First, I will discuss the applications of the transformer. Nowadays, transformers are used in every sector it may be schools, hospitals, colleges, in electronics devices, stations, etc, the transformer will give us the desired voltage as per our requirement, if we want an output of 12V then 12V transformers are also available in the market. Transformers are like a heart in a power system.
What Is A Transformer
A transformer is a device or equipment which is in a static position with no moving parts, the purpose of a transformer is to transform voltage from one level to another level without changing frequency and power. If we use a step-down transformer then the transformer will step down the voltage i.e., reduces the voltage. There are many different types of transformer are used nowadays like power transformer, distribution transformer, instrument transformer, etc.
Working Of A Transformer
The transformer always works on the bases or principle of mutual induction. Mutual induction says that when two coils(single-phase transformer) are coupled inductively then the current in one coil if it is changed uniformly then the emf (electromotive force) induce in another coil.
Let’s talk about a single-phase transformer, the transformer mainly consists of two coils or two winding, the winding which is connected to the supply to draw energy is called primary winding whereas the winding which is connected to load is called secondary winding.
When alternating supply is given to the transformer, the alternating flux will be produced in the transformer, this alternating flux completes its path through the magnetic core and then alternating flux links with the secondary winding of the transformer. According to Faraday’s law, whenever coil links with the conductor or vice-versa, the emf will be induced.
This is how the transformer works.
Will Transformer Works On DC Supply
No, the transformer will not work on dc supply because the transformer needs alternating flux but when we connect dc supply it will produce steady flux. So there is a chance of burning a transformer when we connect the dc supply to it.
Parts Of A Transformer
The main parts of the transformer are:
- 01. Core
- 02. Limb
- 03. Yoke
- 04. Windings
- 05. Conservator
- 06. Breather
- 07. Explosion Vent
- 08. Buchholz Relay
Now I will explain step by step each part working.
01. Core – The function of the core is to carry flux produced by the winding. The core is made up of high-grade silicon steel laminations.
02. Limb – The function of the limb is to carry windings or coil. The vertical position of core in the transformer is called a limb.
03. Yoke – The horizontal position of the core is called a yoke. The function of a yoke is to carry flux produced by one winding to another winding.
04. Windings – The function of the winding is to carry current and to produce flux. The coil which is used on a limb is properly insulated from each other.
05. Conservator – During operation of the transformer sometimes heat will be produced inside the transformer which increases the temperature inside of the transformer, the function of a conservator is to take the expansion of oil without allowing it to come in contact with ambient air.
06. Breather – While the transformer taking air inside or leaving out the breather will extract the moisture which is present in the air. When air is taken in before that breather extract moisture from the air, the breather does not allow transformer oil to come in contact with moisture.
07. Explosion Vent – The vent is fixed on the main tank when the pressure inside the tank increases then the pressure will come out through vent and thus protect the transformer.
08. Buchholz Relay – The Buchholz relay is the protective device in a transformer when the fault is developed and gases are released in the transformer, Buchholz relay operates based on these gases and initiates the operation of the circuit breaker.
Insulating Material Used In A Transformer
- 01. Glass tape, cotton or paper are materials used to cover conductors.
- 02. Varnished cloth or bakelite paper cylinders are material used to insulate low voltage winding from the core and also between windings.
- 03. For the oil-immersed transformer, oil acts as insulating material.
Properties Of Transformer Oil
- 01. High dielectric strength
- 02. High thermal conductivity
- 03. Low viscosity
- 04. High resistivity
- 05. Low specific gravity
- 06. Low power factor
Function Of Transformer Oil
- 01. The oil transfers heat produced to the surroundings and keep the transformer cool
- 02. It also acts as an insulating medium
