EVALUASI DAN KOORDINASI SETTING RELAI OCR DAN GFR PADA GARDU INDUK NEW JAKABARING
Daftar Isi:
- In the electricity system interconnection in Indonesia, usually usig an open type of conductor in the open space which contains a lot of risk of short circuit interference. The magnitude of the short circuit noise that may occur in an electrical system can damage and disrupt the electricity distribution system equipment. For this reason, an electric power system requires the coordination of a protection system to separate equipment that has been distrupted. From the calculation results obtained at the New Jakabaring Substation of four feeders namely Padjajaran, Kutai, Mataram, Sriwijaya feeders for Overcurrent Relay (OCR) settings on a 150 kV primary side transformer having a TMS of 0,307 SI, a 20 kV secondary side transformer has TMS 0,18 SI, the recipient of Padjajaran has a TMS is 0,07 SI, in the Kutai feeder has TMS 0,11 SI, the Mataram feeder has a TMS of 0,06 SI, and the Sriwijaya feeder has TMS of 0,14 SI. For setting Ground Fault Relay (GFR) on a 150 kV primary side transformer having a TMS of 0,404 SI, a 20 kV secondary side transformer has a TMS of 0,235 SI, Padjajaran feeder, Kutai, Mataram, and Sriwijaya having a TMS of 0,10098
