Abstract:

This paper presents the protection of 3 phase induction motor by using numerical relay. This project is based on the study of three phase induction motor and its faults and other is study of numerical relay. This protection system is different to others because of numerical relay. Motor is connected to the three phase supply with help of contactor and MCB. Contactor is provided continuous supply to the motor. CT is connected to the numerical relay. When any fault is occurred in the motor at that time relay is sense the fault and sends a tripping signal to the contactor. Contactor opens the contacts and motor is disconnected from supply. Now motor is perfectly protected.
