Abstract [en]

Electromagnetic Compatibility in the frequency range 2 −150 kHz (supraharmonics) is an increasing concern. Recently compatibility levels have been finalised and the work on emission limits has started. Up to now no normative method to measure supraharmonics in electricity networks exists in the relevant standards of IEC 61000 series. Due to the lack of a normative method, instrument manufacturers have started to implement individual measurement methods, which differ from each other and do not provide equal results for the same signal. This paper studies commonly implemented frequency domain methods, which are either based on IEC 61000-4-7 or the informative annex of IEC 61000-4-30. The paper identifies parameters, which can influence the measurement results and studies their impact on reproducibility and comparability of the methods. Based on the results the paper provides recommendations, which shall contribute to the ongoing maintenance work on IEC 61000-4-30 regarding a normative measurement method for the frequency range 2 – 150 kHz.
