Grounding 4,15 or 34.5 kV metal clad switchgear for field maintenance
Grounding 4,15 or 34.5 kV metal clad switchgear for field maintenance
(OP)
I am working on specifying 34.5 kV indoor metal clad switchgear. I was wondering if any one knows before field personal work on the breaker what is grounded. I know that some metal clad switchgear have grounded metal shutters that seperate the stabs of the circuit breaker from the bus and feeder duct. But what other grounding is done.
