What is transformer and Applications of transformer

Do you know the applications of transformers? Regarding we can see as following in this article. A device used to reduce or increase the current flowing through an electrical device; a Power converter/transformer. Transformers will use in various industries. It includes power generation, transmission, distribution of power supplies, lighting, audio systems, yet and electronic equipment Etc. Furthermore, in the Current generation, each apartment also will use an individual transformer as a power supply. Why, Because power needs there in that much of so.

How to work in a transformer?

A transformer is a use to increase or decrease the voltages. Furthermore, reduce or increase in current. Thus, the working principle of the transformers on Faraday’s law in electromagnetic induction and mutual induction. In this case, the transformers have two coils commonly. That coils are the primary coil and secondary coil – on the transformer core.

Different types of transformers:

  • Autotransformer.
  • Industrial control transformer.
  • Isolation transformer.
  • Medium voltage control transformer.
  • Power transformer.
  • Step-up transformer.
  • Step-down transformer.
  • Distribution transformer
  • Single phase transformer
  • Dry type transformer
  • Pulse transformer
  • Grounding transformer
  • Audio transformer
  • Iron core transformer
  • Air core transformer
  • Instrument transformer
  • Power transformer
  • Core type transformer
  • Shell type transformer
  • Three phase transformer
  • Ferrite core transformer
  • Toroidal core transformer

On the whole, these are all types of transformers there in industries. Each of the transformers will use individual processing places. A current generation without a transformer can’t run the world. So furthermore, the transformers wherever will use in deep detail can see below.

Applications of transformer:

  • Power generation
  • Transmission and distribution
  • Lighting
  • Audio systems
  • Electronic equipment

Power generation:

Transformers are used in power plants to increase the voltage of the electricity generated by the plant before it is sent to the grid.

Transmission and distribution:

The transformers are used in the transmission and distribution of electricity to increase or decrease the voltage of electricity as it is sent from power plants to homes and business places.


Transformers are used in lighting systems to decrease the voltage of electricity before it is sent to light bulbs.

Audio systems:

The transformer is used in audio systems to increase or decrease the voltage of electricity before it is sent to speakers.

Electronic equipment:

The transformer is used in various electronic equipment also. In addition, computers, TVs, radios, and cell phones.

Benefits of the transformer:

  • Efficiency
  • Safety
  • Reliability


It can transfer electricity more than efficiently and other methods, such as power supplies. However, which means that less energy is lost in the form of heat, then later results in lower energy costs.


In addition, the transformer is more safer than other methods of electrical power distribution. Why? because they do not rely on high-voltage power lines, which can pose a serious electrocution hazard.


On the whole, transformers are more reliable and have a long lifetime. They can differently last for decades with proper maintenance.

In conclusion:

Hence, In this article via the definition of transformer, how it works, transformer applications, and benefits are all detail known clearly.
