# Transformer principle

A transformer works on the principle of the need to know because a transformer is an important device in electrical and electronics. The principle of transformer is highlighted and before that, we know the main parts of transformer.

The transformer works on the principle of three parts

1. Core
The core function of the transformer is to assist in the transfer of magnetic flux. This car is made of many thin sheets. The thickness of a thin sheet is usually 0.5 mm. These sheets are very well laminated with each other.

2. primary winding
The winding through which the alternating current enters the transformer is called the primary winding.

Low voltage side primary winding is for step-up transformers and high voltage side primary winding is for step-down transformers.

3. secondary winding
The winding through which the transformer is connected to the load is called secondary winding. Power is sent to the load through the secondary winding.

In the case of a step-up transformer, there is high voltage side secondary winding and in the case of a step-down transformer, there is high voltage side secondary winding.

### Transformer principle

Under the same magnetic flux of the transformer, two circuits or coils are connected by mutual induction. The two inductive coils are magnetically connected to a uniform laminated core without an electrical connection between the two.

The coils have low reluctance and high-quality inductance. The coil connected to the AC source between the two coils is called the primary coil and the coil connected to the load is called the secondary coil.

As the alternating voltage is applied to any one of the coils of the transformer, the variable current creates a variable magnetic force line in that core which intersects the adjacent coil.

As a result, the coil absorbs the mutual voltage according to Faraday's electronic induction principle.e=\frac{Mdi}{dt}
The voltage of the induced voltage transformer and the process of producing this voltage is called transformer action.

When the circuit is completed by connecting the load to the secondary coil, the current will flow through it.

Thus electrical power is transferred from one circuit to another on the principle of electromagnetic induction.
In other words
The transformer basically works according to Faraday's electrolysis principle.

We know if there is a magnetic field and there is a conductor next to this magnetic field. If there is a corresponding motion between the magnetic field and the conductor, then the voltage is discovered between the conductors.

Which is called EMF or Electro-Motive Force. The transformer basically works according to this basic principle.

The transformer itself has a laminated core and above this core are two coils, one being the primary coil and the other being the secondary. The coil with which AC is connected is called the primary coil. The coil that has a load attached to it is called a secondary coil.

When the primary is supplied, the primary variable magnetic force line is created, which cuts the surrounding secondary, resulting in the discovery of the electromagnetic force in the secondary according to the principle of electromagnetic induction.

This is how power can be transferred from one circuit of the transformer to another. Depending on the voltage and current generated in the secondary, the number of patches in the primary and secondary coils.

Condition monitoring of transformer

1. Electrical energy is transferred from one circuit to another without any electrical connection between the two coils.
2. The frequency of both coils is always the same during the main operation of the transformer.
3.The principle of the transformer works on the principle of electromagnetic induction.
4. The coils of the transformer are magnetically connected by a uniform iron.
5. The voltage and current of the transformer coils depend on the number and size of their patches.
6. The power of both coils of the transformer is always the same.
7. The two electrical circuits of the transformer have a mutual inductive effect on each other.

FAQ In Transformer principle

Q1. What are the other methods of small transformer efficiency?
Ans:- As there is no rotating part of the transformer, it does not cause friction and loss of wind power, which is the case with other machines. Therefore, the efficiency of the transformer and other methods is more than the equipment.

Q2. What is the thickness of the lamination sheets of the transformer?
Ans:- 0.35 mm for 50 Hz frequency and 0.5 mm for 25 Hz frequency.

Q3. What is the voltage and current of the coil of the transformer?
Ans:- Depending on the number and size of wire patches.

Q4What is the composition of the magnetic circuit of a transformer?
Ans:- The magnetic circuit consists of the core, the yoke, and the metal part that connects them.
