    equivalent THDv

    Sorry, I was away a few days. Loads are mainly motors driven by VSD. I'm not really concerned by the value itself, as it remains under 3%. My concern was to try to calculate the value on the 13.2kV side. But it seems clear we can't. Thanks

    equivalent THDv

    Thanks Yes, transformers are loaded (40% for 1st one, 50% for 2nd one) and supply different gears, so as you said, nothing in commom except primary voltage. Unfortunately, no meters on the 13.2kV side.... My guess is less than 1%, but I was wondering if any calculation method (even...

    equivalent THDv

    Hi, I have 2 transformers on which I could measure THDv on the LV side. 1% on 1st transformer (2.5MVA), 2.1% on the second one (2MVA). Both Transformers are supplied by the same 13.2kV switchgear Is there an easy way to calculate the equivalent THDv on the 13.2kV side? Thanks
