Inter-harmonic voltage and inter-harmonic current (Uiharm, Iiharm)
Measurement method Uses IEC61000-4-7:2002.
Anti-aliasing low-pass filter causes attenuation of frequencies other than measurement target of at
least 50 dB.
After harmonic analysis, harmonic voltage and current are summed and displayed as inter-har-
monic contents with the harmonic contents according to harmonic order
Measurement accuracy is specified for input that is 10% to 200% of IEC61000-2-4 Class 3.
Analysis window width 10 cycles (50 Hz) or 12 cycles (60 Hz)
No. of window points Rectangular, 4,096 points
Displayed item 0.5 to 49.5 orders (of 42.5- to 70-Hz fundamental waveform)
Select either RMS or content percentage (When using content percentage, zero suppression
causes all orders to be given as 0% when the RMS value is 0.)
Measurement range, resolution Inter-harmonic voltage: U1 to U4, 600.00 V
Inter-harmonic current: I1 to I4, Varies with current range (see input specifications).
Measurement accuracy Inter-harmonic voltage (Specified with a nominal voltage of at least 100 V.)
At least 1% of harmonic input nominal voltage:: 5.00% rdg.
<1% of harmonic input nominal voltage: 0.05% of nominal voltage
Inter-harmonic current: Unspecified
Event threshold N/A
Constraints Not displayed for 400 Hz measurement.
