SHYAM METALICS AND ENERGY Assistant Engineer Interview Questions and Answers

Q1. What is the theory behind the transformer’s operation principle?
Ans. 
A transformer operates on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.
• Transformers consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of ferromagnetic material.

• When an alternating current flows through the primary coil, it creates a changing magnetic field in the core.

• This changing magnetic field induces a voltage ...read more

Q2. How and why is a transformer’s rated capacity expressed?
Ans. 
A transformer's rated capacity is expressed in terms of its maximum power output, typically in kilovolt-amperes (kVA).
• Rated capacity is expressed in kVA to indicate the maximum power output the transformer can handle.

• This rating helps determine the appropriate size of transformer needed for a specific application.

• For example, a transformer with a rated capacity of 500 kVA can handle a maximum power output of 500 kilovo...read more
