capacitor bank switching
capacitor bank switching
(OP)
The formulas that are derived in ANSI/IEEE c37.012
"IEEE application guide for capacitance current switching for AC high-voltage circuit breakers rated on a symmetrical current basis" are for what situation?I mean could they be used for both earthed and non-earthed neutral conditions?
thanx.

RE: capacitor bank switching
If the former, it is a 'restrike-free' question.
If the latter, people use pre-insertion inductance and other techniques to mitigate the switching overvoltages.
