Functions of Electrical Transformer
Electrical transformers are used to "transform" voltage from one level to another, usually from a
higher voltage to a lower voltage. They do this by applying the principle of magnetic induction
between coils to convert voltage and or current levels.
In this way, electrical transformers are a passive device which transforms alternating current
(otherwise known as "AC") electric energy from one circuit into another through electromagnetic
induction. An electrical transformer normally consists of a ferromagnetic core and two or more
coils called "windings". A changing current in the primary winding creates an alternating
magnetic field in the core. In turn, the core multiplies this field and couples the most of the flux
through the secondary transformer windings. This in turn induces alternating voltage (or emf) in
each of the secondary coils.
Electrical transformers are used to "transform" voltage from one level to another, usually from a
higher voltage to a lower voltage. After production electrical energy in hydro station the voltage
level is very high because it need to transported with transmission line alone this process they are
losses before it arrives the substation for distribution furthermore it need to be boosted with
transformers which can be power transformer or distributing transformer depending on the area
to be supplied or to travel with the electrical energy
