11kW Switchgear Testing
11kW Switchgear Testing
(OP)
Hi guys,
Do either of you have a good spec for testing 11kV indoor switchgear?
I am extending an 6.6kV SB for our customer by adding a couple of CBs.
I was going to recommend the following tests but would welcome any comments and suggestions:
1. Ducter new bus connections
2. 5kV Megger
3. Primary and secondary injection tests
Was also considering Hi-pot but I'm not sure if that is really used anymore for MV switchgear?

THere are a few optional tests in the specs so you may want to clarify if you want those done or not.
RE: 11kW Switchgear Testing
for high-voltage switchgear and controlgear standards section lists the routine tests which included dielctric (high voltage) testing.
Primary and secondary current injection will verify the CT/protection relay scheme
RE: 11kW Switchgear Testing
On medium voltage switchgear, ct testing is usually performed with the voltage method.
