Customers sometimes want both the highest peak current and an rms over a
defined number of line cycles. If the request is exclusively standards based,
John's suggestion works well. You'll need to perform five to ten tests randomly
closing on the supply cycle and pick the highest values.

Look at Annex B of IEC/EN 61000-3-3. I did a lot of work on this for that Annex
and you will often get different results each time, because of differences in
how the current is interrupted at the previous switch-off. You do not select a

I think it also depends on what your EUT is.

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
