Arresters General Information

Insulation Coordination

Arresters are used to limit voltage surges on an electrical system

to a known and controlled level. The concept of insulation

coordination means that properly installed arresters limit the

incoming voltage surges to levels within the withstand capability

of the insulating system. Arresters prevent insulation, such as

air, porcelain, oil, cable or wire insulation, etc. from breaking

down, therefore, significantly improving the reliability of the

electrical system. Figure 1 demonstrates this basic concept. The

difference between the two curves is the protective margin.

The process of correlating the insulation withstand levels of

the protected equipment and the protective characteristics of

surge arresters is known as insulation coordination. Without

sparkgaps, the insulation coordination between the metal oxide

arrester and the insulation being protected is defined by the

discharge voltage of the arrester from very short times in the

impulse region to longer times in the switching surge region. The

equivalent front-of-wave of the arrester is used to coordinate with

the chopped wave withstand value, generally defined as 1.15 x

BIL of the transformer. For station class arresters, the equivalent

front-of-wave (EFOW) of the arrester is obtained by discharging

a 10kA (5kA for intermediate arresters) impulse current wave

which produces a voltage wave cresting in 0.5 microseconds.

Discharge voltage, at a specific current level, is used to coordinate

with the equipment Basic Insulation Level (BIL). The discharge

voltage is the crest voltage that results from an 8/20 microsecond

current surge. The coordinating current selected will depend

on the shielding of the substation and other system conditions.

A typically recommended value for the coordinating current is

10kA.

The switching surge protective level is determined by

comparing the switching surge response of the arrester,

with the switching surge withstand level of the transformer,

generally defined as .83 x BIL of the transformer. The voltage of

the arrester is a function of the current. A current of 500 amperes

is used for the intermediate arresters and station class arresters

from 3-96kV. A 1000 ampere surge is used for station arresters

rated 108kV to 198kV. All current impulses have a 45/90

microsecond wave shape.

Application

Proper application of metal oxide arresters is needed to receive

appropriate performance and adequate protection. Arrester

selection depends on the application and should be based on the

level of protection needed, durability of the arrester and quality

assurance of the manufacturer.

Level of protection is the first and most important factor in

applying arresters. The purpose of an arrester is to protect system

equipment against damaging surges. The level of protection

is a function of the discharge voltage characteristics of the

arrester. The lower the discharge voltage, the greater the level

of protection provided. The discharge voltage characteristics

of distribution arresters provide excellent margins of protection

needed for even the most severe applications.

Protective margins are not the only criteria in arrester selection.

Proper performance is based on selecting the appropriate ratings

to withstand system conditions. The maximum continuous line-

to-ground voltage of the system should not exceed the MCOV

rating of the arrester. The MPS arrester ratings are in accordance

with the ANSI/IEEEC62.11-2005 Standard for Metal Oxide Surge

Arresters for AC Power Circuits. Temporary overvoltages (TOV)

can have damaging effects on metal oxide arresters. The

excellent TOV characteristics of the MOV arresters will exceed

the potential system overvoltages when properly selected.

To determine the margin of protection, the following equation is

used:

Percent Margin = Transformer Withstand Level - 1 x 100

Arrester Protective Level

A Type ZSP arrester rated 108 kV protecting a transformer with

a 450 kV BIL has the following margins of protection:

Chopped Wave Withstand - Equivalent Front of Wave

Percent Margin = 1.15 x 450 - 1 x 100 = 82 %

273.7

Full Wave Withstand - Discharge Voltage for a 10kA

Impulse Current

Percent Margin = 450 - 1 x 100 = 74%

249.2

Switching Surge Withstand - Switching Surge Voltage

Percent Margin = 0.83 x 450 - 1 x 100 = 73%

195.2

All margins are well above the minimum 20% margin recom-

mendation of the ANSI application guide C62.22.

Arresters General Information

There are four basic types of arresters defined by industry

standards. The arrester type selected for the application depends

on the equipment being protected and what level of protection is

required.

Secondary—Available in ratings up to 650 volts, secondary

arresters are used to protect equipment at the utilization voltage

level.

Distribution—Typically used for the protection of equipment on

power distribution circuits. They are available in ratings up to

36kV. This type of arrester is further defined by Normal Duty and

Heavy Duty and includes special application arresters such as

riser pole or dead front elbow type.

Intermediate—Available in ratings up to 144kV, intermediate type

arresters offer improved protective characteristics and durability.

They are generally used for protection of smaller substations, or

medium class power equipment.

Station—Available in ratings up to 216kV, station class arresters

offer the best performance among the four different types. They

are typically used to protect substation equipment, rotating

machines or other applications where premium protection is

required.

Fault Current Data

Fault current testing, also known as short circuit testing,

demonstrates an arrester failure based on the most probable

failure modes over a range of fault currents. Two failure modes

are tested: 1) a fuse wire runs along the side of the internal valve

elements to simulate an internal flashover (moisture or collar

failure), 2) overvoltage the arrester until the resistive elements

fail to simulate a system overvoltage exceeding the unit’s TOV

capability.

ANSI/IEEE C62.11 2005, specifies the test procedures and

acceptance criteria for fault current tests on surge arresters.

Temporary Overvoltage

Temporary power frequency overvoltages (TOV) can occur due

to the voltage rise on unfaulted phases during a line-to-ground

fault, the loss of the neutral ground of an effectively grounded

system, sudden loss of load, generator over speed and other

conditions. Overvoltages exceeding an arrester’s MCOV (Uc)

rating cause an increase in current, resulting in increased power

loss and temperature, thereby, affecting the arrester’s stability.

Quality Assurance

ISO 9001:2000 Certified

MacLean Power Systems metal oxide facility is ISO 9001:2000

certified. Years of extensive quality control processes easily

met the requirements of ISO certification, and has been proven

with unsurpassed field performance of arresters. MPS employs

an extensive quality system from raw materials through final

assembly.

Each block is selected for final assembly based on discharge

voltage, to assure the discharge voltage of the arrester will not

exceed published values. After final assembly, the complete

arrester once again receives a series of electrical tests including

watts loss, reference voltage and radio influence voltage. Only

units accepted by the computerized tester continue on for final

packaging and shipping.

Research and Development

Research and development is an on-going process at MPS.

Our engineers are continually striving for new materials or

processes that will lead to improved arrester performance in

the field. Specifically designed test equipment provides the

capability to properly evaluate new developments. Research

and Development is an important part of our business and

commitment to the future.

ZE Elbow Distribution Arresters

The type “ZE” arrester incorporates surge protection in a one-

piece, shielded elbow housing. It permits arrester installation on

standard separable connector bushings, maintaining the dead

front concept.

Performance

The “ZE” elbow arrester consistently withstands the following

minimum design tests:

• High Current-Short Duration: 2 current surges of 40kA

magnitude

• Low Current-Long Duration: 20 current surges of 75 amperes

magnitude and 2000 microsecond duration

• Duty Cycle: 22 discharges with a current surge of 5kA magnitude

and 8/20 microsecond wave shape

• Following each of these tests, the “ZE” arrester remains

thermally stable and the discharge voltage increase at rated

current is less than 10%

Design

The type “ZE” arrester was developed specically for protection of

underground distribution systems. It is installed at the open point

of the underground system to prevent voltage wave doubling.

When also installed at an intermediate point, voltage reections

from the open point arrester are harmlessly discharged. The

housing, made of peroxide cured EPDM rubber, is totally shielded

with a molded conductive EPDM jacket to maintain the dead front

concept. The one-piece construction requires no eld assembly.

The “ZE” dead front elbow arrester is RUS listed.

Reliability

Rigid control standards insure that all material conforms to

exacting engineering specications. Each nished arrester is

subjected to electrical tests to determine reference voltage, total

leakage current and corona levels.

Application

The type “ZE” arrester rated voltage designates the 60Hz voltage

applied across the arrester terminals during the duty cycle test. In

addition, the type “ZE” arrester Maximum Continuous Operating

Voltage (MCOV) designates the maximum power frequency

voltage that may be continuously applied across the arrester in

service. Selection of the appropriate type “ZE” rating is made on

the basis that the maximum continuous line-to-ground voltage on

the system does not exceed the MCOV of the arrester.

The 10kV, 18kV and 27kV rated arresters are designed for

application on nominal 15kV, 25kV and 35kV URD systems,

respectively. The three ratings include standard ANSI/IEEE 386

separable connector interface designs that are compatible with

major interface suppliers at each voltage level.

ZIP and ZJP Intermediate Class Surge Arresters

The type “ZIP”/“ZJP” intermediate class arresters offer the

benefits of polymer housings for system voltages up to 161kV.

The arresters are approximately 1/5 the weight of the porcelain

equivalent. Handling and installation become much easier tasks.

Also, the risk of damage to the housing is reduced compared to

porcelain.

Performance

ZIP:

3 kV through 144 kV duty cycle rating, 2.55 kV through 115 kV

MCOV, 2.4 kV through 161 kV system line-line voltage

ZJP:

3 kV through 45 kV duty cycle rating, 2.55 kV through 36.5

MCOV, 2.4 kV through 46 kV system line-line voltage

The arrester designs are tested in accordance with the latest

industry strandards for metal oxide arresters. The “ZIP”/“ZJP”

arresters consistently withstand the following minimum design

tests:

• High Current-Short Duration: 100 kA crest

• Duty Cycle per ANSI: 10 kA

• Nominal Discharge Current per IEC: 10 kA

• Line Discharge Class per IEC: Class 2

• Minimum Energy Capability: 5.0 kJ/kV MCOV

• Fault Withstand Capability:

• ZIP—50 kA rms

• ZJP—20 kA rms

• Working Cantilever Strength:

• ZIP—5000 in.-lbs.

• ZJP—720 in.-lbs.

• ZIP RUS listed

Design

The design consists of a number of metal oxide valve elements

contained within a fiberglass winding and then inserted into

the polymer housing. Type “ZIP”/“ZJP” arresters are shipped

as single units for all ratings. There is no need to combine

sections, even for the 144kV duty cycle rating. The metal oxide

valve elements combine excellent protective characteristics with

steady state per formance to maximize protec tion over many

years of service.

Fault Current Withstand

The severity of a failure depends on the duration and magnitude

of the available fault current conducting through the arrester at

the time of failure. This type of arrester, with its polymer housing,

eliminates the potential danger of porcelain fragmentation. The

design uses a fiberglass epoxy wrap to relieve the pressure that

is present during a fault.

Benefits

The use of polymer housings for our arresters provides many

benefits over porcelain designs.

• LIGHTWEIGHT—The lightweight design provides much easier

handling and installation. The polymer arresters are less than

1/5 the weight of the porcelain equivalents. The burden on

mounting structures and personnel is greatly reduced.

• REDUCED CLEARANCES—The smaller physical size of the

polymer housing and the line side of the arrester allow the

clearances to be reduced. This provides added flexibility with

design and layout since they can be used in tighter areas.

• SINGLE UNIT DESIGN—The single unit design simplifies

installation by reducing handling that was previously required

for multi-section porcelain designs. This also provides improved

contamination performance over multi-unit arresters.

• DAMAGE RESISTANT—The polymer housings resist damage

from handling where porcelain units are most vulnerable to

chipping and breakage.

• SAFETY—The “ZIP”/“ZJP” arresters minimize safety hazards

to personnel and nearby equipment that exists with porcelain

housings.

Reliability

Each completed “ZIP”/“ZJP” arrester unit must pass the following

electrical tests: reference voltage, power loss, and RIV.

Station Class Arresters

The type “ZSP” station class arresters offer the benefits of

polymer housings for system voltages up to 230kV. The arresters

are approximately 25% the weight of the porcelain equivalent.

Handling and installation become much easier tasks. Also, the

risk of damage to the housing is reduced compared to porcelain.

Performance

“ZSP” arresters are available in duty cycle ratings from 3kV

through 216kV (2.55kV through 174kV MCOV) and are designed

for system line-line voltages of 2.4kV through 230kV. The

“ZSP” arrester design is tested in accordance with the latest

industry standards for metal oxide arresters. The “ZSP” arresters

consistently withstand the following minimum design tests:

• High Current-Short Duration: 100kA crest

• Duty Cycle per ANSI: 10kA

• Nominal Discharge Current per IEC: 10kA

• Line Discharge Class per IEC: Class 2 or 3

• Minimum Energy Capability: 6.1 kJ/kV MCOV

• Fault Withstand Capability: 80kA rms

• Working Cantilever Strength: 10,000 in.-lbs.

• RUS Listed

Design

The design consists of a number of metal oxide valve ele ments

contained within a fiberglass winding and then inserted into the

polymer housing. Type “ZSP” arresters are shipped as single

units for all ratings. There is no need to combine sections, even

for the 216kV duty cycle rating. The metal oxide valve elements

combine excellent protective characteristics with steady state

performance to maximize protection over many years of service.

Fault Current Withstand

The severity of a failure depends on the duration and magnitude

of the available fault current conducting through the arrester at the

time of failure. The “ZSP” type arrester with its polymer housing

eliminates the potential danger of porcelain fragmentation. The

“ZSP” design uses a high strength fiberglass epoxy wrap to

relieve the pressure that is present during a fault. The arresters

achieved a fault withstand capability of 80kA.

Benefits

The use of polymer housings for our arresters provides many

benefits over porcelain designs.

• LIGHTWEIGHT—The lightweight design provides much easier

handling and installation. The polymer arresters are less than

1/5 the weight of the porcelain equivalents. The burden on

mounting structures and personnel is greatly reduced.

• REDUCED CLEARANCES—The smaller physical size of the

polymer housing and the line side of the arrester allow the

clearances to be reduced. This provides added flexibility with

design and layout since they can be used in tighter areas.

• SINGLE UNIT DESIGN—The single unit design simplifies

installation by reducing handling that was previously required

for multi-section porcelain designs. This also provides improved

contamination performance over multi-unit arresters.

• DAMAGE RESISTANT—The polymer housings resist damage

from handling where porcelain units are most vulnerable to

chipping and breakage.

• SAFETY—The ZSP arresters minimize safety hazards to

personnel and nearby equipment that exists with porcelain

housings.

Reliability

Each completed “ZSP” arrester unit must pass the following

electrical tests: reference voltage, power loss, and RIV.

Discharge Counter

Catalog No. 7120B0004H0001

The optional discharge counter records the number

of current discharges through the ground lead of

the arrester. A ve-digit cyclometer records each

current discharge. The counter registers impulse

discharges of an amplitude of 200 amperes or

more. No external power source is required. The

discharge counter must be used in conjunction

with insulating sub-bases.

A milliammeter comes with the discharge counter

to provide continuous reading of the total current

through the metal oxide valve elements and the

leakage current across the external polymer

insulation. A 0-30 milliampere scale is used.

Heavy external contaminants on the polymer

housing will increase the level of current registered

and may serve as an indication the polymer

housing needs washing. Steadily increasing

readings with a clean housing may be an indication

of potential problems with the arrester metal oxide

valve elements.

Transmission Line Arrester and Assemblies

Type “ZQPT”/“ZXLA”

Available for System Voltages Up to 161kV

Users of electricity have become more and more demanding over

recent years. The quality of the power they receive is critical to

their operations. Sensitive electronic equipment cannot tolerate

voltage uctuations and many problems are directed to the utility.

The heightened awareness of power quality has brought the

issue to all levels of operations, including transmission.

In the area of transmission line power quality, MPS offers the

“ZQPT”/“ZXLA” transmission line arrester and arrester insulator

assembly. The lightweight construction makes it possible to easily

mount arresters on transmission line structures. The arresters

provide a preferred path between line and ground, guarding

against insulator ashover.

Transmission line surge protection is a solution to troublesome

outages and customer dissatisfaction. State-of-the-art protection

of transmission lines using polymer MOV arresters provides

higher power quality which will improve customer satisfaction.

“ZQPT”/“ZXLA” transmission line arresters and assemblies are

available for system voltages up to 161kV. The metal oxide

blocks are specially selected and wrapped under compression

with a strong berglass wrap.

Application

“ZQPT”/“ZXLA” transmission line arresters and assemblies are

applied to:

• Improve power quality and overall line performance

• Supplement shield wire protection

• Provide protection for lines without a shield wire

• Create more space on structures by eliminating the shield

wires

• Protect both new construction and retrot

The factors that impact transmission line lightning performance

include the following: The amount of lightning activity in a given

area per year, the stroke magnitude and the wave shape of the

lightning, the tower height and the amount of nearby natural

shielding from trees or buildings, the tower footing resistance,

the presence of an overhead shield wire and the shield angle,

and the existing line insulation.

When selecting transmission line arresters for specic application,

there are several things to keep in mind. The application is usually

different for a line with an overhead shield wire than without.

The arrester rating should be coordinated with the arresters in

the substation. The transmission line arresters should be the

same rating or larger so that they do not end up protecting the

substation arresters.

The transmission line arresters should be sized by evaluating the

line voltage and the line insulation. By using a high MCOV arrester

the temporary overvoltage (TOV) capability will be increased

and the energy capability will also be greater. With the added

lightning exposure that may be expected on a transmission line,

it is helpful to have higher capabilities in these categories. Also,

higher rated arresters will not experience as much duty because

the reference voltage is higher and will not turn on as soon as

lower rated units.

Benets

Lightning is one of the major causes of power interruption.

Currently, shield wires serve as lightning protection for

transmission lines.

“ZQPT”/“ZXLA” transmission line arresters and assemblies

provide these advantages over the use of shield wire alone:

• Minimize the requirement to lower ground resistance

• Protect against backash

• Safeguard from induced surges caused by nearby lightning

• Limit effects of switching surges

• Install easily and economically

• Allow for reduction of structure BIL

• Reduce system breaker operations

• Provide protection for isolated problem areas

• Improve overall line performance

• Enhance customer relations

Surge Tec® Secondary Arresters

Electricity users, from the homeowner to big business, are

more interested today in the quality of the power they receive

than in the past, and with good reason. Advances in technology

have introduced new electronic equipment and appliances that

are more susceptible to damage by power surges. Replacing

or repairing damaged equipment is inconvenient and can be

costly.

Lightning or an interruption in the power line can generate a

power surge. These high energy surges can enter a home

or building through the electric service entrance. Once the

surge enters the building, there is a possibility that high voltages

resulting from the surge current will damage electrical wiring

or equipment. Surge Tec® arresters are designed to limit surge

voltages by discharging (bypassing) surge current to ground.

Individuals should assess their risk by evaluating the potential

impact that a power surge may have on their property. In many

cases, the cost of protection is relatively inexpensive compared

to the possible loss. The Surge Tec® arrester is designed to

provide brute force protection against surges at the service

entrance, where protection is needed the most. The family of

Surge Tec® arresters provides an excellent first line of defense

for any critical electrical service, whether it is in a home, business

or industrial applications.

Surge Arrester Application

MPS’ Surge Tec® arresters are designed for service entrance

installations. The arresters are designed for repeated operation

and continuous protection.

Surge arresters provide the path of least resistance to ground for

surges on a system. THE ARRESTERS SHOULD BE INSTALLED

BY A LICENSED ELECTRICIAN. To provide the best protection,

the lead wires should be kept as short as possible. When installed

properly, they will divert lightning surges to ground very quickly.

Surge Tec® arresters offer the first line of defense for the entire

electrical service and protect wiring, major appliances, pumps,

and heating/air conditioning equipment. For added protection to

computers, MPS recommends plug-in-strip type of device with

lower clamping voltages as a second line of defense. This type

of coordination provides excellent surge protection for the entire

electric service.

Features

Surge Tec® arresters incorporate special features that make them

stand above other Secondary Arresters and Transient Voltage

Surge Suppressors (TVSS). These arresters use a patented

(#5,502,612) fault withstand design along with replacement

indication. The arresters are available in 175 volt, 480 volt and 650

volt AC ratings for application on system voltages below 650 volts

phase to ground and operate at frequencies between 48 and 62 Hz.

The units come with 18 inch, #14 AWG solid copper wire leads and

are designed to be mounted outdoors or indoors.

• METAL OXIDE VARISTORS—Surge Tec® arresters use metal

oxide varistors (MOV). This takes advantage of our experience

with metal oxide production for the utility industry. The arresters

meet ANSI/IEEE C62.11-1993 for secondary arresters. In

addition, they have passed a 5kA Duty Cycle test. They

provide high speed response and excellent energy capability

for today’s critical electric loads.

• REPLACEMENT INDICATION—A visual indication on the front

label permits routine checks of the arrester’s operational

status. Indication windows on the label turn black if the arrester

has faulted. The arrester should be replaced when any area of

any window turns black.

• FAULT WITHSTAND CAPABILITY—The Surge Tec® secondary

arresters have a patented fault withstand design. This unique

design has been tested at high current failure modes to verify

its ability to withstand a failure without a violent fracture of the

housing. Fault current is the full available system current that the

device conducts in the event it is short circuited by conducting

a surge beyond the designed capability. This provides signifi-

cant advantages in the area of secondary voltage protection.

There currently is not a standard requirement or test specification

for fault withstand capability of secondary arresters. The Surge

Tec® arresters were tested by failing them with an overvoltage

and then applying fault currents of 4kA and 10kA. The arresters

achieved the fault withstand capability of 10kA rms without the

use of, or the requirement for, any external fusing.

• COST EFFECTIVE—The Surge Tec® arresters are very

inexpensive compared to potential equipment damage.
