Korndörfer autotransformer starter In electrical engineering, the Korndorfer starter is a technique used for reduced voltage soft starting of induction motors.The circuit uses a three phase autotransformer and three three phase switches. This motor starting method has been updated and improved by Hilton Raymond Bacon. Autotransformer Connection Explained EEP 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. This phase shift cannot be changed or eliminated and for this reason, autotransformers are very seldom connected as ∆ – ∆ transformers. Electrical Fact Autotransformer starter working, wiring and control diagram: There are various starter used to start induction motor like Direct online starte r , Soft starter , s tar delta starter ,auto tr… What is an Auto Transformer?
