ABB Surge Arresters — Buyer’s Guide
Introduction
Safe, secure and economic supply of
electricity — with ABB surge arresters
ABB surge arresters are the primary
protection against atmospheric and
switching overvoltages. They are
generally connected in parallel with the
equipment to be protected to divert
the surge current. The active elements
(ZnO-blocks) of ABB surge arresters are
manufactured using a highly non-linear
ceramic resistor material composed
largely of zinc oxide mixed with other
metal oxides and sintered together.
Extreme quality control and a large
number of tests at all stages, from raw
material until finished product, ensure
that ABB surge arresters survive the
designed stresses with ease and with
good margins. Different dimensions
permit a large variety of standard arresters as well as client-specific solutions
as regards protection levels and energy
capability.
This Buyer’s Guide deals with high
voltage surge arresters for standard
AC applications. For other applications, such as series capacitors protetion, shunt capacitor protection or DC
applications, contact your ABB sales
representative.

Definitions
Definitions
Note: The standards referred to hereunder are the latest editions of IEC
60099-4 and ANSI/ IEEE C62.11
The maximum voltage between phases
during normal service.
ANSI (MCOV)
ANSI lists the maximum continuous
operating voltage (MCOV) for all arrester
ratings used in a table. The value is used
in all tests specified by ANSI. MCOV is
less stringent as regards uneven voltage
distribution in an arrester.
Nominal discharge current (IEC)
Temporary overvoltages (TOV)
Maximum system voltage (Um)
The peak value of the lightning current
impulse which is used to classify the
arrester.
Lightning classifying current
(ANSI/IEEE)
The designated lightning current used to
perform the classification tests.
Rated voltage (Ur)
An arrester fulfilling the IEC standard must
withstand its rated voltage (Ur) for 10 s
after being preheated to 60 °C and subjected to energy injection as defined in the
standard. Thus, Ur shall equal at least the
10-second TOV capability of an arrester.
Additionally, rated voltage is used as a
reference parameter.
Note! TOV capability of EXLIM and
PEXLIM arresters exceeds the IEC
requirements.
Duty-cycle voltage rating (ANSI)
The designated maximum permissible
voltage between its terminals at which an
arrester is designed to perform its duty
cycle.
Continuous operating voltage
It is the maximum permissible r.m.s.
power frequency voltage that may be
applied continuously between the arrester terminals. This voltage is defined in
different ways (verified by different test
procedures) in IEC and ANSI.
IEC (Uc)
IEC gives the manufacturer the freedom
to decide Uc. The value is verified in the
operating duty test. Any uneven voltage distribution in the arrester shall be
accounted for.
B-1
Edition 4, 2003-10
Temporary overvoltages, as differentiated
from surge overvoltages, are oscillatory
power frequency overvoltages of relatively
long duration (from a few cycles to hours).
The most common form of TOV occurs
on the healthy phases of a system during
an earth-fault involving one or more
phases. Other sources of TOV are loadrejection, energisation of unloaded lines
etc.
The TOV capability of the arresters is
indicated with prior energy stress in the
relevant catalogues.
Residual voltage/
Discharge voltage
This is the peak value of the voltage that
appears between the terminals of an
arrester during the passage of discharge
current through it. Residual voltage
depends on both the magnitude and
the waveform of the discharge current.
The voltage/current characteristics of the
arresters are given in the relevant catalogues.
Energy capability
Standards do not explicitly define energy
capability of an arrester. The only measure
specified is the Line Discharge Class in
IEC. Often, this is not enough information
to compare different manufacturers and,
therefore, ABB presents energy capability
also in kJ/kV (Ur). This is done in 3 different ways:
Two impulses as per IEC clause 7.5.5.
This is the energy that the arrester is subjected to in the switching surge operating
duty test (clause 7.5.5.) while remaining
thermally stable thereafter against the
specified TOV and Uc.
ABB Surge Arresters — Buyer’s Guide
Definitions
Routine test energy
This is the total energy that each individual
block is subjected to in our production
tests.
Single-impulse energy
This is the maximum permissible energy,
which an arrester may be subjected to
in one single impulse of 4 ms duration or
longer and remain thermally stable against
specified TOV and Uc.
Note! Corresponding values based on Uc
are obtained by multiplying the catalogue
values by the ratio Ur/Uc.
Short-circuit capability
This is the ability of an arrester, in the
event of an overload due to any reason, to
conduct the resulting system short-circuit
current without violent shattering which
may damage nearby equipment or injure
personnel. After such an operation, the
arrester must be replaced.
The system short-circuit current may
be high or low depending on the system
impedance and earthing conditions.
Hence short-circuit capability is verified at
different current levels.
External insulation
withstand strength
It is the maximum value of the applied voltage (of a specified wave shape)
which does not cause the flashover of an
arrester. Unlike other equipment, arresters are designed to discharge internally
and the voltage across the housing can
never exceed the protective levels. Thus,
the external insulation is self-protected if
its withstand strength is higher than the
protective levels corrected for installation
altitude. The standards specify additional
safety factors, exclusive of correction for
altitude, as under:
Note! The altitude correction factors are
13% per 1 000 m (IEC) and 10% per
1000 m (ANSI).
All EXLIM and PEXLIM arresters fully comply
with IEC and ANSI standards for installations
up to 1 000 m, often with a large margin.
Pollution performance
IEC 60815 defines four levels of pollution
(from light to very heavy) and stipulates the
required creepage for porcelain housings as
indicated in the table here.
Pollution level
Specific creepage in
mm/kV (Um)
Light (L)
16
Medium (M)
20
Heavy (H)
25
Very Heavy (V)
31
In the absence of similar standards for
polymeric housings, the table also applies at
present to such housings.
The creepage distance is the length measured along the housing’s external profile and
serves as a measure of the arrester
performance in polluted environments with
respect to the risk of external flashover.
Since the mean diameter for all the standard arresters is less than 300 mm, the
specific creepage distance is the same as the
nominal creepage distance.
• IEC: 15% for short impulses and 10%
for long impulses (at sea level)
• ANSI: 20% for short impulses and 15%
for long impulses (at sea level)

Backflashover
Occurs when lightning strikes the tower
structure or overhead shield wire. The
lightning discharge current, flowing
through the tower and tower footing
impedance, produces potential differences across the line insulation.
If the line insulation strength is exceeded,
flashover occurs i.e. a backflashover.
Backflashover is most prevalent when
tower footing impedance is high.
Compact insulation lines
Transmission lines with reduced clearances between phases and between phase
and earth and with lower insulation level
withstand than for normal lines for the
same system voltage.
Protection of phase conductors from
direct lightning strokes; generally, by
means of additional conductor(s) running
on the top of the towers and grounded
through the tower structures.
Shielding angle
The included angle, usually between 20
to 30 degrees, between shield wire and
phase conductor.
Shielding failure
Occurs when lightning strikes a phase
conductor of a line protected by overhead
shield wires.
TLA
Transmission Line Arresters.
Coupling factor
is the ratio of included surge voltage on a
parallel conductor to that on a struck conductor. This factor is determined from the
geometric relationships between phase
and ground (or protected phase conductors). A value often used for estimation
purposes is 0.25.
Tower footing impedance
The impedance seen by a lightning
surge flowing from the tower base to
true ground. The risk for backflashover
increases with increasing footing
impedance.
Travelling waves
Energy capability
The energy that a surge arrester can
absorb, in one or more impulses, without

Selection of arrester
Simplified selection procedure
For a detailed Selection Guide, please
refer to ABB publications PTHVP/A
2300E and PTHVP/A 2310E.
The catalogues list the available
standard arresters from ABB of porcelain-housed arresters type EXLIM
and silicone polymer-housed arresters,
type PEXLIM.
The selection is carried out in two major
steps:
• Matching the electrical characteristics
of the arresters to the system’s electrical demands
• Matching the mechanical characteristics of the arresters to the system’s
mechanical and environmental requirements.
The final selection is reflected in the arrester type designation.

Selection of arrester
Matching the electrical characteristics
Arrester rated voltage (Ur)
For each system voltage, the tables ”Guaranteed protective data” show a range of
Ur and maximum continuous operating
voltages Uc, all of which are capable of
withstanding the actual continuous operating voltage (Uca) with sufficient margin.
Hence, the selection of Ur is only a function of the applied temporary overvoltages, TOV, (Utov), taking into account their
amplitudes and duration.
TOV are long-duration, mostly powerfrequency (p.f.) or nearly p.f. voltages,
with or without harmonics, generated
by system events. The arresters must
withstand the heat energy generated by
them.
Most commonly, a single or two-phase
earth fault leads to a TOV in the healthy
phase(s) and also in the neutral of Yconnected transformers. Its amplitude
is determined by the system earthing
conditions and its duration by the faultclearance time.
If the earth-fault factor, (k) = Utov/Uca,
is 1.4 or less, the system is considered
to be effectively earthed. Generally, this
implies a solid connection of the neutral to
the earth grid. All other forms of earthing
via an impedance or a non-earthing of the
neutral is considered as non-effective with
k = 1.73
For effectively earthed systems, the faultclearance time is generally under 1 s but it
can vary widely among different systems.
The catalogues list the values of TOV
capability for 1 and 10 s duration after
a prior energy stress (as a conservative
approach). For other durations or for specific TOV conditions, follow the procedure
hereunder:
• Consider each TOV separately.
• From the TOV curves, read off the TOV
strength factor (T) for the time corresponding to the fault-clearance time.
• Utov/T gives the min. value of Ur for
withstanding this TOV. Choose the next
higher standard rating.
• The final choice of Ur will be the highest of the Ur values obtained from the
above calculations for each TOV.

The table gives a minimum value of the arrester
rated voltage (Ur). In each case, choose the next
higher standard rating as given in the catalogue.
Note: Do not select a lower value of
Ur than obtained as above unless the
parameters are known more exactly;
otherwise the arrester may be overstressed by TOV.
Energy capability & line
discharge class
IEC classifies arresters by their nominal
discharge current. For 10 and 20 kA arresters, they are also classified by energy capability expressed as line discharge class (2
to 5) verified in a long duration current test
and a switching surge operating duty test.
In the latter, the arrester is subjected to two
impulses of a given amplitude and duration after which it must be thermally stable
against Uc. The ”class” figure roughly gives
the expected energy absorbed in
kJ/kV (Ur) per impulse. As seen in Table 2,
the ABB arresters are tested for a much
higher energy absorption capability.

Selection of arrester
Matching the electrical characteristics
Though the energy capability is mentioned
in a different manner in ANSI, the normal
range of application as above applies
even for ANSI systems.
For specific and special cases, e.g.
capacitor banks, it may be necessary to
calculate the energy capability as shown
in the IEC 60099-5 and other guides, e.g.
publication PTHVP/A 2312en.
Protection levels (Upl and Ups)
For insulation co-ordination purposes,
consider the lightning impulse protection
level (Upl) at 10 kA for Um ≤ 362 kV and
at 20 kA for higher voltages. Similarly, the
switching impulse protection levels (Ups)
for co-ordination purposes range from 0.5
kA (for Um ≤ 170 kV) to 2 kA (for Um ≥ 362
kV). The values can be read-off from the
catalogue tables or easily computed from
Table 3. In the latter case, they must be
rounded upwards.

Upl and Ups ratios for ABB arresters
Protection margins
Protection margins (in %), calculated at
co-ordinating impulse currents as per
Table 3, are defined as follows:
• Margin for lightning impulses =
((Uwl/Upl)-1) x 100, where Uwl is the
external insulation withstand of the
equipment against lightning impulses.
• Margin for switching impulses = ((Uws/
Ups)-1) x 100 where Uws is the external insulation withstand of the equipment for switching impulses.
C-4
Edition 4, 2003-10
Note! ANSI standards refer to Uwl as BIL
and Uws as BSL.
Margins are normally excellent due
to the low Upl, Ups and also that most
equipment at present have a high Uwl and
Uws. However, depending on the electrical
distance between the arrester and the
protected equipment, the Upl margin is
reduced and thus arresters fail to protect
equipment that is not in the close vicinity
of the arresters (i.e. within their protection
zone). The flexible erection alternatives
for PEXLIM arresters may be of benefit in
reducing the distance effects. Additional
line-entrance arresters may help too. For
more detailed information regarding this,
please refer to publications PTHVP/A
2310E and PTHVP/A 2120en.
Note! The ”distance effect” reduction
does not apply to Ups margin since the
front-time of a switching surge impulse
is longer.
It is recommended that the protection
margins (after taking into account the
”distance effect”) should be of the order of
20% or more to account for uncertainties
and possible reduction in the withstand
values of the protected equipment with
age.
Should the selected arrester type not
give the desired protection margins, the
selection should be changed to an arrester of a higher line discharge class, which
automatically leads to lower Upl.
Note! Do NOT use a lower-than selected
(Ur) to attempt improve the margins, as
this may lead to unacceptably low TOV
capability.
As an additional assistance in selection,
please refer to the simplified flow chart at
the beginning of this chapter.

External creepage distance
IEC 60815 defines the minimum creepage

conditions. Select the housing to give the
desired creepage - the same as for the
other equipment in the same location. If
the creepage demand exceeds 31 mm/kV,
please refer to ABB for a special design.
to reduce the static loading. Suspending
PEXLIM arresters further reduces the
static terminal loading and allows PEXLIM
arresters to also be chosen for higher
voltages without mechanical problems.
For short arresters, the mechanical
strength of PEXLIM approximately equals
that for EXLIM. For longer arresters, the
lower mechanical strength of PEXLIM arresters can be compensated by using suspended or under-hung erection or by special
bracing for upright erection. For details,
refer to publication PTHVP/A 2120en.

PEXLIM arresters, having a highly
hydrophobic housing, are better suited
for extremely polluted areas than EXLIM
arresters and a lower creepage may be
justified in many cases.
Mechanical strength
The maximum useable static and permissible cantilever loading is shown in the relevant catalogues and summarised in Table 4.

Simplified selection procedure
Neutral-ground arresters
For neutral-ground arresters the recommended rated voltage is approximately
the maximum system voltage divided by
√3. The recommended neutral-ground
arresters in the relevant sections are
calculated for unearthed systems with
relatively long fault duration. The electrical
characteristics are identical to standard
catalogue arresters with the corresponding rated voltage. For such arresters,
Uc is zero and they are not subject to
any voltage stress during normal service
conditions. The neutral-ground arresters
should preferably be of the same type as
the phase-ground arresters. For resonantearthed systems with long radial lines
special considerations must be taken. A
higher rated voltage (20% to 40%) than
listed may be necessary.
Type designation
The type designation itself gives detailed
information of the arrester and its application. See the figure below. As standard,
the arresters are meant for upright vertical
erection. For under-hung erection, when
desired, the type designation is completed
by letter ”H” after system voltage (Um).
For other angular erection, please inform
us at order.

= 0.72x145 = 104.4 kVrms. Select the
next higher standard Ur (see ”Guaranteed protective data”), i.e. 108 kVrms.
2 According to table 2, a common
choice selection for 145 kVrms would
be a line discharge class 2 arrester, i.e.
PEXLIM R. This arrester has a Upl/Ur
of 2.59, i.e. Upl of 280 kVpeak at 10 kA
(according to table 3). With a Uwl of
550 kVpeak this would give a protective
margin of (550/280-1)x100 = 96 %.
3 This margin appears to be excellent
but it must be noted that depending on
distance effect and possible insulation
ageing, the margin is reduced to only
ABB Surge Arresters — Buyer’s Guide
10% to 15% after taking distance effect
into account and depending on the
chosen impulse steepness and amplitude. Thus, it is very important that the
arrester is installed as close as possible
to the protected object.
4 If the margin is considered insufficient,
choose a class 3 arrester, e.g. PEXLIM Q
with the same rated voltage 108 kV.
5 With a required creepage distance of
3 000 mm, i.e. 20.7 mm/kV, YH145
(XH145 for PEXLIM Q) housing should
be selected.

arrester will then be:

Design
Porcelain-housed arrester
Design features - Porcelain-housed arresters, EXLIM
The design is based on successful
experience of over 65 years, first as
gapped SiC arresters, in all climates
and conditions all over the world.
EXLIM arresters live up to their name:
EXcellent voltage LIMiters. The design
is robust and well-matched with the
other apparatus in substations.
Each arrester is built up of one or more
units. Each unit is a porcelain housing
containing a single column of ZnO blocks,
all individually extensively routine-tested
during manufacture, dispersed with the
necessary spacers as determined by
the electrical design for the arrester. It is
necessary, therefore, that the units are
series-connected at site in the pre-determined order as marked on the units. Consult the installation instructions supplied
with each arrester.
Longer arresters often require (and are
supplied with) external grading rings to
maintain a uniform and acceptable voltage
stress along their length. Operation of such
arresters without the grading rings, therefore, may lead to failure and invalidates our
guarantees/warranties.
The standard porcelain colour is brown
but grey porcelain is supplied on request.
Seaworthy packing of the arresters is
standard.

Please see the figures herein.
For satisfactory performance, it is
important that the units are hermetically
sealed for the lifetime of the arresters. The
sealing arrangement at each end of each
unit consists of a pre-stressed stainless
steel plate with a rubber gasket. This
plate exerts a continuous pressure on the
gasket against the surface of the insulator
and ensures effective sealing even if the
gasket ”sets” due to ageing. It also serves
to fix the column of the blocks in the
longitudinal direction by means of springs.
The sealing is verified for each unit after
manufacture in routine tests.
The sealing plate is designed to act also
as an over-pressure relief system. Should
the arrester be stressed in excess of its
design capability, an internal arc is established. The ionised gases cause rapid
increase in the internal pressure, which in
turn causes the sealing plate to flap open
ABB Surge Arresters — Buyer’s Guide
Porcelain-housed arrester
and the ionised gases to flow out through
the venting ducts. Since the ducts at the
two ends are directed towards each other,
this results in an external arc; thus relieving the internal pressure and preventing
a violent shattering of the insulator.
Mechanical Strength
The mechanical strength of the housing,
i.e. maximum permissible dynamic service
load (MPDSL), is defined in accordance
with IEC 60099-4. Thus the fracture
moment is generally 120% of the specified figure. The insulating base (when
supplied) matches the strength of the
housing.
The permissible static service load
(PSSL) i.e. continuous moment should be
limited to 40% of the MPDSL in accordance with IEC 60099-4.
Arresters with mechanical strength
higher than listed are quoted on request.
Design
any special tools or instruments. Properly
chosen and installed arresters are practically maintenance-free for their lifetime
and do not need any monitoring. However, if such monitoring is demanded, it
is easily performed online by using the
EXCOUNT-II with it’s built-in features for
correctly measuring the resistive leakage
current.
Mechanical loading
Horizontal (cantilever) load
The maximum permissible continuous
horizontal load is calculated as the maximum continuous (static) moment divided
by the distance between the base of the
arrester and the centre of the terminal
load.
The continuous current through an
arrester is of the order of a few mA.
Hence, using a lighter terminal clamp
and/or connecting the arrester by a lighter
tee-off considerably reduces the demand
for mechanical strength.

for vertical, upright erection on a structure
and require no bracing. Special EXLIM

Design Highlights
Each arrester is built-up of one or more
units, which in turn may be made up of
one or more modules. Each module
contains a single column of ZnO-blocks,
that are extensively individually routinetested during manufacture, dispersed with
the necessary spacers as determined by
the electrical design for the arrester. The
modules are standardised into different
sizes based on electrical, mechanical and
process considerations.
ABB employs a unique patented
design to enclose the ZnO blocks of each
module under axial pre-compression in
a cage formed of fibreglass reinforced
loops fixed between two yokes which also
serve as electrodes. An aramide fibre is
wound over the loops resulting in an open
cage design for the module. This results
in high mechanical strength and excellent
short-circuit performance. See the figures
hereunder.
Each module is then passed through a
computer-controlled cleaning and priming
process. The module is then loaded in a
highly automated vulcanising press and
silicone injected at a high pressure and
temperature (HTV process) to completely
bond to the active parts, leaving no internal voids or air spaces.
Individual modules are thereafter
assembled into units and routine tested
before packing and dispatch.
For satisfactory performance, it is
important that the units are hermetically
sealed for the lifetime of the arresters. The
HTV moulding process under vacuum
ensures this by bonding along the entire
length from electrode to electrode. There
is no air or any gas entrapped between
the active parts and the housing. Hence,
gaskets or sealing rings are not required.
Should the arrester be electrically stressed in excess of its design capability,
an internal arc will be established. Due
to the open cage design, it will easily
burn through the soft silicone material,
ABB Surge Arresters — Buyer’s Guide
permitting the resultant gases to escape
quickly and directly. At the same time,
the aramide fibres prevent the explosive
expulsion of the internal components.
Hence, special pressure-relief vents are
not required for this design. The fail-safe
short-circuit capability is verified in shortcircuit tests in accordance with IEC.

High strength (HS) PEXLIM tube design
In special cases with very high demands
for mechanical strength, the moulded
design may not provide the optimal solution (particularly at system voltages above
420kV). Instead, what is required is a
mix between the features of the standard
EXLIM and the moulded PEXLIM designs.
The HS (High strength) PEXLIM tube
design provides this by offering comparable mechanical strength to EXLIM
arresters, but with much less mass. The
seismic and pollution performance is in
line with the moulded PEXLIM arresters
and thus superior to conventional porcelain designs.
Design highlights
The basic concept is the replacement of
the porcelain housing used with EXLIM
arresters by a fibreglass tube housing
onto which the silicone sheds are vulcanised. The metal flanges are integrated
onto the tube prior to the vulcanising process. The internal arrangement and the
pressure-relief devices are similar to those
for EXLIM arresters.
For satisfactory performance, it is
important that the units are hermetically
sealed for the lifetime of the arresters.
The sealing arrangement at each end of
each unit is shown in the figure hereunder
and consists of a pre-stressed stainless
steel plate with a rubber gasket. This
plate exerts a continuous pressure on
the gasket against the inner surface of
the flanges and ensures effective sealing
even if the gasket “sets” due to ageing. It
also serves to fix the column of the blocks
in the longitudinal direction by means of
heavy spring washers.
To maintain the interior free of any humidity, the unit is evacuated after the sealing
plate and gaskets are fitted and then filled
with dry air at low dew point. Additionally,
a small bag of a desiccant is placed in
each unit during assembly. Sealing is verified for each unit after manufacture during
routine tests.

The sealing plate is designed to also
act as an over-pressure relief system.
Should the arrester be electrically stressed in excess of its design capability,
an internal arc is established. The ionised gases cause a rapid increase in the
internal pressure, which in turn causes
the sealing plate to flap open and the
ionised gases to flow out through the
venting ducts. Since the ducts at the two

results in an external arc; thus relieving the
internal pressure and preventing a violent
shattering of the insulator. The successful
operation of the pressure-relief device is
verified in short-circuit tests in accordance
with IEC.

Silicone-housed arrester
Design
Silicone as an Insulator
All PEXLIM arresters utilise silicone for
the external insulation. Silicone rubber is
highly hydrophobic and resistant to UV
radiation and has been shown to be the
best insulation (compared to both porcelain and other polymers) based on world
wide independent laboratory and field
tests. ABB uses special fillers to enhance
these properties as well as giving it high
pollution resistance, tracking resistance
and fire-extinguishing features. The
silicone housing is available only in grey
colour. For additional information, please
refer to publications PTHVP 9001en and
PTHVP/A 2120en.
Mechanical Strength
Present standards lack suitable definitions and tests regarding the mechanical
strength of composite polymeric material.
A “damage limit” has nevertheless been
defined in IEC60099-4 as the lowest value
of force perpendicular to the longitudinal
axis leading to mechanical failure. Similarly, the “maximum permissible dynamic
service load” (MPDSL) is the greatest
dynamic force allowed to be applied
during service without causing any
mechanical damage to the arrester.
All PEXLIM designs exhibit very high
strength under tensile or compression
loading; hence it is the cantilever loading
that is of interest. To be applicable to
different arrester lengths, the loading is
given in terms of bending moment in this
guide. Furthermore, since standard multiunit PEXLIM arresters are built with units
of equal strength, the bending moment at
the base of the arrester is the only figure
of interest.
Due to their flexible construction,
PEXLIM arresters may exhibit a visible
deflection at the line-end of the arrester
under maximum loading. Such deflection is limited by our declared value for
permissible static service load (DPSSL)
given in Table 4. This maximum recommended continuous loading ensures that
ABB Surge Arresters — Buyer’s Guide
the electrical and/or mechanical functions
of the arrester are not impaired in any way,
even during long-term cyclic loading. This
value is comparable with the permissible
static service load for porcelain arresters
(PSSL).
If the permissible bending moment
for a certain arrester appears insufficient
for a given loading, consider one of the
following methods to reduce the loading
demand.
• Use lighter terminal clamps and/or lighter tee-offs for arresters. In contrast to
the current capability (and thus the size
of clamps and conductors) required for
other substation equipment, the continuous current through an arrester is
of the order of only a few mA. Hence,
using lighter terminal clamp and/or
connecting the arresters by lighter teeoffs considerably reduce the demand
for mechanical strength.
§ Use another erection alternative (suspension, under-hung, etc). Since
PEXLIM arresters are very light compared to equivalent porcelain-housed
arresters, they permit innovative erection alternatives, which could further
reduce the bending moment demands;
particularly in the case of the moulded design PEXLIM. Refer publication
PTHVP/A 2120en. This in turn can
lead to the additional benefit of lighter
structures with subsequent reduced
costs, or even the complete elimination
of the need for a separate structure at
all.
Pedestal-mounted long arresters with
mechanical strength higher than listed
may be quoted on request.
The line terminal and the insulating base

There are two standard ranges of the

• Vertical & upright erection mounted on
a structure or suspended by the line
terminal from a conductor. Such arresters may also be used for “positive”
angular erection (above horizontal).
• Vertical and inverted erection for mounting under a structure, e.g. a gantry.
Such arresters may also be used for
“negative” angular erection (below horizontal).

be series-connected at site in a predetermined order as marked on the units
and explained in the instructions that are

The design of long arresters often
requires external grading rings to maintain
a uniform and acceptable voltage stress
along their length. Such rings are included
in the delivery of arresters. Installation or
operation of such arresters without these
grading rings may lead to failure and invalidates our warranty.

The PEXLINK concept

utility owners of transmission systems face a sharpened competitive
situation which demands increased
availability and reliability of the systems. Consumers have become more
demanding as their processes are
dependent on constant and reliable
energy supply of good quality.
events. Surge arresters installed along the
line or at a few selected critical towers, in
this case, may be an attractive solution or
a complement to other means.
Improvement in the reliability and
availability of a transmission system
can be obtained in one or more of the
following ways:
1. Duplication of the system (more than
one line).
This is a very expensive method and often
impractical.
2. Increased insulation withstand.
It can both be expensive and create other
problems such as the need for increased
insulation of station equipment.
3. Improved footing impedance.
Often difficult and expensive, specially in
hilly terrain.
4. Shield wires.
If the provision was not in the original
tower design, it can be expensive to
retrofit such shielding. It helps eliminate
a large number of interruptions but it is
not enough to obtain the now-demaded
degree of reliability
5. Protection of line insulation by
surge arresters
Picture shows a TLA for 145 kV, comprising
standard components including PEXLIM arrester and EXCOUNT-II monitor.
In many countries, it has also been
increasingly difficult to obtain permission
to build new lines of normal dimensions.
Hence, new lines under construction may
mostly be ”compact-insulation” lines. This,
in turn, requires optimal control of overvoltages caused by lightning or switching
ABB Surge Arresters — Buyer’s Guide
Surge arresters connected in parallel with
them at selected towers. In this application usually the term line arresters is
used. Protection using polymer-housed
arresters (ABB type PEXLIM) along with
additional accessories for fixing the arresters across the insulators and providing
automatic disconnection of the arresters
in the event of their being overstressed is
called the PEXLINK concept. This method
is simple, cost-effective and, in many
cases, an attractive alternative to the methods mentioned above.

ABB´s protection philosophy
ABB’s philosophy is to provide protection for line insulation at selected
locations by using standard available
components. The main item is the
gapless silicone polymer-housed arrester, PEXLIM, with metal-oxide (MO)
active elements. Such arresters have
been used for many years for protection of equipment in substations and
hence their protective performance is
well-known.

chosen locations.
The design permits installation using
standard transmission-line hardware
normally available locally. The design
also permits mounting at different angles
based on tower geometry and conductor
spacing.
If very high availability is desired, a very
large number of locations may have to be
protected, mainly due to the unpredictable nature of lightning. In such a case it
The low weight permits installation on
existing structures and the polymer
housing gives increased safety of the line
equipment as well as people and animals
which may be in the vicinity of the lines
during overstress conditions.
With regard to lightning energy, line
arresters are exposed to more severe
conditions than arresters placed in substations. The latter are benefited by the
reduction of surge steepness due to line
corona effect and reduction in surge amplitude as the lightning current finds parallel
paths through shielding wires, flashover
and parallel lines. Thus, it is necessary to
ensure that the MO blocks of the TLA are
not under-dimensioned from energy and
current point-of-view. A computer program is used to determine the optimum
number of locations (generally where the
footing impedance is high) and to calcu-
may not be economically justified to select
arresters with ”sufficient energy capability”
and instead a higher failure rate may be
acceptable.
To ensure quick, safe, automatic and
controlled disconnection of a failed arrester, ABB uses a special disconnecting
device with a suitable link, often in the
earthing circuit of the arresters.
The earth lead is designed to withstand
the short-circuit currents and the disconnecting device is tested to ensure no
false operations. Thus, at a failure, the
tripped line does not have to be lockedout and attended to immediately.
By moulding the silicone polymer housing on the active MO elements directly,
internal atmosphere is eliminated and with
it the risk of ingress of moisture which
in the past has been established as the
major cause of arrester failures in service.

PEXLINK
Application
Increased line availability
By locating the PEXLINK on sections of
lines with high footing impedance towers
and one additional low footing-impedance
tower at each end of the section, PEXLINK
protects existing shielded and non-shielded
lines from abnormal lightning surges (frequent or high amplitudes) and reduces the
outages.
The reduced outages are beneficial also
indirectly in that sensitive equipment is not
damaged and the circuit breakers overhaul interval can be increased. Thus, total
maintenance costs are also reduced.
This protection may be used for all system
voltages where the stated abnormal
conditions exist. Arresters with moderate energy capability are often sufficient.
However, the high-current capability must
be large and distribution-type arresters
may not be suitable.
For long EHV lines, surge arresters usually are located at line-ends. In addition,
by locating arresters at one or more
points along the line e.g. at midpoint or
1/3 and 2/3 line length switching surge
overvoltages and thus line insulation
requirements could be limited without
using preinsertion resistors. Arresters
used for this type of application should
be designed for high energy capability. Usually a class 2 or 3 arrester will
be sufficient out on the line but higher
arrester classes may be necessary at
the receiving end of the line.
Compact-insulation lines
Arresters placed in parallel with line insulators permit a large degree of compacting
of a transmission line with lower right-ofway costs as a result.
No overvoltage control

alternative, could be located at line ends
and along the line at selected points.

Application
Line upgrading
The existing insulation level of a line, when
suitably protected by arresters, may be
upgraded for service at a higher system
voltage leading to greater power transfer
without much additional capital cost.
Extended station protection
By locating arresters on towers near a substation, the risk of backflashovers near the
station is eliminated. This results in reduction of steepness and amplitude of incoming travelling waves, thus improving the
protection performance of station arresters
and eliminating the need for additional
expensive metal-enclosed arresters even
for large GIS.

Substitute for shield wires
In cases where provision of shield wires is
not practical physically or is very expensive, e.g. very long spans, very high
towers etc., arresters are a good and
economical substitute.
Arresters located in all phases on each
tower eliminate the need for both shield
wires and good footing impedance and
may be economically justified in cases
where the cost of reduction in footing
impedance and the cost of overhead
shield wire are very high.

The separation of the disconnector
is quick and effective and the method
of connection advised by ABB in each
particular case ensures that neither the
disconnected wire nor the damaged

live parts. Thus, after a failure, the line
can be re-charged without attending to it
immediately.

Guaranteed residual voltage
The residual voltage at 10 kA, 8/20 µs
impulse current of each unit is calculated
as the sum of the residual voltages for all
blocks connected in series in the unit.
The residual voltage of the complete
arrester is the sum of the residual voltages
for its units.
Tightness check (only for EXLIM arresters)
It is performed by placing each unit in a
vacuum chamber connected to a Hespectrometer. Maximum permissible
leakage is 0.00001 mbarl/s at a pressure
difference of 0.1 MPa.
Power frequency reference voltage
Reference voltage is measured on each
arrester unit.
Internal corona
It is checked on each unit at 0.9 times Ur.
A steady internal corona level less than
5 pC is required in a pass/no-pass test.
Grading current
It is measured at Uc on each unit.
Power losses
They are measured at Uc on each unit
verifying that the thermal performance is in
compliance with performed type tests.
Test reports
Routine test reports are filed and are
available on request. The reports include
reference voltages, power losses and
residual voltages.
Tests on accessories
Surge counters, EXCOUNT-A
All counters are routine-tested in a pass/
no-pass test before leaving the factory.

More detailed information on the TOV capability and the protective characteristics are given in Publ. 1HSM 9543 13-01en.
1) The continuous operating voltages Uc (as per IEC) and MCOV (as per ANSI) differ only due to deviations in type test procedures.
Uc has to be considered only when the actual system voltage is higher than the tabulated.
Any arrester with Uc higher than or equal to the actual system voltage divided by √3 can be selected.
2) With prior duty equal to the maximum single-impulse energy stress (2.5 kJ/kV (Ur)).
3) Arresters for system voltages 36 kV or below can be supplied, on request, when the order also includes arresters for higher system voltages.
Arresters with lower or higher rated voltages may be available on request for special applications.

Protection of switchgear, transformers and
other equipment in high voltage systems
against atmospheric and switching
overvoltages.
• in areas with high lightning intensity
and high energy requirements.
• where grounding or shielding condi-
tions are poor or incomplete
Superior where low weight, reduced
clearances, flexible mounting,
non-fragility and additional personnel
safety is required.
Major component in PEXLINKTM concept for transmission line protection.

More detailed information on the TOV capability and the protective characteristics are given in Publ. 1HSM 9543 13-01en.
1) The continuous operating voltages Uc (as per IEC) and MCOV (as per ANSI) differ only due to deviations in type test procedures.
Uc has to be considered only when the actual system voltage is higher than the tabulated.
Any arrester with Uc higher than or equal to the actual system voltage divided by √3 can be selected.
2) With prior duty equal to the maximum single-impulse energy stress (4.5 kJ/kV (Ur)).
3) Arresters for system voltages 36 kV or below can be supplied, on request, when the order also includes arresters for higher system voltages.
Arresters with lower or higher rated voltages may be available on request for special applications.

More detailed information on the TOV capability and the protective characteristics are given in Publ. 1HSM 9543 13-01en.
1) The continuous operating voltages Uc (as per IEC) and MCOV (as per ANSI) differ only due to deviations in type test procedures.
Uc has to be considered only when the actual system voltage is higher than the tabulated.
Any arrester with Uc higher than or equal to the actual system voltage divided by √3 can be selected.
2) With prior duty equal to the maximum single-impulse energy stress (7.0 kJ/kV (Ur)).
3) Arresters for system voltages 36 kV or below can be supplied, on request, when the order also includes arresters for higher system voltages.
Arresters with lower or higher rated voltages may be available on request for special applications.

More detailed information on the TOV capability and the protective characteristics are given in Publ. 1HSM 9543 13-01en.
1) The continuous operating voltages Uc (as per IEC) and MCOV (as per ANSI) differ only due to deviations in type test procedures.
Uc has to be considered only when the actual system voltage is higher than the tabulated.
Any arrester with Uc higher than or equal to the actual system voltage divided by √3 can be selected.
2) With prior duty equal to the maximum single-impulse energy stress (7.0 kJ/kV (Ur)).
Arresters with lower or higher rated voltages may be available on request for special applications.

Each crate contains a certain number of arrester units
and accessories for assembly and erection. A packing list is attached externally on each crate.
Each separate crate is numbered and the numbers
J-7
of all crates and their contents are listed in the shipping
specification. ABB reserves the right to pack arresters in
the most effective/economic combination. Alternate or
non-standard crates may involve additional charges.

More detailed information on the TOV capability and the protective characteristics are given in Publ. 1HSM 9543 13-01en.
1) The continuous operating voltages Uc (as per IEC) and MCOV (as per ANSI) differ only due to deviations in type test procedures.
Uc has to be considered only when the actual system voltage is higher than the tabulated.
Any arrester with Uc higher than or equal to the actual system voltage divided by √3 can be selected.
2) With prior duty equal to the maximum single-impulse energy stress (7.0 kJ/kV (Ur)).
Arresters with lower or higher rated voltages may be available on request for special applications.

Protection of switchgears, transformers
and other equipment in high voltage systems against atmospheric and switching
overvoltages.
• in areas with very high lightning intensity
• where grounding or shielding conditions
are poor or incomplete
• for important installations
• where energy requirements are very
high (e.g. very long lines, capacitor
protection).
• Specially suited to high seismic
applications.
Superior where low weight, non-fragility
and additional personnel safety is required.

More detailed information on the TOV capability and the protective characteristics are given in Publ. 1HSM 9543 13-01enen.
1) The continuous operating voltages Uc (as per IEC) and MCOV (as per ANSI) differ only due to deviations in type test procedures.
Uc has to be considered only when the actual system voltage is higher than the tabulated.
Any arrester with Uc higher than or equal to the actual system voltage divided by √3 can be selected.
2) With prior duty equal to the maximum single-impulse energy stress (2.5 kJ/kV (Ur)).
3) Arresters for system voltages 36 kV or below can be supplied, on request, when the order also includes arresters for higher system voltages.
Arresters with lower or higher rated voltages may be available on request for special applications.

More detailed information on the TOV capability and the protective characteristics are given in Publ. 1HSM 9543 13-01enen.
1) The continuous operating voltages Uc (as per IEC) and MCOV (as per ANSI)) differ only due to deviations in type test procedures.
Uc has to be considered only when the actual system voltage is higher than the tabulated.
Any arrester with Uc higher than or equal to the actual system voltage divided by √3 can be selected.
2) With prior duty equal to the maximum single-impulse energy stress (4.5 kJ/kV (Ur)).
3) Arresters for system voltages 36 kV or below can be supplied, on request, when the order also includes arresters for higher system voltages.
Arresters with lower or higher rated voltages may be available on request for special applications.

More detailed information on the TOV capability and the protective characteristics are given in Publ. 1HSM 9543 13-01enen.
1) The continuous operating voltages Uc (as per IEC) and MCOV (as per ANSI)) differ only due to deviations in type test procedures.
Uc has to be considered only when the actual system voltage is higher than the tabulated.
Any arrester with Uc higher than or equal to the actual system voltage divided by √3 can be selected.
2) With prior duty equal to the maximum single-impulse energy stress (4.5 kJ/kV (Ur)).
3) Arresters for system voltages 36 kV or below can be supplied, on request, when the order also includes arresters for higher system voltages.
Arresters with lower or higher rated voltages may be available on request for special applications.

More detailed information on the TOV capability and the protective characteristics are given in Publ. 1HSM 9543 13-01enen.
1) The continuous operating voltages Uc (as per IEC and MCOV (as per ANSI) differ only due to deviations in type test procedures.
Uc has to be considered only when the actual system voltage is higher than the tabulated.
Any arrester with Uc higher than or equal to the actual system voltage divided by √3 can be selected.
2) With prior duty equal to the maximum single-impulse energy stress (7.0 kJ/kV (Ur)).
3) Arresters for system voltages 36 kV or below can be supplied, on request, when the order also includes arresters for higher system voltages.
Arresters with lower or higher rated voltages may be available on request for special applications.

More detailed information on the TOV capability and the protective characteristics are given in Publ. 1HSM 9543 13-01enen.
1) The continuous operating voltages Uc (as per IEC and MCOV (as per ANSI) differ only due to deviations in type test procedures.
Uc has to be considered only when the actual system voltage is higher than the tabulated.
Any arrester with Uc higher than or equal to the actual system voltage divided by √3 can be selected.
2) With prior duty equal to the maximum single-impulse energy stress (10.0 kJ/kV (Ur)).
Arresters with lower or higher rated voltages may be available on request for special applications.

Surge Arrester Monitor EXCOUNT-II
As businesses strive to remain competitive, improved reliability of electricity
supply and reduced maintenance costs
are demanded by both power utilities
and users alike.
ABB has in response developed
EXCOUNT-II; an advanced surge arrester monitor for effectively, reliably and
safely monitoring and recording surges
on high voltage electrical
networks.
More than just a counter
Discharge operation counters have been
available for use with surge arresters for
many years, however these have lacked
the ability of giving a direct indication of
the true health of surge arresters. Even
counters fitted with simple mA meters
are of very limited use, as they are unable
to differentiate between the internal and
external leakage currents nor exclude
harmonic effects.
EXCOUNT-II is an entirely new
monitoring system, as it can be used as
an aid to assess the health of the entire
substation by monitoring surges transmitted in and out of the network. The
device is fitted to surge arresters within
a substation similar to normal counters,
but in addition to counting the number
of discharges, EXCOUNT-II also records
the amplitude of the surges, together with
their date and time, plus measures the
total leakage current and (optionally) resistive current through the arrester.
The measurements are stored in the
EXCOUNT-II sensor, and can be collected
when convenient with the aid of a handheld cordless transceiver. The raw data
is then transferred over to a computer for
statistical analysis.
The detailed results obtained from
EXCOUNT-II are not limited to a simple
estimation of arrester stresses but instead
give a true indication of the number and
severity of surges and, when combined
with data from event recorders, SCADA,
etc, facilitiates an effective analysis of the
amount and degree of voltage stress all
equipment in the substation have been
subjected to.
Unique data acquisition method
EXCOUNT-II is unique in its method of
acquiring data. Each surge arrester is
fitted with a sensor, which detects the
total number of discharges, the surge
amplitude, date and time of occurrence,
as well as the leakage current through the
arrester. All data is stored in the sensor’s
memory, and can then be read when
convenient with the aid of a hand-held
transceiver.
EXCOUNT-II´s measurement method is
unique and simple.
The sensor´s measured data is cordlessly
transferred to a hand
held transceiver. The
measured data from
the transceiver can
then be transfered
to a computer for
statistical analysis.

Remote reading
Every sensor has a unique identity. Via the
hand-held transceiver, the user selects the
identity of the sensor he is interested in
interrogating and communication will then
be established directly with that sensor.
The operator may take data from sensors
in the substation within a distance of 60 m
from where he is standing, and up to 30
sensors can be interrogated in one and
the same session.
Remote reading leads to increased personnel safety compared with conventional
counter reading. Indeed, the person does
not necessarily have to even be inside the
substation perimeter, so saving the need
to arrange entry permits or have electrically trained personnel perform the work.
Surge counting
EXCOUNT-II does more than just count
surges. It also registers the date and time
as well as amplitude of the surge each
time the arrester has discharged a current
over 10 A. Time and amplitude measurement gives the user better information
about overvoltages in the network and the
operation of the arrester.
Leakage current measurement
and condition monitoring
EXCOUNT-II gives the user the possibility
to measure both the total leakage current
as well as the resistive component of the
current through the arrester. Measurement
of the resistive current gives a good indication of the arrester’s condition. The measurement method employed is based on
third-harmonic analysis of the leakage current, and is the same as that used with the
LCM (Leakage Currrent Monitor) which is
internationally well proven since 1989. This
is considered the most reliable measuring
method for condition monitoring according
to IEC 60099-5.
Statistical analysis
Included with EXCOUNT-II is
specially designed software which facilitia-
ABB Surge Arresters — Buyer’s Guide
EXCOUNT-II
tes download of the measured data from
the transceiver and permits analysis and
reporting of the collected information.
The included program is easy to use
with a standard MS
Windows interface,
and gives details
about over-voltages
in the network as
well as the surge
arrester´s condition.
Maintenance free
The sensor is housed in a sealed,
weather-proof case, suitable for outdoor
use and proven to match the shortcircuit capability of the arrester. The
sensor requires no external power supply
as it incorporates its own internal power
supply in the form of a solar cell, field
probe and capacitor. For indoor use, the
sensor may be alternatively powered by a
standard 9 volt battery.
Flexibility
EXCOUNT-II is available in two different
versions. Both versions measure surge
currents (number, amplitude and time)
as well as total leakage current. The full
version additionally measures the resistive
component of leakage current.
Simple installation
EXCOUNT-II surge monitoring system
incorporates a sensor, which is mounted
on the arrester, a transceiver, for remote
reading, and a PC-program (Windows 95/
98/ME/XP and NT/2000). The system is
easy to install on both existing and newly
purchased surge arresters fitted with an
insulating base.

Surge Counter EXCOUNT-A
Highest personnel safety
• Explosion-proof for short-circuit currents
up to 80 kA.
• Same safe performance as arresters.
Negligible residual voltage
• Does not reduce protection margins.
• Reduces risk against accidental contact
during surges.
Long life
• Moulded components, non-sensitive to
humidity or temperature variations.
• Verified by tests per IEC 60068.
Universal application
• All makes and types of surge arresters.
• All weather and temperature conditions.
For gapless surge arresters, surge counters are used only to obtain information
regarding surge activities in the corre
sponding surge arrester and its location.
Surge counter, EXCOUNT-A is designed
therefore, to withstand the same severe
conditions as the arresters without failure.
Design features
EXCOUNT-A comprises basically of an
impulse current transformer with a singleturn primary in the form of an insulated
stranded-copper cable to be connected in
the earth circuit of an arrester. The cable is
provided at both ends with tinned-copper
cable shoes.
The secondary circuit consists of a rectifier, capacitor and an electronic switch
connected to a mechanical counting relay
and is totally moulded in plastic which
makes it ideal for exposed installation. The
complete assembly is the housed in an
elegant vented aluminium casing. A suitable-angled window permits easy reading
of the 6-digit cyclometer-typ counter.
S-1
Edition 4, 2003-10
The principle of operation is shown in
figure 1 on next page.
Performance
The design of the secondary circuit ensures that the counting relay is not energised
for low lightning current impulses which
are insignificant to the arrester capability
and life. The stepping criteria are given in
figure 2 on next side. The current transformer secondary output is sufficient for
driving the counter and external supply
source is not needed.
The single-turn primary ensures that the
voltage drop across the counter, even at
the highest impulse currents encountered
in service, is negligible, leading to added
personnel safety and no increase in the
protection level of the arrester.
Since no gaps or series impedance
are used, there is no risk of internal
arcing and consequent explosive faillure
in the event of a short-circuit following
an arrester failure.

At 65 kA, there were no damages at all.
At 80 kA, the insulation of the primary
conductor was burnt.
However, the counter function was not
impaired and no pieces were ejected.
All surge counters are routine-tested
with a sufficient number of impulses in a
pass/no pass test prior to despatch from
the factory.
Packing, installation and
maintenance
Counters are packed in cases together
with arresters. For separate supply, they
are packed in cartons.
Detailed instructions are enclosed with
each counter. However, the following may
be noted.
The counter must be placed at a suit
able height for easy reading. The electrical lead between the earth terminal and
the counter should be insulated and its
length kept to a minimum. If the length is
too long, the counter may not register for
very steep impulses when the inductive
voltage between the earth terminal and
the counter exceeds the lightning impulse
withstand level of the insulating base.
The counters are maintenance-free.
Refer to assembly instructions for
more details.
