测量不确定度及其在电能表检定中的应用

The Measurement Uncertainty and Application in the Checkup of Energy Meter

在电能表的检定中,除了要给出电能表的示值误差外,同时为了准确表达该示值误差的准确程度,还应给出该值的测量的不确定程度。本文简单阐述了测量不确定度的基本概念及简化估算方法,并结合电能表的检定结果给出评定实例。

During the checkup of energy meter, besides the value error of energy meter, the uncertainty degree of measurement value is also needed in order to show exactitude-degree of value error simultaneity. This paper gives the basic concept of measurement uncertainty and simplified estimation method briefly, and then presents assessed case based on the checkup result of energy meter.
