29、 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ELECTROMAGNETIC COMPATIBILITY (EMC) Part 4-30: Testing and measurement techniques Power quality measurement methods 1 Scope This part of IEC 61000-4 defines the methods for measurement and interpretation of results for power quality parameters in 50/60 Hz
30、a.c. power supply systems. Measurement methods are described for each relevant type of parameter in terms that will make it possible to obtain reliable, repeatable and comparable results regardless of the compliant instrument being used and regardless of its environmental conditions. This standard a
31、ddresses measurement methods for in situ measurements. Measurement of parameters covered by this standard is limited to those phenomena that can be conducted in a power system. These include the voltage and/or current parameters, as appropriate. The power quality parameters considered in this standa
32、rd are power frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells, voltage interruptions, transient voltages, supply voltage unbalance, voltage and current harmonics and interharmonics, mains signalling on the supply voltage and rapid voltage changes. Depending on the
33、purpose of the measurement, all or a subset of the phenomena on this list may be measured. This standard is a performance specification, not a design specification. The uncertainty tests in the ranges of influence quantities in this standard determine the performance requirements. This standard give
34、s measurement methods but does not set thresholds. The effects of transducers being inserted between the power system and the instrument are acknowledged but not addressed in detail in this standard. Precautions on installing monitors on live circuits are addressed. 2 Normative references The follow

A voltage channel is by definition the difference in potential between 2 conductors. Phase refers to a single conductor. On polyphase systems, a chan
