EN IEC 62053-41:2024

Electricity metering equipment - Particular requirements - Part 41: Static meters for DC energy (classes 0,5 and 1)

This part of IEC 62053 applies only to static watt-hour meters of accuracy classes 0,5 and 1 for the measurement of DC electrical energy in DC systems, and it applies to their type tests only. NOTE 1 For other general requirements, such as safety, dependability, etc., see the relevant parts of IEC 62052 or IEC 62059. This document applies to electricity metering equipment designed to: - measure and control electrical energy on electrical networks with two poles where one of the poles is connected to earth and with voltage up to 1 500 V DC; NOTE 2 There are DC networks with other configurations or with more than 2 poles (for example networks with earth and both a positive and a negative pole). - have all functional elements, including add-on modules, enclosed in, or forming a single meter case with the exception of indicating displays; - operate with integrated or detached indicating displays, or without an indicating display; - be installed in a specified matching socket or rack; - optionally, provide additional functions other than those for measurement of electrical energy. They may be used for measuring DC electrical energy, amongst others, in the following application areas: - in EV (electrical vehicle) charging stations or in EV charging infrastructures, if the measurement is placed on the DC side; - in information technology (IT) server farms; - in DC supply points for communication equipment; - in low voltage DC networks for residential or commercial areas, if the measurement is placed on the DC side; - in solar PV (photovoltaic) systems where DC power generation is measured; - in DC supply points for public transport networks (e.g. trolleybus, etc.). Meters designed for operation with low power instrument transformers, LPITs as defined in the IEC 61869 series, may be tested for compliance with this document only if such meters and their LPITs are tested together and meet the requirements for directly connected meters. NOTE 3 Modern electricity meters typically contain additional functions such as measurement of voltage magnitude, current magnitude, power, etc.; measurement of power quality parameters; load control functions; delivery, time, test, accounting, recording functions; data communication interfaces and associated data security functions. The relevant standards for these functions may apply in addition to the requirements of this document. However, the requirements for such functions are outside the scope of this document.

Équipement de comptage de l'électricité - Exigences particulières - Partie 41: Compteurs statiques d'énergie en courant continu (classes 0,5 et 1)

IEC 62053:41:2021 est applicable uniquement aux compteurs statiques d'énergie de classes d'exactitude 0,5 et 1, destinés au mesurage de l'énergie électrique en courant continu dans les systèmes en courant continu, et à leurs essais de type. Le présent document s'applique aux équipements de comptage de l'électricité conçus pour: • mesurer et piloter l'énergie électrique sur les réseaux électriques à deux pôles, l'un des pôles étant relié à la terre, de tension jusqu'à 1 500 V en courant continu; • avoir tous les éléments fonctionnels, y compris les modules additionnels, incorporés dans ou formant un boîtier de compteur unique, à l'exception des afficheurs ou dispositifs indicateurs; • fonctionner avec des afficheurs intégrés ou séparés, ou sans afficheur; • être installés dans un rack ou une embase correspondante spécifié(e); • assurer, en option, des fonctions additionnelles autres que celles relatives au comptage de l'énergie électrique. Ils peuvent être utilisés pour le comptage de l'énergie électrique en courant continu notamment dans les domaines d'application suivants: • dans les bornes de recharge pour véhicules électriques ou les infrastructures de recharge pour véhicules électriques, si le mesurage est effectué côté courant continu; • dans les parcs de serveurs des technologies de l'information (TI); • dans les points d'alimentation en courant continu pour les équipements de communication; • dans les réseaux basse tension en courant continu des zones résidentielles ou commerciales, si le mesurage est effectué côté courant continu; • dans les systèmes photovoltaïques (PV) où la puissance générée en courant continu est mesurée; • dans les points d'alimentation en courant continu pour les réseaux de transport public (par exemple, trolleybus, etc.). Les compteurs conçus pour être utilisés avec des transformateurs de mesure de faible puissance (LPIT, Low Power Instrument Transformers, définis dans la série IEC 61869) ne peuvent être soumis à des essais de conformité au présent document que si ces compteurs et leurs LPIT sont soumis ensemble aux essais et satisfont aux exigences relatives aux compteurs à branchement direct. Le présent document ne s'applique pas: • aux compteurs dont la tension entre les deux pôles, l'un des pôles étant relié à la terre, dépasse 1 500 V en courant continu; • aux compteurs prévus pour être utilisés dans des réseaux autres qu'à deux pôles, l'un des pôles étant relié à la terre; • aux compteurs destinés à être connectés à des transformateurs de mesure de faible puissance (LPIT, définis dans la série IEC 61869) lorsqu'ils sont soumis à l'essai sans ces transformateurs; • aux systèmes de comptage qui comprennent plusieurs dispositifs physiquement éloignés les uns des autres (à l'exception des LPIT); • aux compteurs portatifs; • aux compteurs utilisés dans le matériel roulant, les véhicules, les navires et les avions; • aux équipements de laboratoire et d'essai des compteurs; • aux compteurs étalons de référence; • aux interfaces de données avec l'élément indicateur du compteur; • aux racks ou embases correspondantes utilisés pour l'installation des équipements de comptage de l'électricité; • à toute fonction additionnelle assurée par les compteurs d'énergie électrique.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
