CHAPTER 3 : THE PRINCIPLE OF TRANSFORMER

In this article, I want to share you about transformer! what is transformer?

Transformer is a static device used to transfer energy from one to another circuit without any direct electrical connection and with the help of mutual induction between two windings. It transforms power from one circuit to another without changing its frequency but may be in different voltage level. There are two kind of transformer :

1. step up transformer 

2. step down transformer

The differences between step-up and step down transformer is depend on the transfer energy of the voltage. When the transformation take place with an increase in voltage it's called step up transformer but if the voltage is decreased, it's called a step down transformer.

The figure above shows the part of transformer, there are primary and secondary winding or coils, and also primary coils. Primary winding used to the power from supply and from primary come to secondary winding which is used to delivers the power to the load.

So, How the transformer works?

The principle of transformer is depends on Faraday's Law about electromagnetic induction. mutual induction is one of principle of transformer. mutual induction occurs when the magnetic field surrounding one conductor cuts across another conductor inducing a voltage in it.
