line. but line voltage comes to 132 kv, it operate or
not???
Answer Posted / 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.
