(29) Inter-harmonic voltage and inter-harmonic current (Uiharm, Iiharm)
Measurement method Compliant with IEC61000-4-7:2009
After harmonic analysis, harmonic voltage and harmonic current are displayed by adding as inter-
harmonic contents with the harmonic contents according to harmonic order
Measurement accuracy is defined 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)
Number of window points Rectangular, 4096 points
Displayed item From the 0.5th to 49.5th order (with a fundamental wave of 40 Hz to 70 Hz)
Select either RMS or content percentage (When using content percentage, Zero-display range
causes all orders to be given as 0% when the RMS value is 0.)
Measurement range Inter-harmonic voltage: U1 to U4, 600.00 V
Inter-harmonic current: I1 to I4, Varies with used current sensor (see input specifications).
Measurement accuracy Inter-harmonic voltage (Defined for a nominal voltage of at least 100 V.)
1% or greater 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.
