Koordinasi Sistem Proteksi Arus Lebih Pada Penyulang Distribusi 20 kV GI Pauh Limo

Jurnal Nasional Teknik Elektro, 2015
At 20 kV feeder outages typically caused by short circuit. If the adjustment over current relay (OCR) in the incoming or outgoing unfavorable, can cause a total blackout (black out). One of the efforts is by resetting the relay protection in distribution

Optimal Coordination of Directional Overcurrent Relays in Microgrids Considering European and North American Curves

Energies
Protecting AC microgrids (MGs) is a challenging task due to their dual operating modes—grid-connected and islanded—which cause sudden variations in fault currents. Traditional protection methods may no longer ensure network security.
