Power quality measurement in power supply systems - Part 2: Functional tests and uncertainty requirements

IEC 62586-2:2017(E) specifies functional tests and uncertainty requirements for instruments whose functions include measuring, recording, and possibly monitoring power quality parameters in power supply systems, and whose measuring methods (class A or class S) are defined in IEC 61000-4-30. This document applies to power quality instruments complying with IEC 62586-1. This document can also be referred to by other product standards (e.g. digital fault recorders, revenue meters, MV or HV protection relays) specifying devices embedding class A or class S power quality functions according to IEC 61000-4-30. These requirements are applicable in single-, dual- (split phase) and 3-phase AC power supply systems at 50 Hz or 60 Hz. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - test procedures for RVC and current have been added; - mistakes have been fixed.

Messung der Spannungsqualität in Energieversorgungssystemen - Teil 2: Funktionsprüfungen und Anforderungen an die Messunsicherheit

Mesure de la qualité de l'alimentation dans les réseaux d'alimentation - Partie 2: Essais fonctionnels et exigences d'incertitude

L'IEC 62586-2:2017 spécifie les essais fonctionnels et les exigences d'incertitude pour les instruments dont les fonctions incluent la mesure, l'enregistrement et, éventuellement, la surveillance des paramètres de qualité de l'alimentation dans les réseaux d'alimentation, et dont les méthodes de mesure (classe A ou classe S) sont définies dans l'IEC 61000-4-30. La présente norme s'applique aux instruments de qualité de l'alimentation conformes à l'IEC 62586-1. Cette norme peut également apparaître sous forme de référence dans d'autres normes de produits (p. ex. sur les enregistreurs de défauts numériques, les appareils de mesure des revenus, les relais de protection MV ou HV) spécifiant des appareils incorporant des fonctions de qualité de l'alimentation de classe A ou de classe S selon l'IEC 61000-4-30. Ces exigences sont applicables aux réseaux d'alimentation en courant alternatif monophasés, biphasés (phase divisée) et triphasés à 50 Hz ou 60 Hz. Cette deuxième édition annule et remplace la première édition parue en 2013. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - ajout des procédures d'essai des RVC et du courant; - correction d'erreurs. La présente version bilingue (2017-11) correspond à la version anglaise monolingue publiée en 2017-03. La version française de cette norme n'a pas été soumise au vote.

Merjenje kakovosti električne energije v napajalnih sistemih - 2. del: Zahteve za funkcionalne preskuse in negotovost (IEC 62586-2:2017)

Standard IEC 62586-2:2017(E) določa zahteve za funkcionalne preskuse in negotovost za instrumente, katerih funkcije zajemajo merjenje, beleženje in morebitno nadzorovanje parametrov kakovosti električne energije v napajalnih sistemih ter katerih merilne metode (razred A ali razred S) so določene v standardu IEC 61000-4-30.
Ta dokument se uporablja za instrumente za kakovost napajanja v skladu s standardom IEC 62586-1.
Na ta dokument se lahko sklicujejo tudi drugi standardi za proizvode (npr. za digitalne snemalnike okvar, merilnike dohodka, srednjenapetostne in visokonapetostne zaščitne releje), ki opredeljujejo naprave s funkcijami kakovosti napajanja razreda A ali razreda S v skladu s standardom IEC 61000-4-30.
Te zahteve se uporabljajo v enofaznih, dvofaznih (razdeljena faza) in trifaznih izmeničnih napajalnih sistemih pri 50 Hz ali 60 Hz.
Druga izdaja razveljavlja in nadomešča prvo izdajo, objavljeno leta 2013. Ta izdaja je tehnično popravljena izdaja. Ta izdaja vključuje naslednje znatne tehnične spremembe glede na prejšnjo izdajo:
– dodani so preskusni postopki za RVC in tok;
– napake so popravljene.
