For pure AC inductance, I am going to use 60cps because it is easy. A resistor in series, to determine AC current( from teh department of redundancy department ). {V-inductor/V-resistor} times {R/2Pi60}=inductance in Hy.

An adjustable current regulator with DC voltage supply greater than V-ac peak-to-peak ought to allow me to determine its DC tolerance. Say a 40 vac signal and a 200VDC supply feeding the current regualtor. Might have heat issues with the CCS, but that's OK, I can deal with that.

Any suggestions at improving this method?

The connection leads from every component are separated by a distance, so there are two conductors separated by space. That forms a very small capacitor. When a voltage differential is applied across the device, an electrostatic field sets up in the dielectric of the air.

The wire leads into the device also act as inductors. When current flows through the device, a magnetic field is setup around the conductors. That gives the device inductive reactance.

So no matter what the device is, it has values of capacitance, inductance and resistance. There is a frequency where the device acts as a resonator, without any other components attached. This is the self-resonant frequency of the device. It's usually a very high frequency.
