| Abstract: | In this paper, the current direct judgment method and practice are expounded. The influence to the fault current direction judgment of the additional phase transposition caused by the non simultaneity of the sequential sample data are analyzed. And as evidence, the conclusion is compared with a objective experiment results. The application feasibility of sequentially data sample method in higher voltage power line protection equipment are pointed out. |
