The primary circuit IS NOT insulated from the secondary. The whole
system is designed around copper tubing, which has NO insulation. The
reason is to allow changing the tapping of the system, to tune the coil.
Getting too close to this circuit will cause a white hot arc (like in the
spark gap) to hit your body, causing a BIG SHOCK. I hit the primary
circuit of a small (2000v) coils, and I though I would die. Never again!
What about the secondary? I understand that the output of a

The high frequency electricity should show the skin effect, passing over
the surface. This is like being in a car when it's struck by lightning.
