Hello Coilers,

I know, how to calculate the "line-frequency-resonant" capacitance 
of tank caps for use with NSTs and asynchron gaps like statics 
and ARSGs. From the list I have learnt, that with synchron gaps 
like SRSGs and TSGs, it's much better/safer to use LTRs, having 
got about 1.5 times the calculated capacitance.

As I want to test and compare both types of spark gaps in my next 
system, I would like to ask you for your assistance:

NSTs are hard to come by in this part of the world. Therefore I'll use 
either a pair of LV-ballasted MOTs (for 4 kVrms) or two MOTs 
driving level shifters (for 12 kV pulsed dc). The first solution will use 
inductive ballast and the second one has got a kind of built-in 
capacitice ballast. IMO(!) these ballasts need to be included in the 
calculations.

Q: How should I calculate the capacity of LTR-tank caps for both 
types of power supplies?

Safe coiling to you!
