Busbar Insulation Resistance Testing
Busbar Insulation Resistance Testing
(OP)
I am re-utilising previously idle and dismantled 11 & 33kV switchgear. Will conducting Insulation Resitance (IR) test at 500V give me an indication of the likely condition of the busbar insulation, if so what value would be an acceptable IR reading? I would of thought >100 Mohm
I will of course be conducting full pressure and partial discharge testing of the switchgear when assembled.

RE: Busbar Insulation Resistance Testing
You should test the gear at a minimum of 2500Vdc for 15KV rated switch gear. I don't have the book in front of me right now but I think that the minimum insulation resistince for 15KV gear tested at 2.5KVdc is 500megohms. I will look it up tommarow an let you know.
