| Abstract: | The performance cooperation of two-end directional elements and the transfer cooperation of two-end blocking signals are studied on the basis of the principle and algorithm of transient directional unit using median filtering in this paper. It is concluded that only starting right when fault occurs, directional comparison pilot protection based on transient can discriminate reliably fault in zone. |
