INSPECTION FOR
DAMAGE IN SHIPMENT

STORAGE PRIOR TO
INSTALLATION

Check each item with the shipping manifest immediately
upon receipt of the regulator. Make a thorough visual inspection of the regulator. Check for evidence of damage
attributable to mishandling in shipment. Should any shortage or damage be found, notify the local agent of the carrier
making the delivery and make appropriate notation on the
freight bill. Any damage or shortage that is not noted on the
freight bill becomes the recipients responsibility. A claim
should be made immediately with the carrier. Please also
notify your Siemens representative as soon as possible.

Assure that the control compartment enclosure is tightly
closed, and regulator tank is sealed.

INTRODUCTION

PHYSICAL CONSIDERATIONS
•

Handling. Type JFR regulators are designed to be lifted
either by a forklift at the base or by use of lifting hooks
on the side of each tank. Each JFR regulator is provided
with either 2 or 4 lifting hooks on the side of each tank.
The number of hooks has been established to provide a
margin of safety. Use all supplied lifting hooks when
lifting.

WARNING

Type JFR voltage regulators are routinely equipped with line
bushing terminals per the following criteria.

Nameplate Line Current
Rating

Conductor Size Range
or Threaded Stud Size

50A to 300A
301A to 668A
669A to 1200A
1201 A to 2000A

#2 to 477 MCM
#2 to 800 MCM
1.125- 12 UNF-2A
1.500- 12 UNF-2A

Improper use of lifting provisions can cause death,
serious injury, or equipment damage.

Clamp type terminals for use through 668 ampere are
capable of accepting an aluminum or copper conductor.

To prevent:

Tank grounding provision consists of a 0.5-13NC tapped
hole in a steel pad for regulators rated to 300 amperes.
Above 300 ampere ratings, a stainless steel pad with two
0.5-13NC tapped holes is provided.

Do not use cover lifting eyes to lift complete unit.
Cover lifting eyes are for untanking only.

•

LINE TERMINALS AND
CONNECTIONS

Location. Type JFR regulators are designed for outdoor
installation. Any regulator may be platform or pedestal
mounted. Regulators provided with hanger brackets are
suitable for pole mounting. When the regulator is to be
installed in a substation on a pedestal it is recommended that a minimum elevation to the live connection
be established, as required by applicable codes.

ELECTRICAL CONSIDERATIONS
Type JFR regulators are commonly installed using any of
four electrical configurations.
• One regulator in single-phase application. (Figure 4A)
• Three regulators in wye on a grounded-neutral threephase system. (Figure 4D)
• Two regulators in open delta on a three-phase
ungrounded system. (Figure 4B)
• Three regulators in closed delta on a three-phase
ungrounded system. (Figure 4C)

Hazardous voltage present at the line terminals of the
bushings on the cover of the regulator.
Will cause serious injury or death.
To prevent:
De-energize the regulator before servicing.

Elevation. When the regulator will be used at an elevation
above 1000 meters (3300 feet) the kVA rating must be derated per ANSI C57.15 to assure operating temperature
limits are not exceeded.

Each of the four alternatives, when complete with switching
provisions, will take the electrical configuration as shown
on the next page.
The descriptions 'S', 'L', and 'SL' are embossed into the cover
for user convenience at time of installation.

PROTECTIVE MEASURES
Bypass Arrester. All JFR regulators are equipped with a
properly sized arrester, connected externally between the 'S'
and 'L' line terminals. The arrester is provided to protect the
series winding of the regulator from line surges. By itself, the
bypass arrester does not provide lightning protection for the
regulator.
Lightning Protection. The number of lightning arresters used
will be a discretionary decision on the part of the user,
considering such factors as isokeraunic level and degree of
risk of damage to be accepted. The minimum recommended
lightning protection consists of a properly sized arrester
between the 'S' or 'L' bushing and ground on a single phase
or a wye connected system. A delta connection system
requires the use of two arresters to accomplish minimum
protection levels. Additional protection can be obtained with
the use of arresters at both the 'S' and 'L' terminals in single
phase or wye systems and on all three terminals on a delta
system.
Figure 5A
For best results, install lightning arresters on the mounting
lugs adjacent to the bushings near the top of the tank. The
lugs are 0.5 - 13NC located on 2.5 inch centers. Ground the
arrester(s) and the regulator tank solidly to the same ground
connection. Be careful to keep the ground lead connections
as short as possible.

For this purpose, it is necessary to use the nameplate
drawing and control diagram found in the control enclosure.
1.

Refer to the Nameplate. The P2 column indicates the
correct connection for lead P2 based on the system
voltage. Using the applicable control diagram, the
terminal designation of the nameplate can be cross
referenced to the proper terminal on the 19-pin terminal
block.

2.

Depending on the regulator, there may be a second
nameplate column indicating that lead U2 should also be
connected. If so, the U2 column indicates the correct
connection for lead U2 based on the system voltage
Using the applicable control diagram, the “U” terminal
designation of the nameplate can be cross referenced to
the proper terminal on the 19-pin terminal block.

3.

For regulator equipped with fans for forced-air cooling,
another set of connections will be shown.

Thru Fault. Type JFR regulators are rated under condition of
thru-faults per ANSI C57.15.
The user is advised to provide for additional source impedance, bus sectionalizing or other means of limiting the available thru-fault current if these criteria are exceeded at the
installation.

CONTROL CONNECTIONS
Many regulators can be used at several different nominal
system voltages. It is therefore necessary to assure that the
regulator is properly connected at the 19 pin upper terminal
block for the system voltage on which the particular regulator
will be used.

NOTE

Matters specifically relating to the Accu/StatTM
control used in conjunction with the regulator are
not included in this manual. Refer to the
appropriate control instruction manual.

MAINTENANCE
Page 11

GENERAL INSTRUCTIONS

OPERATIONAL CHECKS

This manual does not represent an exhaustive survey of
maintenance steps necessary to ensure safe operation of
the regulator. Particular applications may require further procedures. Should further information be desired or should
particular problems arise which are not covered sufficiently
for the purchaser’s purposes, the matter should be referred
to the local Siemens sales representative.

Basic regulator operation can be checked while the regulator
remains in service. The output voltage can be monitored from
the control panel display under the  menu on the
“Vld” screen.

WARNING
Failure to properly maintain the regulator can result in
serious injury, death, or equipment damage. The
instructions contained herein should be carefully
reviewed, understood and followed.

• Check the calibration by following the steps in the Basic
Troubleshooting section of the Accu/Stat control panel
instruction manual.
• Run the tapchanger several steps in one direction in the
manual mode until the output voltage is outside of the
bandwidth. Return the control to automatic mode. After the
predetermined time delay, the tapchanger motor will be
observed to return the output voltage in-band. Repeat this
operation, running the tapchanger in the opposite direction.
TM

To prevent:
The following maintenance procedures should be
performed regularly:
1. Operational checks.

• Check the Vari-Amp limit switches by attempting to run the
tapchanger beyond the position to which the switches are
set. The limit switches should function to open the circuit.
Note: If the limit switch is set at the maximum 10% range and
fails to function, the tapchanger will stall against a mechanical
stop. The motor is designed to stall continuously without
damage.

2. Periodic inspection.

CAUTION
Operation of the regulator at extreme tap positions
could produce line voltages outside of operating limits
that could result in property damage.
Hazardous voltages. Will cause serious injury, death, or
equipment damage.

To prevent:

To prevent:

Operate the regulator only to judiciously determined
voltage extremes.

Always de-energize and ground the equipment before
maintenance requiring access to high voltage parts.

WARNING
WARNING
The use of unauthorized parts in the repair of the
equipment, tampering by unqualified personnel, or faulty
repair and adjustments can result in dangerous conditions
which can cause serious injury, death, or equipment
damage.
To prevent:
Follow all safety instructions contained herein, and contact
your local Siemens sales representative for replacement
parts.

Regulator may have High Internal Pressure. Can cause
serious injury, death, or equipment damage.
To prevent:
Use pressure relief valve to vent regulator before
untanking.

MAINTENANCE
Page 12

PERIODIC INSPECTION
A sample of oil from the regulator should be subjected to
dielectric breakdown test, per ASTM D-877. If found below
25kV, the oil should be changed or reconditioned. Refer to
ANSI C57.106-2002. Other tests, especially Neutralization
Number, Interfacial Tension and Power Factor are also useful
and may be preferred by particular users.
The oxidation inhibitor in the oil will be depleted over a period
of a few years and should be replaced. The inhibitor is 2, 6ditertiary-butyl-para-cresol (DBPC) at a concentration level of
0.2 to 0.3%.

When inspecting, check to be certain all hardware and connections are tight. The principal point of the internal inspection will
be the condition of the arcing contacts on the tapchanger. Since
numerous factors influence the rate of contact tip wear, no one
criteria can be stated to recommend when a contact should be
changed.
The following figure shows the possible condition of contact wear
after a period of operation. If the contact surface is less than 1/8
inch wide, the contact should be replaced. (See the Figure below)
Contacts, both movable and stationary, show normal burning and wear
once placed in service. If for any reason A1 dimensions exceed 4/5 of
A, the stationary contact should be replaced. (See the Figure below)

The time interval between internal inspections will depend
upon frequency of tapchanger operation and the load on the
regulator. Regulators subjected to numerous overloads and a
high load factor may require more frequent inspections than
those carrying normal loads. While internal inspection is not a
necessity, preventive maintenance inspections will help assure
the continuity of service.
To untank a JFR regulator, proceed as folllows:
1. Remove the regulator from service as described on
Page10.

A

A1
Hazardous voltages. Will cause serious injury, death, or
equipment damage.
To prevent:
Always de-energize and ground the equipment before
maintenance requiring access to high voltage parts.

• UPPER FILTER PRESS SEALING
If cover top cap is removed, make certain the cap is properly
sealed when replaced on cover. Siemens recommends applying
pipe sealant (Loctite PST or equivalent) around the threads of the
adapter. Furthermore, it is recommended that the seal be tested by
applying 5 psig pressure through the pressure relief valve fitting for
5 minutes, with no loss in pressure. Failure to assure seal may
allow moisture to be pulled into the unit during a cool-down cycle.

2. Place the regulator in a position where energized
overhead lines will not interfere.

• FAN MAINTENANCE

3. Operate pressure relief valve to vent regulator before untanking

Cooling fans (if equipped), require minimum attention. Fans with
plain sleeve bearings or Oil-Lite sleeve bearings should be oiled at
least once a year with SAE 10-W engine oil which does not thicken
in cold weather. Oil must be added to sleeve bearings before
starting motor for the first time after installation.

4. Remove the mounting bolts holding the control box onto
the main tank.
5. Remove all cover bolts.
6. The regulator can now be pulled from the main tank by the
cover lifting eyes.

Fans equipped with ball bearing motors are packed with grease
before shipment and should be greased at least once a year with a
soda-soap, ball-bearing grease of medium consistency furnished
by a reliable supplier.

SPECIAL FEATURES

POLARIZED DISCONNECT SWITCH
(JACK PLUG) AND HINGED
CONTROL PANEL
The Accu/StatTM control panel is hinged and may be removed completely from the regulator control box by
removing the wing nuts on the polarized jack plug and
pulling the jack from its fixed position. This will
automatically de-energize the control. It is not necessary
to bypass or de-energize the regulator to remove the
control.
A spring-loaded shorting bar in the plug automatically
short circuits the current transformer secondary when
the jack is removed.

REMOTE MOUNTING
OF CONTROL
EQUIPMENT
The Accu/StatTM control may be remotely mounted.
Remote cable is available in standard lengths of 18, 25
and 30 feet incorporating oil and moisture resistant,
color-coded conductors.

Page 13

VARI-AMPTM POSITION INDICATOR

The Vari-AmpT M feature provides a method of operating the
regulator at increased load by decreasing the range of operation. It provides operator flexibility by allowing the range of
regulation to be adjusted in 1¼ percent increments. The
various regulation ranges together with the corresponding
current capacities for standard regulators are listed on the
next page. All that is necessary to adjust the range of
regulation anywhere from ±5 percent to ±10 percent is to
turn the adjusting knobs until the proper range of regulation
is shown on the side of the position indicator. The upper and
lower limits need not be the same.
It is not necessary to remove the regulator from service to
make this adjustment. The switches are, however, in the
motor power circuit so the motor should not be running while
the switches are being set.

SPECIAL FEATURES
Page 14

OPERATION AT LESS
THAN
RATED VOLTAGE
JFR regulators may be operated at less
than the voltage for which they were designed. All system voltages for which
control system taps have been provided
are shown on the nameplate. When this
is to be accomplished it may be necessary to reconnect particular leads at the
upper 19-pin terminal block as illustrated
on page 5. When operating the regulator
at reduced voltage it must be noted that
the regulator carries a maximum current
rating which rules regardless of the
voltage (see table at right). It may
therefore be necessary to operate the
regulator at less than its nameplate kVA
rating.

Units with catalog number starting with:
10 are self cooled
11 are forced-air cooled

Regulators can be modified at factory for 50
Hz operation with appropriate de-rating of
voltage.

*Capable of carrying current corresponding
to rated kVA when operated at 7200/12470
volts ground wye.

FORCED AIR COOLING

SUBBASE ASSEMBLY

Certain regulators may be equipped for forced-air cooling and
include fans mounted on the radiators. The fans are usually
automatically controlled by means of the change in oil
temperature (see Connection Diagram). The thermometer
located in the top transformer oil contains two identical
switches which control fan operation when fan control switch is
in “Auto” position.

Subbase assemblies are available in 4-inch high increments
from 21 through 49 inches for most JFR regulators. The
proper height is selected by picking the elevation that will
provide required clearance from foundation to the live part of
the regulator bushing.

The switches are normally set to start the fans at 65°C and to
stop them at 55°C top oil temperature, but may be adjusted
plus or minus 5°C.
A thermal overload relay is mounted on each fan motor. Any
fan that develops trouble will be automatically disconnected
from the line without affecting the other fans of the system.
One fan can be removed from the radiators without affecting
the operation of the others. When fans are out of service,
care must be exercised to prevent overloading the regulator.
