Hi John,
 
12 kV is the RMS voltage of your transformer. The peak voltage is 16.97 kV  ( 
RMS X sqrt(2) )

Subject: capacitor charging & SG  question

Hello. It's been many months since I was into doing the math  and
calculations for my tesla coil. I am getting back into it  now.

If I have make a bank of 11 50KVDC (~20KVAC) strontium  titinate
ciramic caps giving a total parellel capacitence of 0.01uF   (which is
about perfect for an LTR capacitance for my 12kv/30mA  NST)

Will the max storage voltage of this bank (and what I should set  for a
static air gap) be 12kv?

It's like if I had a 9 volt battery I  wouldn't be able to change up a
photo flash cap more than 9 volts. So with  this assumption should I
set my static spark gap at just under the  breakdown of 12kv?


Thanks,
John.

BTW, I know these caps  will slowly loose capacitance over time....its
what I'm working with  ATM.
