标准摘要
[中文适用范围]： 本部分IEC 62586规定了功能测试和不确定性要求，适用于测量、记录和可能监测供电系统中电能质量参数的仪器，其测量方法（A类或S类）在IEC 61000-4-30中定义。 本文件适用于符合IEC 62586-1的电能质量仪器。 本文件也可被其他产品标准（例如数字故障记录仪、计费电表、MV或HV保护继电器）引用，这些标准规定了根据IEC 61000-4-30嵌入A类或S类电能质量功能的设备。 这些要求适用于50 Hz或60 Hz的单相、双相（分相）和三相交流供电系统。 本文件不涉及用户界面或与设备测量性能无关的主题。 本文件不涵盖数据的后处理和解释，例如使用专用软件。 [外文原描述]： IEC 62586-2:2017+A1:2021 specifies functional tests and uncertainty requirements for instruments whose functions include measuring, recording, and possibly monitoring power quality parameters in power supply systems, and whose measuring methods (class A or class S) are defined in IEC 61000-4-30. This document applies to power quality instruments complying with IEC 62586-1. This document can also be referred to by other product standards (e.g. digital fault recorders, revenue meters, MV or HV protection relays) specifying devices embedding class A or class S power quality functions according to IEC 61000-4-30. These requirements are applicable in single-, dual- (split phase) and 3-phase AC power supply systems at 50 Hz or 60 Hz. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - test procedures for RVC and current have been added; - mistakes have been fixed. The contents of the corrigendum of June 2018 have been included in this copy.
