Dear Folks,
what are the recommended commissioning tests on replacement of medium voltage circuit breakers?!
I made a list that included CT ratio and polarity tests, hipot test for the bottles, resistance tests for the contacts, megger test for the insulation, finally, functionality test for breaker control/power circuits.
did I miss anything? do you know of a detailed guide or procedures to perform the functionality test, how to do and what to expect in detailed, technical manner.
I appreciate your help and input.
best regards,
