供电系统中的电能质量测量. 第2部分: 功能试验和不确定性要求

[中文适用范围]： IEC 62586 的这一部分规定了仪器的功能测试和不确定度要求，这些仪器的功能包括测量、记录和可能监视供电系统中的电能质量参数，其测量方法（A 类或 S 类）在 IEC 61000-4- 中定义。 30.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、计费表、中压或高压保护继电器）引用，这些标准指定了根据 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）和三相交流电源系统。本文档的目的不是解决与设备测量性能无关的用户界面或主题。该文件不包括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 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.
