초록
Abstract - A new ground fault protective relay scheme, ground fault protective relay, that can identify the faulted region is presented in this paper. In ground fault protective relaying scheme, ground fault is detected by 59, faulted feeder is preselected by comparing among feeder currents and corrected by breaker reclosing operation. Ground switch is employed to obtain sufficient fault current. The relay is modeled and its behavior is simulated using EMTP-RV
