What is Transformer and Its Working Principle

Since the origin of electricity has been started, people have started using it completely. And why do so, because of the many benefits of Electricity. The transformer has a different role in the process of getting electrolytes out of circulation. Probably many people in you know that what is the transformer?

We see many types of the transformer in neighborhood neighborhoods. Some are small in size, some are very large in size. They are used according to their need. There are many people out there who have seen the transformer but they do not know what they do in the work.

Even if the structure of the transformer looks like a monster machine, but you may also be amazed by knowing about its usefulness. If you do not really know anything about these machines, then today's article What Transformers are and how they work is definitely going to be very important for you.

So today I thought why you should be given the complete definition in terms of a transformer, as well as in the context of the same utility, which will help you to understand it correctly. So let's begin without delay.

What is Transformer (Hindi)

Transformer is a device that transfers electrical energy from one circuit to another, through a magnetic field and without any changes in the frequency.

In this, which receives electrical power of the electric circuit source, it is called primary winding and another circuit which gives power energy load is called secondary winding.

Who invented the transformer

Electric Transformer invented by William Stanley in 1885 in the United States. This information is on Wikipedia. It is also said that the invention of the transformer was done by Michael Faraday in 1831 in Britain.

Definition of transformer

If we look at the definition of Transformer, then we will find that it is a device which either steps up the voltage or step-down, according to the corresponding decrease and increase of current also.

What is the Electrical Network and its type
Transformer is actually an electromagnetic energy conversion device, in which the energy is obtained, it is first converted into a primary winding, in magnetic energy and then it is reconverted again on secondary winding in electrical energy.

Which principle does the transformer work on?

If we talk about transformers then it works on the basis of which principle is called the Faraday's Law of Electromagnetic Induction.

According to this principle, "The magnitude of the voltage is directly proportional to the rate of change of flux."

Structure of Transformer

Now let's know about the parts of Transformer.

By the way, there are many parts of the transformer but the most prominent among them are three parts,

Transformer's Primary Winding
Transformer's Magnetic Core
Transformer's Secondary Winding
Primary Winding
This is the primary winding that produces magnetic flux when it is connected with an electric source.

Magnetic Core

The magnetic flux generated in this primary winding is passed to the low reluctance path which is linked to the secondary winding and it creates a closed magnetic circuit.

Secondary Winding

The flux that is generated in the primary winding is passed through the core, which is linked with the secondary winding. This winding is also wrapped in the same core and it also produces the required output of Transformer.

Note It is necessary to understand that the transformers do not generate electricity power; They transfer electrical power from one AC circuit to another, using magnetic coupling.

Transformer's core is used to provide a controlled path to the magnetic flux which is generated in the transformer through the current which is being flowing in the windings, also called coils.

Parts of Transformer

A Basic Transformer has four primary parts. Which are Input Connection, Output Connection, Windings or Coils and Core.

Input Connections
The input side of the transformer is also called the primary side, because the main electrical power that is replaced is connected to this point.

Output Connections
The output side of the transformer or the secondary side is the part where the electrical power is sent to the load. According to the load requirement, incoming electric power is either increased or reduced.

Winding
Transformers have two windings, one is primary winding and the second is secondary winding.
Primary winding is the coil which draws power from the source.

The secondary winding is the coil which gives energy to the load in the transformed or changed voltage. Often these two coils are subdivided in many coils to reduce the formation of flux.

Core
Transformer core is used to provide a controlled path that occurs in the transformer in the magnetic flux that is generated.

This core is not usually a solid bar of steel, but rather a group of very thin laminated steel sheets or layers. It has been made so that due to it the heating can be reduced or completely eliminated.

Transformers generally use one of the two cores described below:

Core Type and Shell Type
Both of these types are different from each other, such as how their primary and secondary coils are wrapped around steel core and around.

Core type - In this type, windings have been surrounded by laminated core.

Shell type - In this type, windings are surrounded by laminated core.

Theory of Transformer
The working principle of transformer is very simple. Mutual induction is used in between two or more windings (also known as coils) which allow electrical energy to be transferred between these circuits.

This principle has been explained in a better way. Let's read it.
