I am talking about the grounded platform the switch operator stands on while opening and closing the switches. We require them on our 110KV bus switches but not our 22KV bus switches. I was wondering if there is some standard that indicate when they are required.
Currently we require switching platforms for operators to stand on while switching all our 110KV air switches. There is no requirement to have them for our 22KV air switches. Is there a standard voltage requirement to have them? Thanks for all responses.
