Hi-Pot Leakage Tester Posted by Geir on January 11, 2012 Posted in: Electronics, Projects. Tagged: Hi-Pot, homebrew, Kv, projects, Tester. 4 comments Here is a Hi-Pot tester I have just finished. Hi-pot tester is good for 11Kv at the terminals and the leakage current is 3uA. I’m pretty happy with the result. Testing a Burle 8792 transmitting tube. Leakage is 3uA @ 7Kv Inside view from the top Schematics
