SISTEM KOORDINASI PROTEKSI PEMUTUS TENAGA (PMT) DENGAN PENUTUP BALIK OTOMATIS (PBO) PENYULANG BANTUL 6 DI PT. PLN (PERSERO) RAYON BANTUL

Fault is a problem that often arises in the distribution of electric power. Fault caused by various reasons can cause a lot of damage, loss of electricity transmission systems and losses in the electrical energy consumers. One way to overcome these problems is to install protective devices on the electricity distribution network. Starting from the fuse, behind cover auto reclosers, to overcurrent relay and ground fault relay that works with Circuit Breaker should coordinate to secure the distribution of electric power. Hopefully with sistem protection coordination in the distribution network can suppress the short circuit phase to ground and phase-phase short circuit fault current rise in the amount exceeds the current setting of the overcurrent relays, so relays overcurrent circuit breaker trigger work force in accordance with the time setting is applied , so the risk of damage in electrical distribution system can be avoided.
