Question

What are the applications of transformers?

Answer 1

Definition

A device that distributes electric energy from one alternating-current (AC) circuit to one or more other circuits, either by raising or decreasing the voltage is called a transformer.

Applications of transformer

1. Transformers are being used in electrical power engineering to transform power from either a produced voltage of roughly $11\mathrm{kV}$ to higher values of $132\mathrm{kV},220\mathrm{kV},400\mathrm{kV},500\mathrm{kV},$ and $765\mathrm{kV}$. As a result, vast volumes of power may be sent across great distances to appropriate distribution sites while saving a lot of money on transmission line costs as well as power failure.
2. Transformers have been employed at distribution centers to decrease this high voltage toward a comfortable limit of $\raisebox{1ex}{$400$}\!\left/ \!\raisebox{-1ex}{$300$}\right.$ volts for usage throughout households, offices, etc.
3. Transformers are indeed employed in telecommunication as well as instrumentation circuits, as well as control circuits.
4. Input transformers, interstage transformers, as well as outputting transformers are commonly used in radio and television circuits.

Therefore, circuit transformers are being used in electric communication for a variety of functions, including impedance modification to allow maximum power transmission from either the input circuit toward the external device.
