Describes the methods for measurement and interpretation of results for power quality parameters in a.c. power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz.

This part of IEC61000‑4 defines the methods for measurement and interpretation of results for power quality parameters in a.c. power supply systems with a declared fundamental frequency of 50Hz or 60Hz. Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the method’s implementation. This standard addresses measurement methods for in-situ measurements. Measurement of parameters covered by this standard is limited to conducted phenomena in power systems. The power quality parameters considered in this standard are power frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells, voltage interruptions, transient voltages, supply voltage unbalance, voltage harmonics and interharmonics, mains signalling on the supply voltage, rapid voltage changes, and current measurements. Emissions in the 2kHz to 150kHz range are considered in AnnexC (informative), and over- and underdeviations are considered in AnnexD (informative). Depending on the purpose of the measurement, all or a subset of the phenomena on this list may be measured. NOTE1 Test methods for verifying compliance with this standard can be found in IEC62586‑2 . NOTE2 The effects of transducers inserted between the power system and the instrument are acknowledged but not addressed in detail in this standard. Guidance about effects of transducers can be found IECTR61869‑103 .
