Why auto transformer is used in transmission and distribution?

Auto-transformer is used in the transmission and distribution systems when the transformation ratio for voltage is small. The rating of the transformer and copper saving can be maximized when the transformation ratio is low, i.e. lower than 2.

What are 2 types of transformers?

There are two types of potential transformers; the conventional wound type (or electromagnetic type) and the capacitor voltage (potential) transformer. For voltages exceeding 100 kV (phase) the conventional type of potential transformer becomes extremely expensive owing to the insulation requirements.

What devices use transformers?

Transformers are employed for widely varying purposes; e.g., to reduce the voltage of conventional power circuits to operate low-voltage devices, such as doorbells and toy electric trains, and to raise the voltage from electric generators so that electric power can be transmitted over long distances.

How are transformers used?

Transformers are most commonly used for increasing low AC voltages at high current (a step-up transformer) or decreasing high AC voltages at low current (a step-down transformer) in electric power applications, and for coupling the stages of signal-processing circuits.
