7.3 Test set-up and test procedure
Harmonics of the fundamental current were measured up to 2 kHz using a digital power analyzer.
The test voltage was supplied from an AC source which meets the requirements according to the
standard.
The test voltage was supplied from an AC source which meets the requirements according to the
standard.
The measurement of harmonic currents was performed in the following way:
-
For each harmonic order, measurement of the 1,5s smoothed r.m.s. harmonic current in
each DFT time window were performed.
each DFT time window were performed.
-
Calculation of the arithmetic average of the measured values from the DFT time windows
over the entire observation period was performed.
over the entire observation period was performed.
7.4 Measurement uncertainty
The measurement uncertainty is:
± 8,4 %.
Measurement uncertainty is calculated in accordance with EA-4/02:1997.
The measurement uncertainty is given with a confidence of 95%.
The uncertainty of the measured values is within the tolerance specified by the standard.
