Type POLIM-HM Surge ArrestersMaximum System Voltage 2.52 to 245 kV

2 POLIM-HM Metal Oxide Gapless Surge Arresters

POLIM-HM Surge Arresters are used for the protection of switchgear, transformers and other equipment in high voltage systems against atmospheric and switching overvoltages. For use when requirements of lightning intensity, energy capability and pollution are moderate.

Superior design where low weight, reduced clearances, flexible mounting, and shatter-proof housing is required.

ApplicationThe POLIM-HM Surge Arrester has been verified to meet Station Class requirements of IEEE C62.11 (IEEE Standard for Metal-Oxide Surge Arresters for AC Power Circuits) and Line Discharge Class 4 requirements of IEC 60099-4 (IEC Standard for Metal-Oxide Surge Arresters without gaps for AC Systems). The POLIM-HM Surge Arrester is designed to meet the following performance data:

Benefits

Direct-molded constructionABB’s POLIM-HM Surge Arrester consists of high performance metal oxide disks molded in a shatter-proof polymer housing. The POLIM-HM Surge Arrester now has a new construction to enhance overall lifetime performance. The metal oxide disks are enclosed in a support assembly consisting of reinforced epoxy/fiberglass loops connecting the upper and lower aluminum end pieces. The silicone polymer material is then molded directly to the metal oxide loop assembly eliminating any air pockets which could cause moisture ingress over time.

Each arrester is furnished with a mounting base for an 8.75 in / 222 mm to 10.0 in / 254 mm diameter bolt circle along with 4-hole NEMA pad, and line and ground terminals for electrical connections.

100% silicone based housingThe silicone rubber housing features high tracking and arc resistance, excellent hydrophobic properties, and resistance to weathering, UV radiation and pollution.

Standard (Stainless steel)

Reduced electrical clearancePolymer construction has resulted in much smaller housing dimensions in comparison with porcelain units of the same voltage rating. This size reduction enables efficient use of space for switchgear enclosures, mobile substations and other applications where space restrictions are present.

LightweightThe POLIM-HM Surge Arrester is less than 50 percent the weight of its porcelain counterpart, which results in easier handling and installation.

Damage resistantPolymer construction reduces possible shipping and handling damage, as well as, damage due to vandalism.

SafetyShatter-resistant construction provides greater protection for personnel, as well as nearby equipment.

The phase-to-ground clearance in substations is usually based on the selected standard rated lightning and switching impulse withstand voltages. International standards, e.g. IEC 60071-2, recommend minimum clearances.

In general, the clearance between a grounded object and a surge arrester should be the same as the phase-to-ground clearance selected for other high voltage equipment in a substation. If it is not possible to use the normal phase-to-ground clearance in special applications of POLIM-HM Surge Arresters, a smaller clearance may be chosen, considering the protective characteristics of the arrester. At system voltages 24 kV and below, the margin between the rated withstand voltage of the substation and the protective level of the surge arrester is large. Furthermore, distance effects by fast transients do not exist in the immediate vicinity of the surge arrester.

Thus, the recommended minimum phase-to-ground clearance for POLIM-HM Surge Arresters, with regard to lightning and switching overvoltages are presented in Figure 1. These clearances are based on IEC 60071-2, Table VI, and on the protective characteristics of the surge arrester. They include safety margins and altitude correction.

Phase-to-ground clearance

The Adjusted Protective Level to be used in Figure 1, is defined as:- For lightning impulse: Lpl x 1.15 x eH/8150

- For switching impulse: Spl x 1.10 x eH/8150

H is the altitude in meters above sea level.

Lpl and Spl are the lightning and switching impulse protective levels for the selected POLIM-HM Surge Arresters at the respective coordinating currents.

The minimum clearance is determined either by lightning or switching impulse withstand, whichever renders a larger value.

(cm)

The phase-to-phase clearance for high voltage equipment in a substation is normally based on the selected standard rated lightning and switching impulse phase-to-phase withstand voltages. International standards, e.g. IEC 60071-3 recommend minimum phase-to-phase clearances. Note that the normal election of surge arrester protective levels does not directly protect the phase-to-phase insulation.

In general, the clearance between surge arresters in adjacent phases should be the same as the phase-to-phase clearance selected for other high voltage equipment in the substation. If it is not possible to use the normal phase-to-phase clearance in a special application of POLIM-HM Surge Arresters, the minimum clearance with regard to lightning overvoltages can be derived from Figure 2.

The clearances shown in Figure 2 are based on the assumption that one phase is subjected to a lightning overvoltage, while the voltage on the adjacent phase is at the peak of the maximum power frequency operating voltage (opposite polarity). Obviously, these clearances will also cover the case of lightning overvoltages of the same polarity appearing simultaneously on two or three phases.

Phase-to-phase clearance

The Adjusted Protective Level shown in Figure 2 is based on the lightning protective characteristics of the selected POLIM-HM Surge Arresters. It includes safety margin and altitude correction factors and is defined as:Lpl x 1.15 x eH/8150 + Vm x √2 / √3

- Vm is the highest voltage for equipment according to IEC 60071-1, which is usually equal to the highest system voltage.- Lpl is the lightning impulse protective level for the selected POLIM-HM Surge Arrester.

The minimum phase-to-phase clearance for arresters with respect to switching overvoltages should always be based on the selected standard rated switching impulse phase-to-phase withstand voltage for the substation. Consequently, the clearances specified in IEC 60071-3, Table VI, are valid for most applications of arresters. If a special application requires a minimized phase spacing, the favorable electrode configuration established by the grading rings on POLIM-HM Surge Arresters may permit a further reduction of the phase-to-phase clearance.
