Auto transformer wiring diagram

Author: John A. Dedad Author: Ricardolevinsmorales Circuit diagrams Autotransformer & part winding Autotransformer – HOA An autotransformer starter reduces inrush current by using a

transformer in the line just ahead of the motor to step down the voltage applied to the motor terminals. By reducing the voltage, the … A ∆ – ∆ autotransformer connection is theoretically possible; however, this will create a peculiar phase shift. The phase shift is a function of the ratio of the primary to secondary voltages and it can be calculated from the vector diagram. Author: Luqman The wiring diagram is above. As you can see, the equitment takes 277/240/208/120V
