Why is a Star-Delta Starter used?
A Star-Delta Starter is used to reduce the high starting current of a 3-phase induction motor.
By starting the motor in the star connection and then switching to the delta connection, it limits inrush current, minimizes voltage drop, reduces mechanical stress, and extends motor life.
It is a simple and cost-effective starting method widely used for pumps, fans, blowers, compressors, conveyors, and other industrial machines.
