Abstract :
To secure from short circuit disturbances that can damage equipment on low voltage networks and medium voltage networks, OCR and GFR are used at PDTM Sky House Alam Sutera Apartments. Therefore, it is necessary to plan the coordination of the protection system for the incoming and outgoing PDTM side so that disturbances that occur on the Sky House Apartment side do not cause a trip to the Honai Feeder. From the study of manual calculations, checking working time to see the selectivity of relay work in coordination, when there is a 3-phase short-circuit fault on the 0.4 kV base LV Bus. OCR outgoing PDTM working time is 0.303 seconds, OCR incoming PDTM is 0.701 seconds, OCR outgoing Honai Feeder is 2.835 seconds. While the results of the simulation ETAP 16.0, OCR outgoing PDTM 0.302 seconds, OCR incoming PDTM 0.700 seconds, OCR outgoing PDTM 2.834 seconds. In the event of a single-phase short-circuit fault to ground on the BUS LV base 0.4 kV, based on the results of manual calculations, GFR outgoing PDTM 0.301 seconds, GFR incoming PDTM, 0.702, outgoing GFR Honai feeder 1.109 seconds. While the results of the ETAP simulation are 16.0, GFR outgoing PDTM 0.378 seconds, GFR incoming PDTM 0.701 seconds, outgoing GFR Honai feeder 1.100 seconds
