Abstract Current transformer is one of the key equipment of electric energy conversion, its accuracy will Influence relay protection. Traditional current transformer polarity test has the problem of complex method, long time and low efficiency. This paper designs a new type current transformer polarity tester, which can realize the synchronous switch by wireless communication. The test shows that this tester has the advantage of high accuracy, simple operation and wide application.
