What is Transformer

What is Transformer ?

Transformer is a static electric device which transfer the electric energy from one circuit to other without changing the frequency and power. The three-phase synchronous generator is used extensively to generate bulk power. The voltage levels at which this power is generated is typically in the range 11 kV to 22 kV. Electrical power is to be provided at a considerable distance from a generating station.It is possible to transmit the generated power directly but this results in unacceptable power losses and voltage drops.Transmission voltages vary up to the 400 kV level. This is made possible by power transformers.
