标准摘要
[中文适用范围]： 本IEC 62053标准部分仅适用于50 Hz或60 Hz电网中用于测量交流电有功电能的变压器供电式静态电能表，精度等级为0,1S、0,2S和0,5S，且仅适用于其型式试验。该文件适用于设计用于以下目的的电能计量设备：在电压最高达1000 V的电网上测量和控制电能；除指示显示外，所有功能元件（包括附加模块）均 enclosed in或构成单个电表外壳；可配合集成或分离的指示显示使用，或无指示显示；安装在指定的匹配插座或机柜中；可选提供除电能测量之外的其他功能。 [外文原描述]： IEC 62053-22:2020 applies only to transformer operated static watt-hour meters of accuracy classes 0,1 S, 0,2 S and 0,5 S for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only. 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; • have all functional elements, including add-on modules, enclosed in, or forming a single meter case with 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. This document does not apply to: • meters for which the voltage line-to-neutral derived from nominal voltages exceeds 1 000 V AC; • meters intended for connection with low power instrument transformers (LPITs as defined in the IEC 61869 series) when tested without such transformers; • metering systems comprising multiple devices 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) Moved the descriptions of all general requirements and test methods from IEC 62053-21: 2003, IEC 62053-22: 2003, IEC 62053-23: 2003, IEC 62053-24: 2003 to IEC 62052-11:2020; IEC 62053-21:2020, IEC 62053-22:2020, IEC 62053-23:2020, IEC 62053-24:2020 contain only accuracy class specific requirements. c) Added new requirements and tests concerning: 1) active energy meters of accuracy class 0,1S; 2) measurement uncertainty and repeatability (7.3, 7.8); 3) influence of fast load current variations (9.4.12); 4) immunity to conducted differential current disturbances in the 2 kHz to 150 kHz frequency range (9.3.8)
