1.1 Transformer Working Principle
How Transformers Transfer Power Efficiently
Why Am I Writing This Blog (you can skip this)?
This blog is an extension of my personal portfolio, where I showcase my education, technical skills, and completed projects. While most of my portfolio highlights web development–related work, this space allows me to document and share my academic learning in Electrical Technology.
Through this blog, I aim to organize my study notes, reinforce my understanding of core electrical concepts, and create a knowledge base that may also benefit other students at a similar learning stage. It reflects my commitment to continuous learning and demonstrates how I integrate theoretical knowledge with practical and technical growth.
Working Principle of Transformer:
Basically Transformer is a Static piece of apparatus by mean which electric power in one circuit transferred to another circuit with the same frequencey. It can rise and lower the voltage but in corresponding it decreases or increases the current.
Formations of Transformer:
It consist of two inductive coils which are electrically seperated but magnetically they are linked through low reluctance path (laminated core) as show in figure.
Here:
If one coil connected to source of Alternating Voltage, An Alternating Flux is set up in the laminated core, most of which is linked with the other coil in which it produces mutually induced emf ( according to Faraday’s Law of Electromagnetic Induction e=MdI/dt ).
If second coil circuit is closed, a current flows in it and so electric energy is transferred (entirely magnetically) from the first coil to second coil.
The first coil, in which electric energy is fed from the AC supply main, is called primary winding.
The other which energy drawn out, is called Secondary Winding.
Conculsion:
Transformer is a device that:
Transfer electric power from one ciruit to another.
It does so without changing a freqency.
It accomplishes this by electromagnetic induction.
Where the Two Electric Circuits are in mutual inductive influence of each other.
