IEC 60076-19-1:20 23定义了用于评估电力变压器常规测试期间影响空载和负载损耗测量的不确定性的程序。 本文件以使用数字仪器的测量系统为中心，尽管该程序可以适用于使用模拟仪器的系统的评估，其中必须考虑进一步的不确定性来源。 本文件规定了如何确定测量不确定度以及如何对测量链中的已知误差进行校正。IEC 60076-8:19 97，10.1和10.2中给出了有关判断和可追溯性的信息。

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.
