1 Scope
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…
