Outrageous Auto Transformer Circuit Diagram
Working principle of autotransformer the circuit diagram of an auto transformer is shown in figure.
Auto transformer circuit diagram. Autotransformer starter diagram stage 1 at starting auto transformer is star connected by activating star contactor km1 and then the run contactor km2 is closed. B step up auto transformer in both cases step up and step down the winding ab is having n 1 turns is primary winding circuit and winding bc having n 2 turns is secondary winding of the auto transformer. While in auto transformer the primary and the secondary windings are connected magnetically as well as electrically.
The above diagram a shows the connection diagram of step down auto transformer and figure b shows the connection diagram of step up autotransformer. When the start button is pressed a circuit is completed to the coil of main contactor m timer tr and shorting contactor s. Autotransformer starter control circuit diagram the working of the starter is as under.
In an ordinary transformer the primary and the secondary windings are electrically insulated from each other but connected magnetically as shown in the figure below. When the single phase ac supply is connected between a and d terminals and output is taken from c and e terminals this auto transformer will operate as a step down transformer. It shows the elements of the circuit as simplified forms as well as the power and signal links between the gadgets.
The winding ab of total turns n 1 is considered as primary winding. In fact a part of the single continuous winding is common to both primary and secondary. And all these get energized the motor gets supply through the tappings of the autotransformer.
