It shall be observed that, using Auto-Transformer we are only applying a reduced voltage xV 1 to the Stator terminal of Induction Motor. Here x is less than 1. As soon as the Induction Motor reaches its rated speed, full supply voltage is applied to the terminals of stator.

An auto transformer is wound on a torroid core, usually a single wire with a wiper arm sliding along the torroid wound wire. As the neutral wire is common to supply and load, there can be no effec Note that the primary and secondary winding of auto transformer are connected electrically as well as magnetically. Hence Power from the primary is transferred to the secondary winding conductively as well as Transformer action by mutual induction.

Se hela listan på javatpoint.com MES Auto transformers has only one winding. The transformer primary and secondary shared the common winding, voltage required is tapped out along the common winding. Therefore it reduce the size, weight and cost compared to an isolation transformer.An auto transformer are used when there is no required on electrical isolation between the primary power source and the secondary load. Two completely different types of power reduction.

The task of the autotransformers along the catenary line is to balance the voltages between the catenary and the earth, and the negative phase 

The " auto " (Greek for "self") prefix refers to the single coil acting alone, not to any kind of automatic mechanism. In an autotransformer, portions of the same winding act as both the primary winding and secondary winding sides of the transformer.

An Auto Transformer is a transformer with only one winding wound on a laminated core. An auto transformer is similar to a two winding transformer but differ in the way the primary and secondary winding are interrelated. Se hela listan på tronic-controls.com Disadvantages of Auto transformer: There is no electrical isolation between the windings. So grounding the primary of an autotransformer won’t eliminate the risk of an electrical shock as both windings are electrically connected.
