标准范围

IEC 62053-24:20 20仅适用于精度等级为0、5S、1S、1、2和3的静态可变小时计，用于测量50 Hz或60 Hz网络中的交流无功功率，并且仅适用于其型式试验。该文件使用无功功率的常规定义，其中无功功率和能量仅由电流和电压的基频分量计算。本文件适用于设计用于:？测量和控制电压高达1 000 V AC的电网（市电）上的电能；？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。设计用于与低功率互感器（IEC 61869系列中定义的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，才可视为符合本文件。本文件不适用于:？从标称电压得出的线到中性线的电压超过1 000 V AC的仪表；？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；？包括物理上彼此远离的多个设备(LPIT除外)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预防损害仪表性能的欺诈企图（篡改）的措施。本第二版取消并取代2014年出版的第一版及其修正案1:20 16。本版构成技术修订版。与上一版相比，本版本包括以下重大技术变更:见附录E

IEC 62053-24:2020 applies only to static var-hour meters of accuracy classes 0,5S, 1S, 1, 2 and 3 for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only.
This document uses a conventional definition of reactive energy where the reactive power and energy is calculated from the fundamental frequency components of the currents and voltages 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.
Meters designed for operation with low power instrument transformers (LPITs as defined in the IEC 61869 series) may be considered as compliant 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 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 (except 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 2014 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: see Annex E
