A star delta is used for a cage motor designed to run normally on the delta connected stator winding. A dual starter connects the motor terminals directly to the power supplyhence the motor is subjected to the full voltage of the power supplyconsequently high starting current flows through the motor. A star delta starter is a type of reduced voltage starterwe use it to reduce the starting current of the motor without using any external device or apparatus. Size of each part of star delta starter 1 size of over load relay.
Star delta starter the star delta starter is a very common type of starter and is used extensively as compared to the other type of starting methods of the induction motor. This is a big advantage of a star delta starter as it typically has around 13 of the inrush current compared to a dol starter.
