Closed Transition Resistor For Star Delta Starter
Brand: Grand Holly
For resistor applications used on Star(Wye)- Delta type motors, (Closed Transition) the resistors are connected to the motor winding before the delta contactor is closed.
The resistors are used to avoid the possibility of high inrush current when the winding is momentarily open – circuited when switching from Star (Wye) to Delta Winding configuration on the motor ,therefore providing a smoother acceleration of the motor.
