Transformer Types - Types of Transformer - Electrical Transformers Types

There are many types of transformers used in the power supply system for different purposes such as the generation, distribution, transmission and use of electric power.

 The different types of transformers are: step-up transformer and step-up transformer, power transformer, distribution transformer, instrument transformer including current and potential transformer, single-phase and three-phase transformer, automatic transformer, etc.


This type of transformer is classified on the basis of the number of turns in the primary and secondary windings and the induced electromotive force.

Step-up transformer transforms a low voltage, high alternating current into a high voltage and low current alternating system In this type of transformer, the number of turns in the secondary winding is greater than the number of turns in the primary winding. If (V2> V1) the voltage is increased on the output side and is called step-up transformer

Step-down transformer converts a primary high voltage associated with low current into a low voltage, high current. With this type of transformer, the number of turns in the primary winding is greater than the number of turns in the secondary winding. If (V2 <V1) the voltage level is lowered on the output side and is called a step-down transformer


Power transformer
Power transformers are used in higher voltage transmission networks. The nominal characteristics of the power transformer are as follows: 400 KV, 200 KV, 110 KV, 66 KV and 33 KV. They are mainly rated above 200 MVA. Mainly installed in power plants and transmission substations. They are designed for maximum efficiency of 100%. They are larger in size than a distribution transformer.
