Buck,
My megger is hand held old style with a crank. All it does is measure insulation or dielectrics resistance. Never measured the voltage it outputed but Vishay caps for mags are rated at 850 volts. I’ll try a used cap for electronics first & let you know. I like expermenting, Boom!!!
I would bet the socket you speak of was 480 volts, 3 phase too. All a megger does when cranked is generate electrical current. Your guys had a motor to spin the genny too. You may be speaking of hi-pot test. It’s a megger on steroids. We hi-potentialed tested service sections before powering. It too checks insulation resistance only to the third degree.
P.S. anything less than 2 meg ohms is a failure.
