电子式互感器校验仪的研究

摘要

通过比较传统互感器与电子式互感器的区别，提出电子式互感器校验原理及其系统组成，并经现场实测，证实该校验仪精度达到万分之五，能满足对电子式互感器比差和角差测量要求。%In this paper, the working principle and composition of an electronic transformer calibration instrument are put forward. The measured results show that the aecumey of the instrument reaches 5/10000, and can meet the measurement requirement of elec- tronic transformera.
