Directing against the irnperfection of the magnetizing current compensa1ion method by similar Current trans former,a new method for extracting magnetizing current is given in this paper. The constitution of the compenHtor is sirnple, and itsworking area can be enIarged by anti-turn compensation method. With the comprehensive compensator, the accuracy of an0. 5 gred e current trans former can be improved to O- l gred e- and adjustment is convenient. simple and direct.
