The main objective of protective relay coordination technique in an interconnected one or more power system of transmission and distribution processes is to provide system stability and line voltage stability, also provides voltage regulation. In the protection system in which protective relay are used to protect the transmission line, connected other electrical equipment and human injury. The protective relay operates when internal and external fault is occurred in power system. The relay which operates through over current and earth fault in accordance with setting value of relay plug setting multiplier (current setting) and time multiplier setting.
