Re: [TCML] Bipolar Capacitance Orientation

[Gary Lau <glau1024@xxxxxxxxx>]

You can't use an LC meter to measure secondary capacitance, regardless of
orientation.  The secondary capacitance is only a few pF (probably beyond
the resolution of most LC meters), and any attempt to hook up test leads
would alter and overwhelm the coil's capacitance.

The only way to measure it is indirectly, by allowing Csec to resonate with
Lsec and measuring the frequency.  You'll need to be careful about how you
excite the resonance.  Unlike a "normal" secondary, you can't just
bottom-feed it; it must be in the final horizontal position with all planned
electrodes.  Probably need to use an un-tuned primary to couple the
excitation signal.  Not a trivial exercise.
