| Title | Electromagnetic compatibility (EMC) - Part 4-30: Testing and measurement techniques - Power quality measurement methods |
| Project Number | 21375 |
| Abstract/Scope | IEC 61000-4-30:2008 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. IEC 61000-4-30:2008 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. IEC 61000-4-30:2008 has the status of a basic EMC publication in accordance with IEC Guide 107. This second edition cancels and replaces the first edition published in 2003. This edition includes the following significant technical changes with respect to the previous edition: - Adjustments, clarifications, and corrections to class A and class B measurement methods. - A new category, class S, intended for survey instruments, has been added. - A new Annex C gives guidance on instruments. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
