Hi Everyone
I just measured cable factory for their power quality. The main transformer capacity 1600KVA and the load only 750KVA.
But i wonder why the voltage waveform is sinus shape but it was distorted/notched all around the waveform?
i check THDv = 4.9, THDi = 19% PF = 0.84
I went down to the sub panel (annealing machine and pump), the same result with the voltage waveform...THDv < 5% but the waveform is distorted.
1. Anyone can help to explain this issue?
2. I found the zero order, 2, 3, 4 order harmonics on the sub panel. is it because the distorted voltage?
Thank you everyone
