Power quality measurement in power supply systems - Part 2: Functional tests and uncertainty requirements (IEC 62586-2:2013)

EN IEC 62586-2 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 standard applies to power quality instruments complying with IEC 62586-1. This standard may 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 a.c. power supply systems at 50 Hz or 60 Hz.

Mesure de la qualité de l'alimentation dans les réseaux d'alimentation - Partie 2: Essais fonctionnels et exigences d'incertitude (CIE 62586-2:2013)

L'IEC 62586-2:2013 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'énergie dans les réseaux d'alimentation et dont les méthodes de mesure (classe A ou classe S) sont définies dans la norme IEC 61000-4-30. La présente norme s'applique aux instruments de qualité de l'alimentation qui respectent la norme IEC 62586-1. Cette norme peut également apparaître sous forme de référence dans d'autres normes de produits (par ex. enregistreurs de défauts numériques, appareils de mesure des revenus, relais de protection MV ou HV) spécifiant des appareils incorporant des fonctions de qualité de l'énergie de classe A ou de classe S selon la norme IEC 61000-4-30. Ces exigences sont applicables aux réseaux d'alimentation simple, double- (phase divisée) et triphasée c.a. à 50 Hz ou 60 Hz.

Merjenje kakovosti električne energije v napajalnih sistemih - 2. del: Zahteve za funkcionalne preskuse in negotovost (IEC 62586-2:2013)

Standard EN IEC 62586-2 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 standard se uporablja za instrumente za kakovost napajanja v skladu s standardom IEC 62586-1. Na ta standard 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.
