeding a delta-wye
connected transformer,
there are two important
considerations to take into
account: (1) The neutral is
not connected, only the
three-phase wires of the wye
system are connected, and
(2) the ground strap between
X0 and the enclosure must
be removed. Due to high
inrush currents that may be
created in these applications,
it is recommended that
you do not reverse-feed
transformers rated more
than 75 kVA. The preferred
solution is to purchase an
Eaton step-up transformer
designed specifically for
your application.

Transformer Standards, Technical Data and Accessories
Can transformers be connected
in parallel?
Yes, with certain restrictions.
For single-phase transformers
being connected in parallel,
the voltages and impedances
of the transformers must be
equal (impedances must be
within 7.5% of each other).
For three-phase transformers,
the same restrictions apply as
for single-phase transformers,
plus the phase shift of the
transformers must be the
same. For example, a delta-
wye–connected transformer
(30° phase shift) must be
connected in parallel with
another delta-wye–connected
transformer, not a delta-delta
connected–transformer
(0° phase shift).
Why is the impedance of a
transformer important?
The impedance of a
transformer is important
because it is used to
determine the interrupting
rating and trip rating of the
circuit protection devices on
the load or line side of the
transformer. To calculate
the maximum short circuit
current on the load side of
a transformer, use the
following formula:
Maximum Short Circuit =
Load Current (Amps)
Full Load Current (Amps)
Transformer Impedance
Full load current for single-
phase circuits is:
and for three-phase circuits,
the full load current is:
Example: For a standard
three-phase, 75 kVA
transformer, rated 480 volt
delta primary and 208Y/
120 volt secondary (catalog
number V48M28T75J) and
impedance equal to 5.1%,
the full load current is:
The maximum short circuit
load current is:
The circuit breaker or fuse
on the secondary side of this
transformer would have to
have a minimum interrupting
capacity of 4083 amperes at
208 volts. NEMA ST-20 (1992).
A similar transformer with
lower impedance would
require a primary circuit
breaker or fuse with a higher
interrupting capacity.
What clearances are required
around transformers when they
are installed?
All dry-type transformers
depend upon the circulation of
air for cooling; therefore, it is
important that the flow of air
around a transformer not be
impeded. UL 1561 requires
that there be no less than
6 inches (152.4 mm) clearance
between any side transformer
with ventilation openings and
any wall or obstruction.
In compliance with
NEC 450.9, Eaton’s ventilated
transformers have a note on
their nameplates requiring
a minimum of 6 inches
(152.4 mm) clearance from
the ventilation openings and
walls or other obstructions.
This clearance only addresses
the ventilation needs of the
transformer. There may
be additional local codes
and standards that affect
installation clearances.
Transformers should not be
mounted in such a manner
that one unit will contribute
to the additional heating
of another unit, beyond
allowable temperature limits,
for example, where two units
are mounted on a wall one
above the other.
