Annexure-A
Surge arrester Specification (336 kV, Station Class, Gapless, Discharge Class-4)
1: The surge arrestors shall conform in general to IEC-60099-4 except to the extent
modified in the specification.
2: Arrestors shall be hermetically sealed units, self-supporting construction, suitable for
mounting on lattice/tubular type support structures.
3: The Surge Arresters (SAs) shall be capable of discharging over-voltages occurring due
to switching of unloaded transformers, reactors and long lines.
4: The reference current of SAs shall be high enough to eliminate the influence of grading
and stray capacitance on the measured reference voltage.
5: The SAs shall be capable of withstanding meteorological and short circuit forces under
site conditions.
6: Each Surge Arrester (SA) shall be hermetically sealed single-phase unit.
7: The nonlinear blocks shall be sintered metal oxide material. The SA construction shall
be robust with excellent mechanical and electrical properties.
8: SAs shall have pressure relief devices suitable for preventing violent failure of
insulator housing and providing path for flow of rated fault currents in the event of
arrester failure.
9: Outer insulator of Surge arrestor shall be of Silicon Polymer type. The SA shall not fail
due to polymer contamination.
10: Seals shall be effectively maintained even when SA discharges rated lightning
current.
11: Polymer housing shall be so coordinated that external flashover will not occur due to
application of any impulse or switching surge voltage up to maximum design value for
SA. The cantilever strength of the insulator shall be minimum 500kg for Surge
arrestor used for 400kV.
12: The end fittings shall be made of corrosion proof material and preferably be
nonmagnetic.
13: The SAs shall be capable of withstanding meteorological and short circuit forces
under site conditions.
14: The sealing arrangement of the Surge Arrester stacks shall be done incorporating
grooved flanges with O-rings/elliptical cross section gasket of Neoprene or Butyl rubber.
15: Self-contained discharge counters, suitably enclosed for outdoor use (IP:55 degree of
protection) and requiring no auxiliary or battery supply shall be fitted with each SA along
with necessary connections to SA and earth. Suitable leakage current meters shall also
be supplied in the same enclosure. The reading of milliammeter and counter shall be
visible through an inspection glass panel to a man standing on ground. A pressure relief
vent/suitable provision shall be made to prevent pressure build up.
