Re: Spice simulation pictures


No.  My secondary is too big to haul to the lab for measurement purposes.
I am planning on making a small 4" coil for this very purpose.  It will be a
while as my present work on the 1/2 MV crowbar switch will take a lot
of time away from coiling.  When I can find a time window I would like to
do these measurements with a signal generator VS live running coil
to ascertain the effect if any of the corona (electron) sheath about the
coil on the live proximity effect.
