I would have expected that the inductance would dominate the branch impedance at line frequency and its harmonics.

It's how I do it. It comes as a surprise to some people that the voltage goes up when you put a big capacitor across the supply. Don't go over the top with BIG caps and resonate the supply inductance. You would NOT like the result, and neither would the electricity supplier. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
