[TCML] pole pig minus case

[David Rieben]

Hi Jorge,

I have personally removed a pole pig's "guts" from the tank
and ran it dry, although I did NOT run a Tesla coil with it in
this fashion. I was however able to run up to 280 volts through
the 240 volt side while the HV side was completely open cir-
cuit with little audibly detectable corona "hiss" sound. Of course
I was also able to draw arcs from it to run a Jacob's ladder as
well, so you could probably get by with running your pig "dry"
to fire a coil. Butyl encased potentail transformers (PTs) seem
to handle running dry fine but these transformers are desinged
to run "dry", too. OTOH, pole pigs are really only designed
to run in oil, so I still personally would preder to run a pole pig
the way that it was designed to run - in oil, especially when firing
a Tesla coil, due the overvoltage transient kickbacks from the
primary tank circuit that often find their way back to the trans-
former.

David
