Electricity metering equipment - General requirements, tests and test conditions - Part 31: Product safety requirements and tests

IEC 62052-31:2024 specifies general safety requirements and associated tests, with their appropriate conditions for type testing of directly connected, transformer-operated or transducer-operated AC and DC electricity meters and load control equipment. This document applies to electricity metering equipment designed to: • measure and control electrical energy on electrical networks (mains) with voltage up to 1 000 V AC, or 1 500 V DC; • have all functional elements, including add-on communication modules, enclosed in, or forming a single meter case with exception of indicating displays; • operate with integrated displays (electromechanical or static meters); • operate with detached indicating displays, or without an indicating display (static meters only); • wall-mounted or to be installed in specified matching sockets or racks; • optionally, provide additional functions other than those for measurement of electrical energy. This document also applies to transducer-operated meters or meters designed for operation with Low Power Instrument Transformers (LPIT) or sensors (as defined in the IEC 61869 series). When equipment in scope of this document is designed to be installed in a specified matching socket, then the requirements apply to, and the tests are performed on, equipment installed in its specified matching socket. However, requirements for sockets and inserting / removing the meters from the socket are outside the scope of this document. This document is also applicable to auxiliary input and output circuits, operation indicators, and test outputs of equipment for electrical energy measurement. Equipment used in conjunction with equipment for electrical energy measurement and control may need to comply with additional safety requirements. See also Clause 13. This document does not apply to: • meters rated to operate with voltage exceeding 1 000 V AC, or 1 500 V DC; • metering systems comprising multiple devices physically remote from one another; • portable meters; • meters used in rolling stock, vehicles, ships and airplanes; • laboratory and mobile meter test equipment; • reference standard meters; • conventional or low power instrument transformers; • equipment with solid-state or other non-electromechanical supply and load control switches. The safety requirements of this document are based on the following assumptions: • metering equipment has been installed correctly; • metering equipment is used generally by ordinary persons, including meter readers and consumers of electrical energy. In many cases, it is installed in a way that it is freely accessible. Its terminal covers cannot be removed, and its case cannot be opened without removing seals (if present) and using a tool; • during normal use all terminal covers, covers and barriers providing protection against accessing hazardous live parts are in place; • for installation, configuration, maintenance and repair it may be necessary to remove terminal cover(s), (a part of) the case or barriers so that hazardous live parts may become accessible. Such activities are performed by skilled persons, who have been suitably trained to be aware of working procedures necessary to ensure safety. Therefore, safety requirements covering these conditions are out of the Scope of this document. This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. Please see the foreword of IEC 62052-31 f

Équipement de comptage de l'électricité - Exigences générales, essais et conditions d'essai - Partie 31: Exigences et essais sur la sécurité de produit

IEC 62052-31:2024 spécifie les exigences de sécurité générales et les essais associés, avec leurs conditions appropriées pour les essais de type des compteurs d’électricité en courant alternatif et en courant continu à branchement direct, alimentés par transformateurs ou transducteurs, ainsi que des équipements de pilotage. Le présent document s’applique aux équipements de comptage de l’électricité conçus pour: • mesurer et piloter l’énergie électrique sur les réseaux électriques (secteur) avec une tension allant jusqu’à 1 000 V en courant alternatif ou 1 500 V en courant continu; • avoir tous les éléments fonctionnels, y compris les modules de communication complémentaires, incorporés dans ou formant un boîtier de compteur unique, à l’exception des afficheurs; • fonctionner avec des afficheurs intégrés (compteurs électromécaniques ou statiques); • fonctionner avec des afficheurs séparés ou sans afficheur (compteurs statiques uniquement); • être montés au mur ou installés dans une embase ou un bâti correspondant spécifié; • assurer en option des fonctions autres que celles relatives au comptage de l’énergie électrique. Le présent document s’applique également aux compteurs alimentés par transducteurs ou aux compteurs conçus pour fonctionner avec des transformateurs de mesure de faible puissance (LPIT) ou des capteurs (tels que ceux définis dans la série IEC 61869). NOTE 6 Pour les compteurs conçus pour fonctionner avec des LPIT, seule l’unité de comptage est considérée comme un dispositif à basse tension. Si les LPIT sont assignés pour des tensions supérieures à 1 000 V en courant alternatif ou à 1 500 V en courant continu, la combinaison de l’unité de comptage et des LPIT n’est pas un dispositif à basse tension. Lorsqu’un équipement relevant du domaine d’application du présent document est conçu pour être installé dans une embase correspondante spécifiée, les exigences s’appliquent à l’équipement installé dans son embase correspondante spécifiée et les essais sont réalisés sur cet équipement. Toutefois, les exigences concernant les embases et l’insertion/le retrait des compteurs de l’embase ne font pas partie du domaine d’application du présent document. Le présent document s’applique également aux circuits auxiliaires d’entrée et de sortie, aux indicateurs de fonctionnement et aux sorties d’essai des équipements de mesure de l’énergie électrique. Les équipements utilisés conjointement avec des équipements de mesure et de contrôle de l’énergie électrique peuvent devoir se conformer à des exigences de sécurité supplémentaires. Voir aussi l’Article 13. Le présent document ne s’applique pas: • aux compteurs assignés pour fonctionner avec une tension dépassant 1 000 V en courant alternatif ou 1 500 V en courant continu; • aux systèmes de comptage comprenant plusieurs dispositifs physiquement éloignés les uns des autres; • aux compteurs portatifs; • aux compteurs utilisés dans le matériel roulant, les véhicules, les navires et les avions; • aux équipements de laboratoire et mobiles d’essai de compteurs; • aux compteurs étalons de référence; • aux transformateurs de mesure conventionnels ou de faible puissance; • aux équipements équipés d’auxiliaires de commande d’alimentation et de charge non électromécaniques à semiconducteur ou autres. Les exigences de sécurité du présent document reposent sur les hypothèses suivantes: • l’équipement de comptage a été installé correctement; • l’équipement de comptage est généralemen
