Abstract :
feeder with 20 kV system is a media for distribute electric power from main station to the custumer. But the feeders almost have a disturbance, such as short circuit disturbance. So Is needed a protection system which is fullfill the qualification such as sensitivity, realibity, selectifity, and speed, which all of that depend on the accuration of tool protection setting. In general a used for feeder with 20 kV system are Over Current Relay (OCR) and Ground Fault Relay (GFR), that is relay which has function to make the PMT to open the circuit, medium voltage air/ cable channel which has disturbance separate from network. In this final project will be explained about the coordination between incoming transformator, feeder and medium voltage customer.
