Power transformers - Part 19: Rules for the determination of uncertainties in the measurement of losses in power transformers and reactors
电力变压器第19部分:电力变压器和电抗器损耗测量中不确定度的测定规则
IEC/TS 60076-19:2013, which is a Technical Specification, illustrates the procedures that should be applied to evaluate the uncertainty affecting the measurements of no-load and load losses during the routine tests on power transformers. Even if the attention is especially paid to the transformers, when applicable the specification can be also used for the measurements of reactor losses, except large reactors with very low power factor.
