why do we need transformers?

Answer Posted / durgak

To know the need of Transformer we must know what
Transformer does. It is a static device which transforms
the voltage (electromagnetically).In certain cases the
required voltage of a system needs to be increased or
decreased,so in those cases a step up/ step down
transformer is a must required.

Secondly it may be called as a protection device to the
electrical network. At times due to heavy electrical faults
it trips by keeping the main supply system healthy.

To know more in detail about Transformers please refer Book
on Electrical Machines...by M.G.Say......
