Differential relay itself is a release that will work to read interference and provide a signal to the CB (PMT) to access the circuit or cut off the inrush. With the research conducted ejection and simulated with ETAP, the results that can show the disturbance of the busbar 150 kV and 20 kV. The use of this simulation can be used in every Power Plant unit so that damage occurs in the reading.} }
