Re: For maximum spark length/maximum reliability is larger than resonant cap best?
to David
A 1" poly border is not adequate for a 15 kV xmfr to resonate with. It will
require a min. of 2 inch border and then the max voltage per section should
not exceed 9 kV. In RF capacitors dielectric tracking is a serious concern
and must be addressed with wide margins if you want it to be reliable.
