CIRCUIT DIAGRAM OF AUTO TRANSFORMER STARTER
What is Auto-transformer Starter,Working principle,diagram
Mar 05, 2021Stage 1 - At starting auto-transformer is star-connected by activating Star contactor KM1, and then the Run contactor KM2 is closed. This arrangement start an induction motor with reduced voltage and the value of voltage depends upon the ratio of tap selected. The standard taps are 50%, 65% and 80% of the full line voltage Stage 2 - After the preset time delay, the Star contactor KM1 is opened

Advantages of Auto-transformer Starter Due to the availability of different tappings, the autotransformer starter is a more flexible option than the other starters. Therefore, the user can select the best tapping according to the need of starting torque and local conditions like voltage and voltage dip during the commissioning of the starter.

Explanation of Auto Transformer with Circuit Diagram. 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. While in auto transformer the primary and the secondary windings are connected magnetically as well as electrically.
Autotransformer Starter: A reduced voltage motor starting
Aug 03, 2019Autotransformer starter circuit Autotransformer starter equivalent circuit Line current with auto transformer is reduced quadratically in proportion to the tap setting of auto transformer. A 50% tap will reduce line current by 25%.
