RE: Tesla coil output voltage

JT, please be cautious (you stated: I have access to a whole high school
electronics lab. There's literally more equipment in it than any member
in this forum has) as I work for the leading semi conductor company in
the world and sitting in front of a 18 million dollar tester with a 1/2
million dollar scope looking at a high speed PCI express bus on our new
1G network processor (Azusa) with a 500k dollar probe. If you are ever
in Arizona I will give you a tour of our lab! Position the issue you
want answered but do not compare $$$$$, as someone might get a laugh or
even worse take it the wrong way.

Cheers,
christopher

1kV  (note well.. the prefix kilo is abbreviated with lower case k)
that's better than 1% accuracy, which is quite a challenge.

That's something I kind of doubt.

You need to build calibrated E-field probes (search the archives for
details).  You set up the probe with your measurement equipment and
put a known voltage on the tesla coil (using a calibrated signal
generator).  That gets you the calibration factor for your
measurement system (i.e. if I measure 20 millivolts on my probe, and
there's 1000V on the toroid, then then every volt on the probe is
50kV on the toroid).

You'll need a way to put known voltages on the toroid.
