Gas insulated switchgear
Gas insulated switchgear
(OP)
In a GIS switchgear ( 34.5 KV) with three position switch of Isolator , circuit breaker & earth switch,if the cable is removed from the outgoing cable chamber & the breaker is closed , opened many times. After that if the earthing is done. The procedure for earthing is closing the earthing & closing the breaker ( earhing in GIS is done through the breaker). Will there be any static chrage inside the cable & is that static charge dangerous.
thanks in advance

I mean to say that,will there be any static charge in the cable chamber ( not the cable)
The cable is disconnected from both the ends

Attention because the bus is live and safety distances have to be respected. Only visual inspection is allowed.
RE: Gas insulated switchgear
THis is one of the breakers in the bus, if the breaker is open there is no voltage at the cable chamber.The cable was removed for the interconnection test.
After the testing the GIS switchgear was earhted as per normal procedure.
The question is that after Earthing will there be any static charge to injure someone.
