Star delta starter can be used only for low to high power three phase induction motors. There is minor correction is require to change printed in boxes sequence of 3 phase wires from w2 v2 u2 to w2 u2 v2 to get delta connection properly.
Star Delta Starter Electrical Notes Amp Articles
Star delta starter diagram download. This equipmentappliance reduces starting current and starting torque. Relationship star delta or star delta or wye delta is indeed quite popular as the choice of applications that require the consumption of a small current while the start of the motor is turned on. Refer to the below star delta circuit. Star delta or star triangle series is one of 3 ph electromotor starter systems aimed at minimizing the current spikes that occur when the electro motor is operated starting. Characteristics features of star delta starter. Automatic star delta starter design normally consists of three contactors an overload relay or circuit breaker and a timer for setting the time in the star position starting.
The control circuit uses to control the starter circuit such as on off and tripping operations. The peak starting torque is 33 of full load torque. The starting current is 33 of full load current for star delta starter. The power circuit uses to create contact between the motor and three phase power supply. Star delta starters consist of a power circuit and control circuit.
