This standard addressesmeasurement methods for in situ measurements.Measurement of parameters covered by this standard is limited to voltage phenomena that canbe conducted in a power system. The power quality parameters considered in this standard arepower frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells,voltage interruptions, transient voltages, supply voltage unbalance, voltage harmonics andinterharmonics, mains signalling on the supply voltage and rapid voltage changes. Dependingon the purpose of the measurement, all or a subset of the phenomena on this list may bemeasured.NOTE 1 Information about current parameters may be found in A.3 and A.5.This standard gives measurement methods and appropriate performance requirements, butdoes not set thresholds.The effects of transducers inserted between the power system and the instrument areacknowledged but not addressed in detail in this standard. Precautions on installing monitorson live circuits are addressed.NOTE 2 Some guidance about effects of transducers may be found in IEC 61557-12.【中国标准分类号】: L06【国际标准分类号】: 33_100_01【页数】: 66P.;A4【正文语种】: 英语
