CAN/CSA-C61000-4-30-10 (R2014)
CSA Preface
This is the second edition of CAN/CSA-C61000-4-30, Electromagnetic compatibility (EMC) — Part 4-30:
Testing and measurement techniques — Power quality measurement methods, which is an adoption, with
Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard
61000-4-30 (second edition, 2008-10). It supersedes the previous edition, published in 2004 as
CAN/CSA-CEI/IEC 61000-4-30 (adopted CEI/IEC 61000-4-30:2003).
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 a.c. power supply systems.
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 voltage phenomena that can
be conducted in a power system. 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 and rapid voltage changes. Depending
on the purpose of the measurement, all or a subset of the phenomena on this list may be
measured.
NOTE 1 Information about current parameters may be found in A.3 and A.5.
This standard gives measurement methods and appropriate performance requirements, but
does not set thresholds.
The effects of transducers 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.
NOTE 2 Some guidance about effects of transducers may be found in IEC 61557-12.
