High voltage AC withstand testing breakers and SG. What is phase to ground capacitance?
High voltage AC withstand testing breakers and SG. What is phase to ground capacitance?
(OP)
Age old question: sizing the AC hipot. What is the capacitance from ph. to grd. and ph. to ph. of typical breakers from 5kV - 150 kVac? I don't find this information easily from the CB vendors. I know most of them but not all and not the newer rated apparatus and the HV models. Does anyone have a chart of the typical capacitances to calculate the current required to perform the withstand test. Right now I need it for a 66 kV SF6 breaker. To test one breaker is easy but when testing multiple units, it's helpful to know.
Thank you.
Thank you.
