Jim,

Was this "several meter" spark self started at 60 kV (I would highly
doubt it) or was it drawn out this far after bringing the elec-
trodes much closer together to start the arc and then drawn  out
to several meters (much more likely)? Likewise, the 300 kV of the
VDG is only able to jump as far as the ROC of the discharge electrode
allows for the spark to self start and with the very limited avai-
lable current, the "drawn out" arc length is basically limited to
the "self-start" spark length.
