标准摘要
[中文适用范围]： 本部分IEC 60076定义了在电力变压器例行测试中评估影响空载和负载损耗测量的不确定性的程序。 本文件主要关注使用数字仪器的测量系统，尽管这些程序可以适用于评估使用模拟仪器的系统，其中需要考虑更多的不确定性来源。 本文件规定了如何确定测量不确定性以及如何对测量链中的已知误差进行校正。关于判断和可追溯性的信息见IEC 60076-8:1997,10.1和10.2。 [外文原描述]： IEC 60076-19-1:2023 defines the procedures that are applied to evaluate the uncertainty affecting the measurements of no-load and load losses during the routine tests on power transformers. This document centres on measuring systems utilizing digital instruments, although the procedures can be adapted to evaluation of systems with analogue instruments where further uncertainty sources have to be taken into account. This document specifies how to determine measurement uncertainty and how to apply corrections for known errors in the measurement chain. Information vis-à-vis judgement and traceability are given in IEC 60076-8:1997, 10.1 and 10.2.
