Current harmonics measurement is too big, is it common?
Current harmonics measurement is too big, is it common?
(OP)
Recently I measured current harmonics component in mine industry. But the results are not as I expected. The max current supposed to be 380 A, but when I measured my Power Quality Analyzer displays 1026 A which is at the fundamental frequency, while the total current harmonic(all frequency) is about 1200 A rms. Notice that, I measured it in one phase.

The voltage THD shall be less than 10 percent in industrial plants with an occasional 15% allowed for short periods. The voltage THD is what one usually cares about. What is it in your case?

Half full - Half empty? I don't mind. It's what in it that counts.

It's only the THDV that has any effect on your infrastructure.
