MMC dissipation factor measurement
Original poster: "Terry Fritz" <twftesla-at-qwest-dot-net>
The question comes to me tonight....
I have a TEK 3012 scope. I have a TEK 5100 voltage probe, lots of Pearson
current monitor CTs... I have a lot of sine wave generators with low
impedance... Like 350kHZ at 5 amps...
So, would I have any chance "in the hot place" of measuring the dissipation
factor of a poly MMC cap? Like <0.001 dissipation factor...
I guess I would have to detect the difference between 90 degrees and
89.87856 degrees to find the dissipation factor...
Sounds doable but maybe someone out there has "been there, done that..." I
was just asked the question and "I" have not thought much on it cause I am
sleepy :o) Might need a step down transformer to get a really low source Z....
