What Are Electrical Transformers and Their Types?

  • 02 Mar, 2020

A transformer is an electrical device that is used to transfer electrical energy from one electrical circuit to another without frequency fluctuation. It works on the principle of electromagnetic induction to step up (increase) or step down (decrease) the voltage levels between circuits. They are also sometimes known as electrical energy transformers. Transformers are widely used in power stations and transmission sub-stations.

Transformers are very important and useful in the electrical power system as they are used to transfer AC supply from the power sub-station to our home. They are used to reduce the energy loss by transforming the voltage to a much higher level on power transmission cables over very long distances. Higher voltage value implies to the lower currents for the same power and therefore lower I2*R losses through transmission lines. And after that, a step-down transformer reduces these higher AC transmission voltages and currents to a much lower voltage level to supply them to homes and workplaces for safe use.

Uses of Electrical transformers

  • Raising or lowering the voltage level in AC transmission systems
  • Used to prevent the DC supply transmission through the circuit
  • Used to isolate two electric circuits
  • Used to step up the voltage level at a power transmission system before the transmission and distribution through power grids
  • Used to step down the AC supply at much lower, safer and usable voltage level at substations before distributing to residential and commercial places.

Electrical energy transformers are very important equipment in a power transmission system that is used to transfer AC supply from the power station to our homes. If you are looking to purchase transformers for your industrial use, you should be aware of the different kinds of electrical transformers and their uses. Transformers are classified in different categories based on many factors. The main types are as follow:

  • Based on design and construction transformers are classified into core type transformer and shell-type transformers.
  • Based on the supply transmission transformers are classified into single-phase transformer and three-phase transformer. 3-phase transformers are mainly used for the generation, transmission, and distribution in power transmission and distribution systems.
  • Based on the purpose transformers are classified as a step-up transformer and step-down transformer. Both are used for the exact opposite functionality for different purposes.
  • Based on use, transformers are classified into power transformer, distribution transformer, and instrument transformer. Instrument transformer is further classified as a current transformer and potential transformer.
  • Based on cooling systems, transformers are classified as a self-cooled transformer, water-cooled transformer, and air-cooled transformer.
