Definitions
Maximum system voltage (Um)The max. voltage between phases during normalservice.
Nominal discharge current (IEC)The peak value of the lightning current impulse, whichis used to classify the arrester.
Lightning classifying current (ANSI/IEEE)The designated lightning current used to perform theclassification tests.
Rated voltage (Ur)An arrester fulfilling the IEC standard must withstandits rated voltage for 10 s after being preheated to 60 °Cand subjected to energy injection as defined in thestandard. Thus, Ur shall equal at least the 10 s TOVcapability of an arrester. Additionally, rated voltage isused as a reference parameter. Note! TOV capability of PEXLIM arresters exceedsthe IEC requirements.
Continuous operating voltageIt is the max. permissible rms power frequencyvoltage that may be applied continuously between thearrester terminals. This voltage is defined in differentways (verified by different test procedures) in IEC andANSI/IEEE.
IEC (Uc)IEC gives the manufacturer the freedom to decide Uc.The value is verified in the operating duty test. Anyuneven voltage distribution in the arrester shall beaccounted for.
ANSI/IEEE (MCOV)ANSI/IEEE lists the maximum continuous operatingvoltage (MCOV) for all arrester ratings used in a table.The value is used in all tests specified by ANSI/IEEE .MCOV is less stringent as regards uneven voltagedistribution in an arrester.
Temporary overvoltages (TOV)Temporary overvoltages, as differentiated from surgeovervoltages, are oscillatory power frequency over-voltages of relatively long duration (from a few cyclesup to hours).The most common form of TOV occurs on the healthyphases of a system during an earth-fault involving oneor more phases. Other sources of TOV are load-rejection, energisation of unloaded lines etc.The TOV capability of PEXLIM Q arresters is indi-cated with/without prior energy stress. Refer to Publ.SESWG/A 2227en.
Residual voltage Discharge voltage (Ures )This is the peak value of the voltage that appearsbetween the terminals of an arrester during thepassage of discharge current through it. Uresdepends on both the magnitude and the waveformof the discharge current. Complete V/I curves areshown in Publ. SESWG/A 2227en.
Energy capabilityStandards do not explicitly define energy capabilityof an arrester. The only measure specified is theLine Discharge Class in IEC. Often, this may not beenough information to compare different manu-facturers and, therefore, ABB presents energy capa-bility 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 inthe switching surge operating duty test (cl. 7.5.5.)while remaining thermally stable thereafter againstthe specified TOV and Uc . For PEXLIM Q arrestersthis value is 7.4 kJ/kV(Ur )
Routine test energyThis is the total energy which each individual block issubjected to in our production tests. For PEXLIM Qblocks, this value is not less than 5.6 kJ/kV(Ur).
Single-impulse energyThis is the max. permissible energy which an arrestermay be subjected to in one single impulse of 4 msduration and remain thermally stable against specifiedTOV and Uc . For PEXLIM Q arresters this value is4.5 kJ/kV(Ur). Note! Corresponding values based on Uc are obtainedby multiplying the above figures by the ratio Ur /Uc .
Short-circuit capabilityThis is the ability of an arrester, in the event of anoverload due to any reason, to conduct the resultingsystem short-circuit current without violent shatteringwhich may damage nearby equipment or injurepersonnel.After such an operation, the arrester must bereplaced. The system short-circuit current may behigh or low depending on the system impedance andearthing conditions. Hence the short-circuit capabilityis verified at different current levels. Note! PEXLIM arresters are tested with short-circuitinitiated by overvoltage in accordance with proposedamendment 2, IEC 60099-4, which is more stringentfor polymer-housed arresters, than present standards.

Design
ABB employs a unique patented designto enclose the ZnO blocks of eachelectrical unit (often called a �module�)under pre-compression in a cage formedof glass-fibre reinforced loops. Thisresults in high mechanical strength.
Silicone rubber is directly moulded on to the cage,sealing the active elements completely. Since there isno air inside the module, internal partial discharge isavoided. Gaskets are not required to maintain goodsealing. The design also results in excellent short-circuit capability.Silicone rubber is highly hydrophobic and resistantto UV radiation and has been shown to be the bestinsulation (compared to both porcelain and other poly-mers) based on world-wide independent laboratoryand field tests. ABB uses special fillers to enhancethese properties as well as giving it high pollutionresistance, tracking resistance and fire-extinguishingfeatures.Each arrester unit is pre-assembled at our factoryand should not be disassembled for any reason. As inthe case of porcelain-housed arresters, multi-unitarresters are assembled at site.
Short-circuit capabilityAt overload conditions leading to failure of an arrester,the internal pressure is quickly and safely reduced bypuncture of housing, thanks to the special open-cagedesign. Hence, special devices are not required forrelief of internal pressure and personnel/equipmentsafety is excellent.The inherent design of the arresters with siliconepolymer housing directly moulded on the active parts,as in PEXLIM arresters, tends to limit the firstasymmetrical peak current to less than 2.5 times thesymmetrical test current despite the test circuit beingadjusted for this value for a short-circuit test. This isspecially the case for longer units. The matter is underconsideration in IEC to permit a lower asymmetry factorfor such cases since in a real failure situation thisperformance of the polymer-housed arrester would bebeneficial.
Pollution level Creepage in mm/kV (Um)
Light (L) 16Medium (M) 20Heavy (H) 25Very Heavy (V) 31
External insulationExternal insulation withstand strength of an apparatusis the max. value of the voltage (of a given waveshape) that can be applied without external flashover.Surge arresters, whose primary function is to limitovervoltages in other equipment, will obviously be thebest protected of all.The voltage across an arrester can never be higherthan that given by its protective characteristics. Onlythe need for an additional safety factor, includingcorrection factor for installation altitude, can justifytechnically a higher external insulation strength.All PEXLIM surge arresters fully comply with therequirements stated in IEC and ANSI standards foraltitudes up to 1 000 m above sea level.
Field distributionThe module lengths are chosen to ensure low anduniform radial stress on the arrester even under highlypolluted conditions. For longer arresters, axial fielduniformity is ensured by grading rings.
Mechanical strengthPresent arrester standards lack suitable definitions andtests regarding the mechanical strength of polymericarresters. Hence, to guide the user, ABB has intro-duced the term �Max. usable bending moment�, definedas under. Max. usable bending moment is the max.bending moment (in Nm) at the base of a surge arresterresulting from the vector sum of all possible forces (e.g.due to line conductor load, the normal wind load andthe arrester weight) in the direction perpendicular to thearrester axis. This value should be compared with themaximum continuous bending moment of porcelainarresters (typically 40% of the minimum fracturemoment as per DIN standards).
Due to its flexible construction, there may be a visibledeflection at the line-end of the arrester undermaximum loading. Such deflection is limited by ourchoice of the usable bending moment figure as givenin this catalogue which ensures that the electrical and/or mechanical functions of the arrester are notimpaired in any way.
Classification as per IECDifferent levels of pollution are classified in IEC 60815with minimum creepage distances being specified foreach class as under:
HousingCreepage distance and pollution performanceThe creepage distance is the distance measuredalong the insulators external profile and may beinterpreted as a measure of the arrester performancein polluted environments with respect to risk ofexternal flashover.The shed profile comprises alternate long-short shedsin accordance with IEC 60815.

Selection of arrester
Type designationThe type designation gives detailed information of thearrester and its application. See example below.As standard, the arresters are meant for upright verticalerection. For under-hung erection, when desired, thetype designation is completed by letter �H� after systemvoltage (Um). For other angular erection, please informus at order.

For under-hung arresters,letter �H� to be added here
For non-standard arresters, the type designation will haveadditional letters.The most important parameters for proper selection are:- The max. system voltage (Um) at the arrester location- Amplitude and duration of TOV; e.g. based on system grounding and short-circuit duration- Energy requirements- Desired margin of protection or LIPL and SIPL- Creepage and/or pollution level
Selection is simplified by reference to ABB Selectionguide, SESWG/A 2300E and/or by intimating details asper enquiry form SESWG/A 2406E (available at yournearest ABB office) to us.
Ordering dataWe recommend that the same form, SESWG/A 2406E,be filled-in and sent to us with your order, to ensureinclusion of all important parameters and commercialterms and conditions. The information must include atleast:- Quantity and type designation of arrester- Rated voltage of arrester- Type of line terminal- Type of earth terminal- Type of insulating base (if required)- Quantity and type of surge counter- Routine test report, if desired

MountingThe low weight and the high personnel safety permitsthe arrester to be mounted at any angle provided thatmaximum usable bending moment is not exceeded.Thus, they are ideal for use in locations where space islimited (e.g. in cubicles, on transformer tanks andbreaker poles etc.) and for protection of transmissionlines. For inverted mounting and when the angle ofinstallation exceeds 45° under the horizontal plane, weneed to be informed at order to ensure a correct design.
Installation and maintenanceArresters are very easy to install and do not need anyspecial tools or instruments. Installation instructionsare packed in each case.A properly chosen and installed arrester is practicallymaintenance-free for its lifetime. If, for any reasonhowever, monitoring of the arrester condition in serviceis desired, the same is best carried out by a specialportable instrument, ABB type LCM, which measuresthe internal resistive leakage current after filtering allother current components. ABB does not recommendthe use of a simple mA-meters (usually built-in in surgecounters) as such instrument cannot differentiatebetween the internal and external leakage current aswell as other components and harmonics.Note also that operation of arrester without gradingrings, where supplied, may lead to failure andinvalidates our guarantees.

Neutral ground arresters
System voltage range 52 - 170 kVThe neutral-ground arresters should preferably be of thesame type as the phase-ground arresters.For fault clearing times less than 30 minutes, select arated voltage greater than Um/√3 from the table below.For longer fault clearing times, or for resonant earthed
systems with long radial lines, special considerationsmust be taken with regards to rated voltage, creepagedistance, etc. In such cases please contact ABB.The electrical characteristics of the neutral-groundarresters are identical to the standard phase-groundarresters having the same rated voltage, see table�guaranteed protective data� on page 6.

Quality control and testing
ABB Switchgear is certified by BVQI tofulfil the requirements of ISO 9001.
Type testsType (design) tests have been performed in accord-anceboth with IEC 60099-4 and proposed amendment 2 aswell as ANSI/IEEE C62.11. Test reports are available onrequest.
Routine testsRoutine tests are performed on ZnO blocks as well ason assembled arrester units and accessories. The mostimportant type tests data is verified on all batches ofZnO blocks, thus verifying catalogue data.
Tests on ZnO blocksEnergy withstand test on all blocksThe blocks pass three energy test cycles with coolingin-between. In each cycle the injected energy is far inexcess of the single impulse energy capability. Blockswith insufficient energy capability are automaticallyrejected.
Classification of all blocksThe blocks are classified at 1 mA (d.c.) and 10 kA (8/20 µs)and the residual voltages are printed on each blocktogether with a batch identification. Finally all blocks arevisually inspected.
Accelerated life tests on samplesPower losses after 1000 hours calculated from a testwith shorter duration (approx. 300 hours) at an elevatedtemperature of 115°C at 1.05 times Uc shall not exceedthe losses at start of the test. Batches in whichunapproved blocks appear are rejected.
Impulse current tests on samplesBlocks are subjected to high current impulses (4/10 µs)and long duration current impulses (2 500 µs) ofamplitudes verifying catalogue data.
Other sample testsIn addition to the above, low current characteristics,protection characteristics and capacitance are checkedon samples.
Tests on assembled mechanical unitsRoutine tests on units fulfil the demands of both IEC60099-4 and ANSI/IEEE C62.11. Each arrester unit hasa serial number as per IEC 60099-4
Guaranteed residual voltageThe residual voltage at 10 kA, 8/20 µs impulse currentof each unit is calculated as the sum of the residualvoltages for all blocks connected in series in the unit.The residual voltage of the complete arrester is the sumof the residual voltages for its units.
Power frequency reference voltageIs measured at reference current (of 2 mA crestresistive) on each unit.
Internal coronaIs checked on each unit at 0.9 times Ur. A steadyinternal corona level less than 5 pC is required in apass/no-pass test.
Grading currentIs measured at Ucon each unit.
Power lossesAre measured at Uc on each unit verifying that thethermal performance is in compliance with performedtype tests.
Test reportsRoutine test reports are filed and are available onrequest. The reports include reference voltages, powerlosses and residual voltages.
Tests on accessoriesSurge counters, EXCOUNTAll counters are routine-tested in a pass/no-pass testbefore leaving the factory.
Environmental standardsProduction and disposal of our surge arresters isenvironmentally friendly and fulfils the stipulations ofISO 14001.Further information is available on request.
