Star Circuit Diagram. However the resulting networks are only equivalent for voltages and currents external to the star or delta networks as internally the. A dual starter connects the motor terminals directly to the power supply hence the motor is subjected to the full voltage of the power supply consequently high starting current flows through the motor.
A star delta starter is the most commonly used method for the starting of a 3 phase induction motor. Star delta connection diagram and working principle. Star delta starter without timer for 3 phase induction motor.

These circuit transformations allow us to change the three connected resistances or impedances by their equivalents measured between the terminals 1 2 1 3 or 2 3 for either a star or delta connected circuit.
