Electrical safety in low voltage distribution systems up to 1 000 V AC and 1 500 V DC - Equipment for testing, measuring or monitoring of protective measures - Part 12: Power metering and monitoring devices (PMD)
IEC 61557-12:2018 is available as IEC 61557-12:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61557-12:2018 specifies requirements for power metering and monitoring devices (PMD) that measure and monitor the electrical quantities within electrical distribution systems, and optionally other external signals. These requirements also define the performance in single- and three-phase AC or DC systems having rated voltages up to 1 000 V AC or up to 1 500 V DC. These devices are fixed or portable. They are intended to be used indoors and/or outdoors. Power metering and monitoring devices (PMD), as defined in this document, give additional safety information, which aids the verification of the installation and enhances the performance of the distribution systems. The power metering and monitoring devices (PMD) for electrical parameters described in this document are used for general industrial and commercial applications. This document does not address functional safety and cyber security aspects. This document is not applicable for: – electricity metering equipment that complies with IEC 62053-21, IEC 62053-22, IEC 62053-23 and IEC 62053-24. Nevertheless, uncertainties defined in this document for active and reactive energy measurement are derived from those defined in IEC 62053 (all parts); – the measurement and monitoring of electrical parameters defined in IEC 61557-2 to IEC 61557-9 and IEC 61557-13 or in IEC 62020; – power quality instrument (PQI) according IEC 62586 (all parts); – devices covered by IEC 60051 (all parts) (direct acting analogue electrical measuring instrument). IEC 61557-12:2018 cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) PMD-A has been withdrawn due the fact these devices are now mainly covered by the IEC 62586 series of standards. b) Three categories of PMD have been created with a list of minimum required functions for each category. c) Added a new Annex A explaining the different applications linked to the relevant standards and devices, and another new Annex C about the power factor conventions.

IEC 61557-12:2018 est disponible sous forme de IEC 61557-12:2018 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 61557-12:2018 spécifie des exigences relatives aux dispositifs de comptage et de surveillance du réseau électrique (PMD) qui mesurent et surveillent les grandeurs électriques dans les réseaux de distribution électrique et, facultativement, d’autres signaux externes. Ces exigences définissent également les performances dans les réseaux alternatifs ou continus monophasés et triphasés ayant des tensions assignées inférieures ou égales à 1 000 V en courant alternatif ou inférieures ou égales à 1 500 V en courant continu. Ces dispositifs sont fixes ou portables. Ils sont destinés à être utilisés à l’intérieur et/ou à l’extérieur. Les dispositifs de comptage et de surveillance du réseau électrique (PMD) tels que définis dans le présent document donnent des informations supplémentaires sur la sécurité, ce qui facilite la vérification de l'installation et augmente les performances des réseaux de distribution. Les dispositifs de comptage et de surveillance du réseau électrique (PMD) relatifs aux paramètres électriques décrits dans le présent document sont utilisés pour des applications industrielles et commerciales générales. Le présent document ne traite pas des aspects liés à la sécurité fonctionnelle et à la cybersécurité. Le présent document n’est pas applicable: – aux appareils de comptage d’électricité conformes à l’IEC 62053-21, à l’IEC 62053-22, à l’IEC 62053-23 et à l’IEC 62053-24. Néanmoins, les incertitudes définies dans le présent document pour le mesurage de l’énergie active et réactive sont tirées de celles définies dans l'IEC 62053 (toutes les parties); – au mesurage et à la surveillance des paramètres électriques définis dans l'IEC 61557-2 à l'IEC 61557-9 et dans l'IEC 61557-13 ou dans l’IEC 62020; – aux instruments de qualité de l’alimentation (PQI – power quality instrument) conformes à l'IEC 62586 (toutes les parties); – aux dispositifs relevant des domaines d’application de l'IEC 60051 (toutes les parties) (appareils de mesure électriques analogique à action directe). L'IEC 61557-12:2018 annule et remplace la première édition parue en 2007. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) Suppression des PMD-A du fait que ces dispositifs sont à présent largement couverts par la série de normes IEC 62586. b) Création de trois catégories de PMD accompagnées d’une liste des fonctions minimales exigées pour chacune des catégories. c) Ajout d’une nouvelle Annexe A décrivant les différentes applications associées aux normes et dispositifs correspondants et d’une autre nouvelle Annexe C portant sur les conventions du facteur de puissance.

Relationship between this European standard and the safety
objectives of Directive 2014/35/EU [2014 OJ L96] aimed to be
covered
This European Standard has been prepared under a Commission’s standardization request relating to
harmonized standards in the field of the Low Voltage Directive, M/511, to provide one voluntary means
of conforming to safety objectives of Directive 2014/35/EU of the European Parliament and of the
Council of 26 February 2014 on the harmonization of the laws of the Member States relating to the
making available on the market of electrical equipment designed for use within certain voltage limits
[2014 OJ L96].
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZZ.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding safety objectives of
that Directive, and associated EFTA regulations.
