高压试验技术.第2部分:测量系统

[中文适用范围]： IEC 60060 的这一部分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期间测量 IEC 60060-1 中规定的直流电压、交流电压以及雷电和开关脉冲电压。有关现场测试期间的测量，请参阅 IEC 60060-3。本标准中规定的测量不确定度限制适用于 IEC 60071-1:2006 中规定的测试水平。本标准的原则也适用于更高级别，但不确定性可能更大。本标准： · 定义了所使用的术语； · 描述估计高压测量不确定度的方法； · 说明测量系统应满足的要求； · 描述批准测量系统和检查其组件的方法； · 描述了用户证明测量系统满足本标准要求的程序，包括测量不确定度的限值。 [外文原描述]： IEC 60060-2:2010 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 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 standard apply to test levels stated in IEC 60071-1:2006. The principles of this standard apply also to higher levels but the uncertainty may be greater. This standard also defines the terms used, methods to estimate the uncertainties of high-voltage measurements, states the requirements which the measuring systems shall meet, describes the methods for approving a measuring system and checking its components and describes the procedures by which the user shall show that a measuring system meets the requirements of this standard, including the limits set for the uncertainty of measurement. This third edition cancels and replaces the second edition, published in 1994, and constitutes a technical revision. The significant technical changes with respect to the previous edition are as follows: - The general layout and text was updated and improved to make the standard easier to use. - The standard was revised to align it with IEC 60060-1. - The treatment of measurement uncertainty estimation has been expanded.
