AUTOMATIC STAR DELTA STARTER USING RELAY FOR 3PHASE INDUCTION MOTOR

We all know that three phase induction motors draw high value of current during its starting operation as compared to un full load running conditions. Various methods have been developed over years for starting these induction motors with low value of current to reduce the effects of high starting current and the complex starting methods to reduce starting current is often compromised with other unanticipated inrush currents introduced by the starting system itself . This project implements the use of relays and electronic timer which provides low current start to the motor and protects it from inrush currents as well.
