(25) High-order harmonic voltage component and high-order harmonic current component (UharmH, IharmH)
Measurement method The waveform obtained by eliminating the fundamental component is calculated using the true
RMS method during 10 cycles (50 Hz), 12 cycles (60 Hz), or 80 cycles (400 Hz) (approx. 200 ms)
of the fundamental wave.
