What is the construction of transformer Class 12?

A transformer is made up of a rectangular iron core. Two coils, a primary (P) coil with two sides P1 and P2, and a secondary (S) coil with two sides S1 and S2. Both these coils are insulated from the Ferro-magnetic iron core.

What are the two types of transformer construction?

There are two general types of transformer construction: core-type and shell-type. Single-phase core-type construction consists of a core that provides a single-path magnetic circuit.

What is the material used for construction of transformer core?

In most types of transformer construction, the central iron core is constructed from of a highly permeable material commonly made from thin silicon steel laminations. These thin laminations are assembled together to provide the required magnetic path with the minimum of magnetic losses.

What is transformer explain the construction and working of transformer?

WORKING PRINCIPLE: Transformer works on the principle of Mutual induction between two windings (Primary and secondary) linked by common magnetic flux. When source of alternating voltage is connected to the Primary coil the magnetic flux produced in primary induces flux in secondary coil too. The frequency remain same.

What is the parts of transformer?

There are four primary parts to the basic transformer. The parts include the Input Connection, the Output Connection, the Windings or Coils and the Core.

What is transformer and its parts?

A transformer is made of several different parts that function in their own different ways to enhance the overall functioning of a transformer. These include core, windings, insulating materials, transformer oil, tap changer, conservator, breather, cooling tubes, Buchholz Relay and explosion vent.

Which is the most widely used material in the core of transformer?

cold rolled grain oriented sheet steel.

What are the 3 basic parts of transformer?

There are three basic parts of a transformer:

• an iron core which serves as a magnetic conductor,
• a primary winding or coil of wire and.
• a secondary winding or coil of wire.

What is explosion valve in transformer?

Explosion Vent of Transformer The purpose of the explosion vent in a transformer is to prevent damage of the transformer tank be releasing any excessive pressure generated inside the transformer.
