# BE EEE Project Report On Construction Of Transformer

This BE EEE Project Report On Construction Of Transformer describes the principle and construction of transformer in brief. All parts in transformer are explained like Bushings, Conservator tank, Breather, etc. Transformer is a device used to convert electrical energy from one circuit to another circuit without changing the frequency. This process goes by inductively coupled circuits, which are the coils of the transformer. It consists of two coils, primary and secondary coil.

In Principle of Transformer the report discussed about primary coil and secondary circuit and its works. The transformer is based on two principles: first, that an electric current can produce a magnetic field (electromagnetism), and second that a changing magnetic field within a coil of wire induces a voltage across the ends of the coil (electromagnetic induction). Changing the current in the primary coil changes the magnetic flux that is developed. The changing magnetic flux induces a voltage in the secondary coil. The report also explains the details about the construction of transformer along with the main parts which are used in construction. The main parts of transformer are

1. Core construction. 2. Windings. 3. Bushings. 4. Transformer tank. 5. Conservator tank.                            6. Breather. 7.     Buchholz relay.

A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors called transformer’s coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer’s core and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF), or “voltage”, in the secondary winding. This effect is called mutual induction.

## BE EEE Project Report On Construction Of Transformer Conclusion:

Mainly we use the step up transformer in the power stations and the step down transformers are used in sub stations, distribution stations.  We can design the transformer by using the above points. Each point is briefly explained in the above points. These are the constructional features of the transformer and the main points in the design of the transformer.
