yes, and the power factor as well. For the most part the test well over like 50%, if it was under I would reject it outright. I like to compare them to new caps, they generally test higher value, about the same in power factor, and up to about 2 to 4 times the leakage (but its still very low). I used to have a chart that was used for acceptable leakage.
It would not be uncommon for me to take more that 24hrs for one section. Is this really needed, maybe not but it cant hurt to try and besides like I said before it appeals to my interest in experimenting.
What I would really like would be a test setup that I could program to step up the voltage based on current, say have it ramp up to try and maintain a set constant leakage current (selectable), then graph that voltage over time and set the max voltage to end the test. The resulting curves would be fun to examine.
you could do it with a constantly variable DC power supply and a current meter (analog would be easy to watch) but I dont really want to stand by the PS and work that for however long it may take.
