Gangguan 1 fasa ke tanah dapat menyebabkan terjadinya gangguan sympathetic trip yang menimbulkan arus urutan nol (arus residu) pada fasa yang terganggu. Penyulang yang memiliki sistem jaringan paralel seperti penyulang Ngurah Rai I dan Ngurah Rai II sangat rentan terjadinya gangguan sympathetic trip, karena relay GFR (Ground Fault Relay) pada penyulang Ngurah Rai I dan Ngurah Rai II tidak bisa mengamankan gangguan tersebut, maka untuk mengatasi gangguan sympathetic trip pada penyulang Ngurah Rai I dan Ngurah Rai II pemasangan relay DGR (Directional Ground Relay) akan mencegah terjadinya gangguan tersebut, dan sistem keandalan penyulang Ngurah Rai I dan Ngurah Rai II tetap terjaga. Hasil analisis perhitungan relay DGR untuk menangani gangguan sympathetic trip didapatkan besar nilai setting relay yaitu = 9.334 A, SI, Waktu trip Arus gangguan t = 0.297, ZCT = 1 A, GPT = 34.64 kV. Jadi untuk mengatasi gangguan sympathetic trip, relay DGR sangat diperlukan jika jaringan atau penyulang beroprasi secara loop dan letaknya berdekatan satu bus.

Disruption of the distribution system is generally caused by a short circuit that causes overcurrent, one single phase short circuit to ground. Single phase to ground disturbances that occurred at the feeder should be secured by a ground fault relays in feeders. However, due to an error of coordination, interference with the feeder perceived also to the incoming side of the transformer so that ground fault relays on the incoming 20 kV ordered PMT 20 kV at the transformer side open. Working time ground fault relays in feeders Peguyangan is for 0.25 seconds. While working time ground fault relays in the incoming 20 kV is for 0.5 seconds. This indicates that differences in work time relay by 0.25 seconds is considered selective. The event of disruption of the ground phase, GFR relay coordination in securing the area of ??interference must be gradual. Where the value of working time ground fault relays in the base should be longer than the time ground fault relays working on a feeder. It aims to work ground fault relays working order, so that errors can be avoided in the security and do not lead to the spread of disturbed areas.
