What is Transformer?
A transformer is a device that transfers electric power from one alternating-current circuit to another circuit without a change in frequency.
Working Principle
It works on the principle of Faraday’s Law of Electromagnetic Induction which states that “ the magnitude of voltage is directly proportional to the rate of change of flux.”
Construction of a Transformer
It mainly consists of
- Magnetic circuit (consisting of core, limbs, yoke and damping structure).
- Electrical circuit (consisting of primary and secondary windings)
- Dielectric circuit (consisting of insulations in different forms and used at different places)
- Tanks and accessories (conservator, breather, bushings, cooling tubes, etc.)
