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. Strong focus on quality 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 clientspecific 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.

ABB Surge Arresters — Buyer’s Guide Edition 5.1, 2007-04 A-2 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 5, 2004-10 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 8.5.5. This is the energy that the arrester is subjected to in the switching surge operating duty test (clause 8.5.5.) 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) ABB Surge Arresters — Buyer’s Guide Edition 5.1, 2007-04 B-2 Definitions Definitions — Transmission Line Arresters 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 damage and without loss of thermal stability. The capability is different for different types and duration of impulses. Isokeraunic level Number of annual thunderstorm days for a given region. B-3 Shielding Edition 5.1, 2007-04 Occur when lightning strikes a transmission line span and a high current surge is injected on to the struck conductor. The impulse voltage and current waves divide and propagate in both directions from the stroke terminal at a velocity of approximately 300 meters per microsecond with magnitudes determined by the stroke current and line surge impedance. ABB Surge Arresters — Buyer’s Guide Selection of arrester Simplified selection procedure 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. System/arrester parameters Vocabulary Um Maximum system voltage Uc Continuous operating voltage Ups Switching impulse protective level Ur Rated voltage Upl Lightning impulse protective level Uws Switching impulse withstand level Uwl Lightning impulse withstand level TOV Temporary overvoltage T TOV strength factor ABB Surge Arresters — Buyer’s Guide k Earth fault factor Edition 5.1, 2007-04 C-1 Selection of arrester Flowchart for simplified selection of surge arresters C-2 Edition 5.1, 2007-04 ABB Surge Arresters — Buyer’s Guide 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. ABB Surge Arresters — Buyer’s Guide System Earthing Fault Duration System Voltage Um (kV) Min. Rated Voltage, Ur (kV) Effective Effective Non-effective ≤1s ≤1s ≤ 10 s ≤ 100 ≥ 123 ≤ 170 Non-effective Non-effective ≤2h >2h ≤ 170 ≤ 170 ≥ 0.8 x Um ≥ 0.72 x Um ≥ 0.91 x Um ≥ 0.93 x Um (EXLIM T) ≥ 1.11 x Um ≥ 1.25 x Um Table 1. 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.

Energy capability of ABB arresters: The normal application range is only a guide. Arresters for higher class may be required depending on the specific parameters. Edition 5.1, 2007-04 C-3 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. 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. Arrester Type Nom.

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 5.1, 2007-04 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. ABB Surge Arresters — Buyer’s Guide Selection of arrester Matching the mechanical characteristics The varistor column must be suitably housed to withstand long-term effects of the system loading and the environmental stresses. External creepage distance IEC 60815 defines the minimum creepage distances for different environmental 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. Mechanical test of silicone-housed arrester PEXLIM P. 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.

C-5 Selection of arrester 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. For non-standard arresters, the type designation will have additional letters for example: E M P Non-standard electrical data Non-standard mechanical data Parallel metal-oxide columns Block-type Ur Internal code For under-hung arresters, letter ”H” to be added here.

Ordering data for arresters The following information, at a minimum, is required with your order: • Quantity and type designation • Rated voltage • Type of line terminal • Type of earth terminal • Type of surge counter, if any • Type of insulating base, if any. (Insulating base is required if surge counter and/or leakage current measurements are desired. One base is required for each arrester).

We recommend that the order form, in section T-1, be filled-in and attached to your order to ensure inclusion of all the important parameters and commercial conditions. ABB Surge Arresters — Buyer’s Guide Selection of arrester Simple selection example Substation data: Maximum system voltage: Arrester location: System earthing: System fault clearance time: Creepage distance: 145 kV Phase-ground Effective 1s 3 000 mm 1 Ur0 = 0.72xUm (according to table 1) = 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. 6 The type designation of the selected arrester will then be: PEXLIM R108-YH145 (or PEXLIM Q108-XH145) Edition 5.1, 2007-04 C-7 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. Sealing and pressure-relief function 1 Porcelain insulator 6 Sealing cover 2 Venting duct 7 Sealing ring 3 Spring 8 Indication plates 4 Desiccant bag 9 ZnO-blocks 5 Copper sheet 10 Flange cover D-1 Edition 5.1, 2007-04 The flanges are cemented to the porcelain and enclose also the sealing arrangement. 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. Installation, maintenance and monitoring Standard EXLIM arresters are intended for vertical, upright erection on a structure and require no bracing. Special EXLIM arresters for suspension, inverted mounting or other angular erection are available on request. EXLIM arresters are easy to install following the instructions packed with each arrester. Installation does not need ABB Surge Arresters — Buyer’s Guide Cutaway view of a typical EXLIM unit showing the internal arrangements designed to minimise partial discharge. Edition 5.1, 2007-04 D-2 Design Silicone-housed arrester Design features - Polymer-housed arresters, PEXLIM PEXLIM arresters, using the same ZnO blocks as the EXLIM arresters, match their electrical performance. Silicone as outer insulation material has been used for over 30 years with good results and has been chosen by ABB for arresters as well. It confers the additional benefits of low weight, improved pollution performance, increased personnel safety and flexibility in erection. Two basic designs The PEXLIM family of ABB silicone-housed arresters comes in two different designs: High strength (HS) PEXLIM tube design. Moulded PEXLIM design 1 2 3 4 5 6 7 8 E-1 Protective winding Silicone rubber insulator Base Line terminal Top yoke ZnO-blocks Fibreglass loop Bottom yoke Edition 5.1, 2007-04 1 2 3 4 5 6 7 8 Sealing cover Silicone rubber insulator Fibreglass tube Line terminal Spacers ZnO-blocks Spring Venting duct ABB Surge Arresters — Buyer’s Guide Silicone-housed arrester Design Moulded PEXLIM design 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. Cutaway view of a typical PEXLIM module showing the internal arrangements and the opencage construction designed to improve both mechanical strength and personnel safety. Edition 5.1, 2007-04 E-2 Design Silicone-housed arrester 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. E-3 Edition 5.1, 2007-04 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 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. The successful operation of the pressure-relief device is verified in short-circuit tests in accordance with IEC. Cutaway view of a typical HS PEXLIM unit showing the internal arrangements. ABB Surge Arresters — Buyer’s Guide 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 publication 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 the electrical and/or mechanical functions ABB Surge Arresters — Buyer’s Guide 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 (when supplied) match or exceed the strength of the arrester housing. Edition 5.1, 2007-04 E-4 Design Silicone-housed arrester Installation, maintenance and monitoring Standard PEXLIM arresters are intended for vertical, upright erection on a structure and require no bracing. Special PEXLIM arresters for suspension, inverted mounting or other angular erection are available on request. There are two standard ranges of the moulded design PEXLIM arresters for the following erection alternatives: • 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). All PEXLIM arresters are easy to install following the instructions packed with each arrester. Installation does not need any E-5 Edition 5.1, 2007-04 special tools or instruments. The units of multiple-unit arresters must be series-connected at site in a predetermined order as marked on the units and explained in the instructions that are packed in each case. An incorrect assembly may lead to failure and invalidates our warranty. 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. 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. More information is available in the chapter dealing with this counter. ABB Surge Arresters — Buyer’s Guide Transmission line surge arresters PEXLINK The PEXLINK concept Both large and small public/private 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. 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 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. 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. More information on internet Visit www.abb.com/arrestersonline for viewing the PEXLINK video. Edition 5.1, 2007-04 F-1 PEXLINK Transmission line surge arresters 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. late the arrester stresses at each of the 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.

F-2 Edition 5.1, 2007-04 ABB Surge Arresters — Buyer’s Guide Transmission line surge arresters 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 Surge arresters at line ends Surge arresters at line ends and two additional locations along the line The diagram shows overvoltages phaseground generated by three-phase reclosing of 550 kV, 200 km transmission line with a previous ground fault. For long EHV lines pre-insertion resistors traditionally are used to limit switching overvoltages. Surge arresters, as a robust and efficient alternative, could be located at line ends and along the line at selected points.

Edition 5.1, 2007-04 F-3 PEXLINK Transmission line surge arresters Application Line upgrading Substitute for shield wires 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 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. 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. sulation Normal in strength (BIL) No arresters at all.

Generally, the same is placed in the earth circuit of the arres- Standard line clamp Shunt Clevis link ter but depending on the configuration, it may be placed at the high-potential end of the arrester. Please refer to the figures mentioned above. 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 arrester lead to any interference with other live parts. Thus, after a failure, the line can be re-charged without attending to it immediately. The disconnection is easily visible from the ground and thus locating it is simple for the maintenance crew. Easy to install The PEXLIM arresters are built-up of optimum-length modules and hence can be easily designed for use on various voltages. They are light and hence easily transported up the towers.

Routine tests Routine tests are performed on ZnO blocks as well as on assembled arrester units and accessories. The most important type tests data is verified on all batches of ZnO blocks, thus verifying catalogue data. Tests on ZnO blocks Energy withstand test on all blocks The blocks pass three energy test cycles with cooling in-between. In each cycle, the injected energy is far in excess of the single impulse energy capability. Blocks with insufficient energy capability are automatically rejected. Classification of all blocks The blocks are classified at 1 mA (d.c.) and 10 kA (8/20 µs) and the residual voltages are printed on each block together with a batch identification. Finally all blocks are visually inspected. Accelerated life tests on samples Power losses after 1 000 hours calculated from a test with shorter duration (approx. 300 hours) at an elevated temperature of 115°C at 1.05 times Uc shall not exceed the losses at start of the test. Batches in which unapproved blocks appear are rejected. Impulse current tests on samples Blocks are subjected to high current impulses (4/10 µs) and long duration current impulses (2 500 µs) of amplitudes verifying catalogue data. Other sample tests In addition to the above, low current characteristics, protection characteristics and capacitance are checked on samples. ABB Surge Arresters — Buyer’s Guide Tests on assembled mechanical units Routine tests on units fulfil the demands of both IEC 60099-4 and ANSI/IEEE C62.11. Each arrester unit has a serial number as per IEC 60099-4 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 and HS PEXLIM 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.

Edition 5.1, 2007-04 Q-6 EXCOUNT-II Accessories 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. R-1 Edition 5.1, 2007-04 ABB Surge Arresters — Buyer’s Guide Accessories 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.

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 corresponding 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 then housed in an elegant vented aluminium casing. A suitable-angled window permits easy reading of the 6-digit cyclometer-typ counter. S-1 Edition 5.1, 2007-04 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. ABB Surge Arresters — Buyer’s Guide Accessories EXCOUNT-A Routine tests Type tests EXCOUNT-A has been subjected to severe electrical, mechanical and climate tests: Shock test, 15 g IEC 60068-2-27 Vibration test IEC 60068-2-6 Temperature test (-55°C/+70°C) IEC 60068-2-14 Humidity test IEC 60068-2-30 Salt fog test (500h, +35°C, 95%RH, 5% salt) DIN 50021 Impulse tests IEC 60099-4 Short-circuit test (full asymmetry of 2.6) IEC 60099-4 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.
