BS EN 61000-4-7:2002+A1:2009 Electromagnetic compatibility (EMC) - Part 4-7:Testing and measurement techniques - General guide on harmonics and interharmonics measurements and instrumentation, for power supply systems and equipment connected thereto
This part of IEC 61000 is applicable to instrumentation intended for measuring spectral
components in the frequency range up to 9 kHz which are superimposed on the fundamental of the power supply systems at 50 Hz and 60 Hz. For practical considerations, this standard distinguishes between harmonics, interharmonics and other components above the harmonic frequency range, up to 9 kHz.
This standard defines the measurement instrumentation intended for testing individual items of equipment in accordance with emission limits given in certain standards (for example,
harmonic current limits as given in IEC 61000-3-2) as well as for the measurement of harmonic currents and voltages in actual supply systems. Instrumentation for measurements above the harmonic frequency range, up to 9 kHz is tentatively defined (see Annex B).
