Re: Spark Gap Formula Help!

A single gap works fine, especially if you have a small fan (i.e. a 3" fan
from a computer supply, for instance) blowing on it. The reason there isn't
a formula or something for the gaps is that spark gaps are "empirical",
which is just a nice way to say, try different things until it works. For
your 12 kV (RMS) transformer, a starting point would be setting the total
gap (sum of all intermediate gaps) or the single gap to about 4 mm, or 1/6
Start simple with a simple gap, then try replacing it with a fancier one and
see if it works better.
