in 132 kv substation ligtning arrestor(120 kv) connected to line. but line voltage comes to 132 kv..

Answer / vettum perumal

Ligtning Arrestors are connected across one phase and
earth. Hence,the insulation of the arrestor shall be
suitable for only phase voltage. that is, 132kv/root3 =
76KV.Hence, these 120 KV LA will operate very well.

Answer / s.rajasekar

the lightinig arrestor connected with line in parrallel
then the volage range will divided by root 3.so the
insulation level of the arrester is suitadable for 132kv
system

Answer / avradeep das

In any conductor of 132 KV transmission line rated voltage
with respect to ground(remember LA is connected between one
conductor/phase and earth)is 76(approx) KV so 120 KV is
adequate
