Will someone please help me understand the significance of shorting an auto transformer? This feeds a motor. At reduced voltage, the motor starts at 65% of line voltage, a run contactor pulls in bypassing the transformer and the shorting contactor pulls into take the transformer out of the circuit.
How does this happen? What is the significance of shorting them out? Why is it necessary? And what if they were left open? If anyone can explain in detail I would greatly appreciate it!
Thanks!
