Types of transformer

A variety of types of electrical transformer are made for different purposes. This article discusses different types of transformers and their applications. The different types of transformer are Step up and Step down transformer, Power and Distribution transformer, Instrument transformer, current and Potential transformer, Single phase and Three phase transformer. Information on transformers and transformer components including different types of transformers and their applications.

Transformer operates on an ac supply.

However, this type of transformer construction were the two windings are wound on separate limbs is not very .

The transformers are classified as step-up and step-down transformers as the voltage ratios from primary to secondary.

These are widely used transformer types for all the applications. Here the important thing to remember is that there will not be any difference in primary power and secondary power. The most common types of transformers found in electrical transmission systems, industries and electronic applications include power transformers, instrument transformers, tap changing transformers, auto transformers, RF transformer, audio transformers, etc. They all are different in size, ratings and shape . Most of the electronic circuits used in Circuitstoday. Therefore, it is important to know the working principle, construction and types of transformers used in different analog circuits.

The following six types of transformers are normally used in commercial buildings - substation primary-unit and secondary-unit, network, pad-mounted. Here, you will get all types of most . In this type of transformers windings . Are you aware of theses types of testing an electrical transformers should have? Electrical transformers should be tested prior to arrival on site. There are several different types of transformers available in the world market, mainly divided by Power and tension supplie but also depending on its application.

Here we list the major differences trying to explain in general their advantages and applications. Help us to add one more member (video editing expert) to the team. Different types of transformer core assemblies are illustrated in this video with help of animation. The core and shell type of constructions are explained for . The winding types explained are disc-type, . Cast resin dry type transformer (CRT) is used in the high moisture prone areas. It is because of its primary and secondary windings are encapsulated with epoxy resin.

This encapsulation helps to prevent moisture to penetrate to affect the winding material. Complete protection is achieved by this cast resin encapsulation so . For confirming the specifications and performances of an electrical power transformer it has to go through numbers of testing procedures. Some tests are done at manufacturer premises before delivering the transformer.

Mainly two types of transformer testing are done at manufacturer premises- type test of transformer and . Although they all share the basic characteristic transformer principles, they are customized in construction or electrical properties for certain installation requirements or circuit conditions. Then, Star-Star would be labelled Yy, Delta-Delta . Scientist Faraday designed few laws which can be explicitly applied to transformers to efficiently change AC .
