“…The assessment of current harmonics generated by equipment connected to the power system is of paramount importance in the field of electromagnetic compatibility (EMC). Efficient assessment serves as a preventive measure against the propagation of electromagnetic disturbances and safeguards the overall power quality [ 1 , 2 , 3 , 4 , 5 , 6 ]. The standards IEC 61000-3-2 and IEC 61000-3-12 define the limits for the harmonic current generated by the low voltage equipment connected to the power system [ 7 , 8 ].…”

The aim of this paper is to determine the conversion accuracy of the Danisense DC200IF (Danisense A/S, Taastrup, Denmark) wideband current transducer for its possible application to test electromagnetic compatibility requirements of the standards IEC 61000-3-2 and IEC 61000-3-12 with the digital power meter Yokogawa WT5000 (Yokogawa Electric Corporation, Tokyo, Japan). To obtain this goal for distorted current of main frequency equal to 50 Hz and in the frequencies range of higher harmonics from 100 Hz to 2500 Hz its amplitude error and phase shift are evaluated. Moreover, the measurable level of higher harmonics with the rated accuracy of the used precision power analyzer is also investigated. Finally, the measuring system is applied to determine the RMS values of current harmonics produced by the audio power amplifier in order to assess its compliance with the standard IEC 61000-3-12.
