Abstract: In any electrical system, due to overvoltage or over current line--ground fault, line to line fault, line-line-line fault and line-lineline-ground faults occur. The electrical substation is supply the power to the consumers means industries or domestic can have failures due to any of the fault which can be temporary or permanent. These faults lead to damage to the power system equipment. In this work, effort has made to design an reclosing mechanism in case of permanent or temporary fault. The TimerIc-555 has been used to give the time duration of fault. Circuit breaker is used for disconnecting the line at fault instant and connecting on clearance of fault. Reclosing mechanism resets the supply line after small interruption in the event of temporary fault or it remains in tripped condition in case of permanent fault.
