Studi Implementasi Directional Earth Fault Protection Pada Proteksi Bay Pengh…

ABSTRACT In order to optimize High Voltage Transmission Line Protection when a phase to ground fault occurs with high resistance value is implemented DEF (Directional Earth Fault) as protection feature on Distance Relay to detect this fault. Directional Earth Fault working method uses 3I0 residual neutral current detection related to zero order or negative sequence and 3V0 neutral voltage so…
