Stacked Acrylic ESL Insulator

[Brian Beck]

Few,

Yes, in fact, there are two time constants. At low frequencies, there is a resistive voltage divider reducing the stator voltage to what appeears across the air gap. At high frequencies, there is a capacative divider, which yields another divider ratio across the gap. In between, there will a pole and a zero with a 6 dB per octave slope (asymptote) between them. If the resistance of the stator coating is many orders of magitude lower than the air gap and the capacitive reactance of the insulator it will "short out" the a parallel cap, and put all the staor voltage across the air gap, it will push the time constants and slope way higher in frequency.

I was working on a more detailed explanation for Bazukas, but didn't havr time to finish it.

Calvin,

Postings passing in the the night like ships! Yes, I think we do agree after all (see prior post).
