Not sure I want to attempt to measure capacitance as I wind up the voltage to several kV
I suppose I could find some bigger caps rated at several kV and put them in series. Then hope my DMM or Peak capacitance meter doesn't get the wrong sort of ouch as things charge and discharge. Zeners in inverse series perhaps?
Anyway, if the 1n and 10n caps can withtand 5kV I'm sure they'll be fine for any normal radio or TV decoupling jobs. But I'll keep them away from LOP pulse roles.
One day I'll acquire or build a higher voltage PSU. An old Brandenburg 25kV job would be nice. Otherwise I've got some old diode split LOP transformers from computer monitors which could be turned into simple variable EHT supplies. I'd build in a metering resistor which would double as a safety discharge. Maybe one day.
This sort of thing, but made easier with a diode split LOPT: http://www.iaeng.org/publication/WCECS20...06-209.pdf
