I noticed that when testing hipot in DC I always get leakage current, but not during AC hipot testing. Do you have any ideas about this? My hipot tester is Quadtech Sentry 500VA. I’m testing a dielectric made of PEEK and alumina.

    \$\begingroup\$ Strange. I have had the opposite happen to me. Can you share a schematic or block diagram? \$\endgroup\$

  • \$\begingroup\$ Oh, PEEK, my favorite plastic. Interesting. Any dielectric properties would not change much between DC and 50 Hz. Do you have no active parts at all? \$\endgroup\$
