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.
本文的目的是确定丹麦Danisense A/S公司位于Taastrup的Danisense DC200IF宽带电流传感器的转换精度,以便其可能应用于使用横河WT5000数字功率计(日本横河电机公司,东京)测试符合IEC 61000-3-2和IEC 61000-3-12标准的电磁兼容性要求。为实现这一目标,针对主频等于50 Hz且频率范围在100 Hz至2500 Hz的高次谐波的畸变电流,评估其幅度误差和相位偏移。此外,还研究了所用精密功率分析仪额定精度下可测量的高次谐波水平。最后,应用该测量系统确定音频功率放大器产生的电流谐波的均方根值,以评估其是否符合IEC 61000-3-12标准。
