Hi
We have several times been asked to test Inrush Current and have this function on our Harmonic tester, but it is not defined how it measure and we get very different measurements each time we switch ON the same EUT. I can't find an IEC definition on the measurement other than "peak current". I asume that it is most correctly to measure the current by switching ON at the top of the sine (90 deg), but what about duration? A peak current with a duration of 0.1 ms is not as interresting as the same current for 1 ms. And what if there are several current peaks after each other such as ringing wave form?
