This spark length is measured from the toroid to a 7-12 inch ground
Does the ground terminal HAVE to be of 3-6" radius?
It may then be compared with the peak DC potential charts in the
Handbook of Chemistry & Physics. Use the standard impulse generator chart
for best accuracy.
This method has long been overlooked by experimenters but is possible
because the sparklength in a single shot mode is completely independent of
the waveform (Abbdulah's book on HV Engineering).
It is a bit disappointing to discover your 4 ft. long continuous spark
shrinks to only 7 inches in the pulsed mode and gives a true output of
approx 160 kV. It's hard on the ego after you have told all your friends
your coil is running at 1/2 a million volts!!
FWIW, I had this epiphany a few months back. What happens every 10mS
that makes the spark channel dissipate?
Or as Richard Hull posed, why does the streamer *go out* at all?
Why don't all streamers follow the same channel? I suppose the same
goes for non-TC sparks...
