The transformer is a common word for an electrical engineer and engineering student. In this post, I will discuss what is a transformer, its working principle, transformer construction, types of the transformer and transformer testing. I am going to post a series of articles about the transformer with video. So let’s go.
By one sentence we can say, a transformer is a static piece of electrical equipment that can transform AC electric power from one circuit to another by step-up or by step-down the main voltage with the same frequency. It is one of the most common electrical equipment with a different size than we are using in our daily life form morning to night.
A transformer has two or more separate coil windings placed on a common magnetic core. But the primary coil winding is responsible for supplying the alternating current (AC) with supplied frequency and it produces the magnetic flux in the same frequency in the magnetic core.
Then the flux linkage to the secondary coil winding also changes at the same frequency resulting in induced e.m.f of the same frequency to the secondary coil winding. But the direction of induced e.m.f in the secondary coil winding opposes the causes of producing the alternating flux by the primary coil winding.

The transformer has several applications for use. So transformer design, types, and accessories are depended upon its size, application, and location. Now there are some components and accessories of a transformer,
A power transformer has several types like two winding transformers, three winding transformers, and the autotransformer. Besides the autotransformer and the power transformer, there are great verities of a special transformer. It includes the following,
