为了保证电能表检定的准确性,必须对电能表检定装置进行测定,也必须对检定装置的使用及环境条件作出一些规定,以减小对电能表所造成的附加误差。这就是本文所要讨论的问题。一、检定装置的测量误差对检定装置的测定,归根到底,就是为获得装置对电能测量的综合准确度。测定检定装置综合准确度的方法一般有两
In order to ensure the accuracy of the power meter calibration, the power meter calibration device must be measured, and the requirements of the verification device and the environmental conditions must also be specified to reduce the additional error caused by the power meter. This is the issue to be discussed in this article. First, the measurement error of the verification device Determination of the verification device, in the final analysis, is to obtain the overall accuracy of the device on the measurement of electrical energy. There are generally two ways to determine the overall accuracy of the verification device
