Best way to reduce it is eliminate most of it with a SISG solid state
spark gap. Less heat so the normal spark gap electrodes do not get
red hot and fail to quench. Efficiency increases substantially,
usually 50% longer sparks per kVA of input power than classic air
type gaps. Typical with air gap is around 1 ft per 1 kVA while with
solid state SISG design approx 450 Watts per ft of spark for coils
with total spark outputs under 4-5 feet.
With nsts a good parallel tube gap with forced air fan works
good. Above 4 kVA just go to a nice rotary.
It varies a lot from coil to coil depending on the design. One
tip: Using a larger dia sec coil soaks up a lot more energy than a
small 2-3 inch dia sec, so less problems as the coil dia.
increases. I have some data on this but it's all back in files in WI
and I don't have access to it. Mom would never find it!!!
