标准电能表检定结果的测量不确定度评定

Measurement Uncertainty Evaluation of Standard Electricity Meter Verification Result

介绍标准电能表检定结果的测量不确定度评定方法,以三相四线57.7 V/5 A和三相三线100 V/5 A为例,对0.01级三相电能表标准装置检定0.05级标准电能表的各不确定度分量进行评定,得出评定结果。

This paper introduces the measurement uncertainty evaluation method of verification result of standard watt-hour meter,taking three-phase four-wire 57.7 V/5 A and three-phase three-wire 100 V/5 A as examples, evaluates every partial uncertainty of 0.01 class three phase watt-hour meter standard equipment meter,and gets the checks 0.05 class three phase watt-hour result of evaluation.
