Re: We are KILLING our HV diodes Well, Maybe

Well, you have a high current discharge of the capacitance (whatever it is),
which is limited only by the inductance of the path to ground.

At my work, we do VERY high voltage work, and we always use a resistor to
ground, then do a final ground with a true ground clamp. This limits the
discharge to milliamps or amps instead of tens, hundreds or thousands of
amps, so you don't blow anything inline.

So go ahead an get a 1 meg resistor or so, but it should be a high voltage
resistor like at least 5KV rating so you don't trash it on the first use.
