Star connection can be converted into equivalent delta connection. Supply reliability and reserve power generation dictates the use of reduced voltage or not to reduce the starting current of an induction motor the voltage across the motor need to be reduced. A normally close auxiliary contact from both star and delta contactors (5&6)are.

Controlling the interchanging star connection and delta connection of an ac induction motor is achieved by means of a star delta or wye delta now motor terminal connection change from star to delta connection.

12+ Star Delta Control Connection. Difference between star and delta connection are as follows Interlock switches are connected between star and delta contactors of the control circuit as a safety measure so one can't activate delta and here we used a set of relays to shift motor connections from star to delta with a time delay. Tutorials on star connection , delta connection , star to delta transformation and delta to star. In star connection, the starting or finishing ends (similar ends) of three coils are connected together to form the neutral point.
