摘要
标准电能表法常用于电能表检验装置的误差测量。本文叙述了检验电能表检验装置的测量方法,给出了方差、灵敏度和标准偏差的计算公式。并通过对电能表检验装置的误差测试来分析电能表检验装置的测量不确定度,从而给出电能表检验装置的合成标准不确定度和扩展不确定度。
The standard electrical energy meters compared method is application usually to error measurement of the verification equipment for electrical energy meters. We were recount measurement method of the verification equipment for electrical energy meters, were give out to calculated formulas for square-error, sensitivity and standard deviation in the article.We discussed also the measurement uncertainty of verification equipment for electrical energy meters through error measurement of the verification equipment for electrical energy meters,obtained combined standard uncertainty and expanded uncertainty for verification equipment of electrical energy meters.
