The problem with using power frequency AC test sets to perform AC Withstand testing and Partial Discharge and Tan Delta/Power Factor testing is the high kVA capacity required if your test winding is high in capacitance. VLF can be used to help minimize this power. Question: is there a source somewhere that shows the typical uF ratings of stator windings, and others, of typical size motor and generator coils? Maybe a few for windings with a kVac input voltage of 2.4, 4.16, 13.2, 25, etc, I know there are a million possibilities but if perhaps any model listings of vendors that might show the capacitance along with all the other specs. Or, how about just for hydro generators. thank you.
