标准摘要
[中文适用范围]： IEC 60060-2:2025 RLV 包含官方 IEC 国际标准及其红线版本。红线版本仅提供英文版，可让您快速轻松地比较官方 IEC 标准与其先前版本之间的所有变化。IEC 60060-2:2025 适用于完整的测量系统及其组件，用于在实验室和工厂测试中测量高压，测试电压包括直流电压、交流电压、雷电和操作冲击电压以及组合和复合电压，如 IEC 60060-1 所述。有关现场测试期间的测量，请参见 IEC 60060-3。本文件中规定的测量不确定度限值适用于 IEC 60071-1 规定的测试等级。本文件的原则也适用于更高等级，但不确定度可能更大。本文件：• 定义所使用的术语；• 描述评估高压测量不确定度的方法；• 规定适用于测量系统的要求； • 描述批准测量系统和检查其组件的方法； • 描述用户证明测量系统满足本文件要求的程序，包括测量不确定度的限值。 第四版取消并取代了 2010 年发布的第三版。此版本是技术修订版。此版本与前一版相比包括以下重大技术变化：a) 更新和改进了总体布局和文本，使标准更易于使用。b) 已修订此文件以使其与 IEC 60060-1 第四版保持一致。c) 扩展了测量不确定度估计的处理。d) 此文件现在适用于在 IEC 60071-1 中规定的所有标准绝缘水平下进行测试的测量系统。e) 对于在 IEC 60071-1 中规定的所有标准绝缘水平下进行测试，标准雷电脉冲电压前沿时间的测量不确定度要求已从 10% 更改为 15%。 f) IEC 60060-1:2010 第三版中定义的操作脉冲参数“峰值时间”已在 IEC 60060-1 第四版中被“波前时间”取代。本文件已做出必要修改以适应 IEC 60060-1 的这一变化。g) 新增了第 10 条“组合电压测量”和第 11 条“复合电压测量”。h) 对 B.1 条进行了重大修订，使其与第 5 条的规定更加一致，包括使用相同的术语。 [外文原描述]： IEC 60060-2:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60060-2:2025 is applicable to complete measuring systems and to their components, used for the measurement of high voltages during laboratory and factory tests with direct voltage, alternating voltage and lightning and switching impulse voltages and combined and composite voltages as specified in IEC 60060-1. For measurements during on-site tests, see IEC 60060-3. The limits on uncertainties of measurements stated in this document apply to test levels stated in IEC 60071-1. The principles of this document apply also to higher levels but the uncertainty can be greater. This document: • defines the terms used; • describes methods to estimate the uncertainties of high-voltage measurements; • states the requirements that apply to measuring systems; • describes the methods for approving a measuring system and checking its components; • describes the procedures by which the user demonstrates that a measuring system meets the requirements of this document, including the limits set for the uncertainty of measurement. This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The general layout and text has been updated and improved to make the standard easier to use. b) This document has been revised to align it with the fourth edition of IEC 60060-1. c) The treatment of measurement uncertainty estimation has been expanded. d) This document is now applicable to measuring systems used in testing at all standard insulation levels specified in IEC 60071-1. e) The measurement uncertainty requirement for the front time of the standard lighting impulse voltage has been changed from 10 % to 15 %, for testing at all standard insulation levels specified in IEC 60071-1. f) The parameter "time-to-peak" of the switching impulse defined in the third edition of IEC 60060-1:2010 has been replaced by "front time" in the fourth edition of IEC 60060-1. Necessary changes have been made in this document to accommodate this change in IEC 60060-1. g) Clause 10, Measurement of combined voltages and Clause 11, Measurement of composite voltages have been added. h) Clause B.1 has been significantly revised to align more closely with the provisions of Clause 5, including using the same nomenclature.
