Her's where I show my ignoarance, but aren't joules a measurement of stored/generated then discharged energy? I know all our strobe power supplies and things like defibrilators and "thumper" partial discharge cable fault locators, (
http://www.hipotronics.com/ ) by example are devices expressed in joules. But my megger can apply a fairly steady voltage into a cable under test, but does so at a maximum 5 milliamp output.
If you are talking about the voltage that capactively builds up and can lay stored on a long cable run, I guess that would be applicable, but would vary with a number of factors including the length of the run and the amount of energy wou were able to dump into the cable in the first place.
