Star Delta Starter PDF
is commonly referred to a soft starter or a Star Delta starter. This starter is simply a number of contactors (switches) that connect the different leads together to form the required connection, i.e. Star or Delta.
Star-Delta Starter The conventional way of starting a motor with KW rating more than 10 is usually using a star-delta starter. This is just a thumb rule and may vary according to the designer. The motor starts running with its winding in the star form.
