The caps are in series, so each cap needs only one half the voltage rating
required for a single cap. As Terry pointed out, if one cap shorts, it will
probably destroy the other one as well. Two 1.0 ufd caps would yield an
equivalent capacitance of .50 ufd, which would only be used on a large, high
powered coil. Most of the small to moderate sized coils utilize caps in the
range of .005 ufd to .10 ufd.
Waaaaait a min.
both caps need to only be 1/2 the req voltage, but x2 capacitance??
Theoretically, you could run a 6kv 1.0 mu-f cap on each HV line and not be
under the req cap voltage rating with a 9kv 30ma nst??
How does that work, exactly...
I agree. Richard Quick Is the only coiler that I know of that built an
equidrive coil system. I believe he used two .10 ufd caps. His system
worked very well, I have video of it running. Twelve to fourteen foot arcs
if I remember correctly. He liked the set up. I have not seen evidence of
increased performance with this system over the single cap design. The
equidrive caps only need half the voltage rating but need to be twice the
capacitance. You also must remember to discharge the caps after every run
the transformer secondary windings will not provide that function as it does
with a single cap.
