标准范围

IEC 62053-41:2021仅适用于用于测量直流系统中直流电能的精度等级为0、5和1的静态电度表，并且仅适用于其型式试验。本文件适用于设计用于:？测量和控制两极电网上的电能，其中一极接地，电压高达1 500 V DC；？除指示显示器外，所有功能元件（包括附加模块）都封装在或形成单个仪表外壳中；？在集成或分离式指示显示器的情况下操作，或在没有指示显示器的情况下操作；？安装在指定的配套插座或机架中；？可选地，提供除电能测量之外的附加功能。除其他外，它们可用于在以下应用领域中测量直流电能:？在EV（电动汽车）充电站或EV充电基础设施中，如果测量放置在DC侧；？在信息技术（IT）服务器群中；？在通信设备的直流电源点；？在住宅或商业区的低压直流网络中，如果测量放置在直流侧；？在测量DC发电的太阳能PV(光伏)系统中；？公共交通网络（如无轨电车等）的DC供应点。）.设计用于与IEC 61869系列中定义的低功率互感器（LPIT）一起运行的仪表，只有当此类仪表及其LPIT一起测试并满足直接连接仪表的要求时，才可以测试其是否符合本文件。本文件不适用于:？其中一极接地的两极之间的电压超过1 500 V DC的电表；？用于两极网络（其中一极接地）以外的网络的电表；？在没有低功率仪表变压器（IEC 61869系列中定义的LPIT）的情况下进行测试时，预期与低功率仪表变压器连接的仪表；？包括物理上(除了LPIT)彼此远离的多个设备的计量系统；？便携式仪表；？机车车辆、车辆、船舶和飞机上使用的仪表；？实验室和仪表测试设备；？参考标准仪表；？到仪表的寄存器的数据接口；？用于安装用电计量设备的配套插座或机架；？电能表中提供的任何附加功能。本文件不包括检测和防止损害仪表性能的欺诈企图（篡改）的措施。

IEC 62053-41:2021 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.
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;
？ 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.
This document does not apply to:
？ meters for which the voltage between the two poles, where one of the poles is connected to earth, exceeds 1 500 V DC;
？ meters to be used in networks other than with two poles in which one of the poles is connected to earth;
？ 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 (except LPITs) 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 detection and prevention of fraudulent attempts to compromise a meter’s performance (tampering).
