Anotation

IEC 62052-11:2020 specifies requirements and associated tests, with their appropriate conditions for type testing of AC and DC electricity meters. This document details functional, mechanical, electrical and marking requirements, test methods, and test conditions, including immunity to external influences covering electromagnetic and climatic environments. 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 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); • be installed in a specified matching sockets or racks; • optionally, provide additional functions other than those for measurement of electrical energy. 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 and the relevant IEC 62053 series documents only if such meters and their LPITs are tested together as directly connected meters. This document is also applicable to auxiliary input and output circuits, operation indicators, and test outputs of equipment for electrical energy measurement. This document also covers the common aspects of accuracy testing such as reference conditions, repeatability and measurement of uncertainty. This document does not apply to: • meters for which the voltage line-to-neutral derived from nominal voltages exceeds 1 000 V AC, or 1 500 V DC; • meters intended for connection with low power instrument transformers (LPITs as defined in the IEC 61869 series of standards) when tested without such transformers; • metering systems comprising multiple devices (except of LPITs) physically remote from one another; • portable meters; • meters used in rolling stock, vehicles, ships and airplanes; • laboratory and meter test equipment; • reference standard meters; • data interfaces to the register of the meter; • matching sockets or racks used for installation of electricity metering equipment; • any additional functions provided in electrical energy meters. This document does not cover measures for the detection and prevention of fraudulent attempts to compromise a meter’s performance (tampering). This second edition cancels and replaces the first edition published in 2003, and its amendment 1:2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Removed all meter safety requirements; the meter safety requirements are covered in IEC 62052-31:2015; b) Included requirements for meter power consumption and voltage requirements from IEC 62053-61; IEC 62053-61 is withdrawn; c) Included requirements for meter symbols from IEC 62053-52; IEC 62053-52 is withdrawn; d) Included requirements for meter pulse output devices from IEC 62053-31; IEC 62053-31 is withdrawn; e) Added new requirements and tests including: meters with detached indicating displays, and meters without indicating displays, meter sealing provisions; measurement uncertainty and repeatability; time-keeping accuracy; type test report f) Updated and clarified acceptance criteria for testing of external influences; g) Revised and updated tests for immunity to electromagnetic influences and disturbances as per the latest editions of the basic EMC publications. IEC 62052-11:2020 specifie les exigences et essais correspondants, ainsi que leurs conditions appro-priees, pour les essais de type des compteurs delectricite en courant alternatif et en courant continu. Le present document decrit les exigences fonctionnelles, mecaniques, electriques et de marquage, les methodes dessai et les conditions dessai, y compris en ce qui concerne limmunite aux influences externes, couvrant les environnements electromagnetiques et climatiques. Le present document sapplique aux equipements de comptage de lelectricite concus pour: • mesurer et piloter lenergie electrique sur les reseaux electriques (secteur) de tension jusqua 1 000 V en courant alternatif ou 1 500 V en courant continu; • avoir tous les elements fonctionnels, y compris les modules complementaires, incorpores dans ou formant un boitier de compteur unique, a lexception des af-ficheurs; • fonctionner avec des afficheurs integres (compteurs electromecaniques ou sta-tiques); • fonctionner avec des afficheurs separes ou sans afficheur (compteurs sta-tiques); • etre installes dans une embase ou un bati correspondant specifie; • assurer, en option, des fonctions autres que celles relatives au comptage de lenergie electrique. Les compteurs concus pour etre utilises avec des transformateurs de mesure de faible puissance (LPIT, Low Power Instrument Transformer, definis dans la serie IEC 61869) ne peuvent etre soumis a des essais de conformite au present document et aux docu-ments pertinents de la serie IEC 62053 que si ces compteurs et leurs LPIT sont soumis a lessai ensemble comme des compteurs a branchement direct. Le present document ne sapplique pas: • aux compteurs dont la tension phase-neutre deduite des tensions nominales de-passe 1 000 V en courant alternatif ou 1 500 V en courant continu; • aux compteurs destines a etre connectes a des transformateurs de mesure de faible puissance (LPIT, definis dans la serie de normes IEC 61869) lorsquils sont soumis a lessai sans ces transformateurs; • aux systemes de comptage comprenant plusieurs dispositifs (sauf des LPIT) physi-quement eloignes les uns des autres; • aux compteurs portatifs; • aux compteurs utilises dans le materiel roulant, les vehicules, les navires et les avions; • aux equipements de laboratoire et dessai des compteurs; • aux compteurs etalons de re
