"I just use a 100K resistor in series with an isolated HT power supply and measure across the 100K resistor with a DVM and calculate the leakage currant. "
Is this good enough for say SM?
Me, I have a Levell Insulation Tester TM14 picked up at an NVCF. Great tester, battery powered with an inverter for voltages from 10 to 1000V and indicates Gig Ohms.
