RE: breakout voltage

Ok now I am a bit confused.
When I gave the formula I had, I was informed that it was for dc
calculation and it would not work because a tc was ac and there were
other factors involved as well.

Now the method suggested to measure the max dc voltage on the toroid.
Calculated or measured it is still a dc rating and since I tc is not dc
it will be a false measure of the real max potential.

How would one measure the max potential for the conditions a tc would be
in?

It's best to actually measure the potential.

Rectify the HV to DC, and then use a 20 Meg HV resistor in series with
the
output to the cap.  This will fire a single pulse at peak DC kV on the
cap.
You can measure the discharge between the toroid and a suitable ground
electrode.  This will provide the peak potential of the system.

You can correlate this with a simple inductance ratio calculation ---
they
should be in close agreement.  Most multimeters allow inductance
measurement
of both pri and sec coils.
