Hi Phillip,
I don't think that the "Arczilla" toys that Cameron and I
build are in the same catergory as the huge UHV trans-
formers to which Jim Lux is referring. We simply take
the standard output of a 14.4 kV pole transformer and
run its output through a capacitor of appropriate size to
induce resonant voltage rize after the arc is started. Jim
is referring to a huge transformer assembly who's out-
put voltage is in the megavolts, probably something si-
milar to this: http://www.ece.msstate.edu/hvl/testing.html
Thanks for the complement, though. ;^)
