Gigantic resistors

February 2, 2010

I ordered some 1000 Megohm resistors today. They’ll be the basis for some new HV measuring tools. I’m finding that I could really use a high voltage voltmeter and oscilloscope lately. Using a gigohm resistor (just like we use for the quarter shrinker) I can make a voltage divider, which will let me use my regular bench tools for testing. It looks like these will be good through 40kV, which will let me measure the performance of the pole pig! The ultimate plan is to make a voltmeter with a nixie tube display.

Why does all of the best HV stuff come from Russia anyway?
