so you need 30kV diodes, minimum. 40 or 50kV would be even nicer.
Tim, I lost you a little bit here, sorry. Are you saying that I need
single 30kV diodes and that putting 1 kV diodes in series is
unsuitable? Or are you saying that twenty 1,000 V diodes is not
enough?
30-50kV PIV "diode", collectively. You can make that "diode" out of as many
1N4001 diode*s* as you need.

Thanks, now I understand a little better. I will soon make a stack of,
say, 30 1N4007 diodes. That would let me test the capacitors with 13
kV.

Did something like that about 40 years ago. In our case we had to
bridge each diode with a small capacitor and large resistance resistor
because when seeing the reverse voltage, they did not all turn off fast
enough.
