IEC 61000-4-30:2015

Electromagnetic compatibility (EMC) - Part 4-30: Testing and measurement techniques - Power quality measurement methods

IEC 61000-4-30:201 5 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 50 Hz or 60 Hz. 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 2 kHz to 150 kHz range are considered in Annex C (informative), and over- and underdeviations are considered in Annex D (informative). Depending on the purpose of the measurement, all or a subset of the phenomena on this list may be measured. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the measurement method for current, previously informative, is now normative with some changes;
- the measurement method for RVC (rapid voltage change) has been added;
- the measurement method for conducted emissions in the 2 kHz to 150 kHz range has been added in informative Annex C;
- underdeviation and overdeviation parameters are moved to informative Annex D;
- Class A and Class S measurement methods are defined and clarified, while Class B is moved to informative Annex E and considered for future removal;
- measurement methods continue in this standard, but responsibility for influence quantities, performance, and test procedures are transferred to IEC 62586-2.
The contents of the corrigendum of December 2016 have been included in this copy.

Compatibilité électromagnétique (CEM) - Partie 4-30: Techniques d'essai et de mesure - Méthodes de mesure de la qualité de l'alimentation

IEC 61000-4-30:2015 définit les méthodes de mesure des paramètres de qualité de l'alimentation des réseaux d'énergie électrique en courant alternatif à une fréquence fondamentale déclarée de 50 Hz ou 60 Hz et la façon d'interpréter les résultats. Les méthodes de mesure sont décrites pour chaque paramètre applicable en des termes qui fournissent des résultats fiables et répétitifs indépendamment de la mise en oeuvre de la méthode. La présente norme porte sur les méthodes de mesure destinées aux mesurages in situ. Le mesurage des paramètres couverts par la présente norme se limite aux phénomènes conduits sur les réseaux d'énergie électrique. Les paramètres de qualité de l'alimentation pris en compte dans la présente norme sont la fréquence industrielle, l'amplitude de la tension d'alimentation, le papillotement ("flicker"), les creux et les surtensions temporaires d'alimentation, les coupures de tension, les tensions transitoires , le déséquilibre de tension d'alimentation, les harmoniques et interharmoniques de tension, les signaux transmis sur la tension d'alimentation, les variations rapides de tension et les mesurages de courant. Les émissions dans la plage comprise entre 2 kHz et 150 kHz sont prises en compte dans l'Annexe C (informative), et les valeurs hautes et valeurs basses sont prises en compte dans l'Annexe D (informative). En fonction de l'objet du mesurage, les mesurages peuvent porter soit sur une partie des phénomènes de cette liste, soit sur l'ensemble. Cette troisièm e édition annule et remplace la deuxième édition, parue en 2008. Cetteédition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- la méthode de mesure du courant, précédemment informative, est désormais normative et comporte quelques modifications;
- la méthode de mesure de RVC (rapid voltage change - variations rapides de tension) a été ajoutée;
- la méthode de mesure des émissions conduites dans la plage de 2 kHz à 150 kHz a été ajoutée dans l'Annexe informative C;
- les paramètres de valeur basse et de valeur haute ont été déplacés dans l'Annexe informative D;
- les méthodes de mesure de Classe A et de Classe S sont définies et clarifiées, tandis que la Classe B a été déplacée dans l'Annexe informative E en vue d'un retrait ultérieur;
- les méthodes de mesure se poursuivent dans la présente Norme, mais les responsabilités pour les grandeurs d'influence, les performances et les procédures d'essai ont été transférées dans l'IEC 62586-2.
Le contenu du corrigendum de décembre 2016 a été pris en considération dans cet exemplaire.
