RE: [TCML] HV Panel Meters
You can use a standard AC analog meter, but here's a couple things to think about.
1) You'd have to take special precautions to ensure that all parts of the meter are thoroughly insulated from a panel and contact with people. It's probably not advisable to mount it permanently on a panel.
2) AC meters are calibrated to read RMS current, and assume that the input waveform is a sine wave. The current drawn from an NST into an operating Tesla coil does not remotely resemble a sine wave and I can't offer any sort of conversion factor. So you might benefit form seeing a relative indication, but the actual current value would be unknown. To get a useful RMS current reading, you would need a true RMS meter, which typically being digital, is subject to haywire behavior anywhere near a Tesla coil.
