Advantage & Disadvantage of Auto Transformer over Two Winding Transformer

Advantage of Auto Transformer: The weight of conductor for any winding depends upon two parameters: Current carried by the winding Number of turns required in the winding Thus we can say that weight of conductor in a winding is directly proportional to its Ampere Turns i.e. MMF. Now, we will focus our attention on the … Read more

Basic Principle of Auto Transformer

A Transformer, in which a part of the winding is common to both the Primary and Secondary circuit is called an Auto Transformer. It shall be noted that in Two Winding Transformer, Primary and Secondary windings are electrically isolated but in Auto Transformer, the two windings are not electrically isolated.A simplified diagram of a Step-down Auto Transformer is … Read more
