A static electrical device is like a power transformer, one of thefunctions of which is to transfer one power circuit to another circuit, either changing the voltage without having to change the frequency. This paper described a Protection is a system in electricity andhasafunction as an isolate, breaker and separator if there is a disturbance. The working principle of the differential relay is to compare the vector I1 of the primary side current with I2 of the secondary side current. "The results of the mathematical calculation of the setting current for the differential current obtained are 0.0961865394 A and this isdifferent from the setting current installed in the differential relay onthe power transformer of 1 substation, namely 0.3 A."
