ArcelorMittal Nippon Steel Interview Questions, Process, and Tips for Freshers

Q1. Which conductor use in transmission line
Ans. 
Transmission lines typically use aluminum or copper conductors for efficient electricity transfer over long distances.
• Aluminum conductors are lightweight and have good conductivity, making them ideal for overhead transmission lines.

• Copper conductors offer higher conductivity than aluminum but are heavier and more expensive.

• ACSR (Aluminum Conductor Steel Reinforced) combines aluminum and steel for strength and conductiv...read more

Q2. Motor working principle
Ans. 
Electric motors convert electrical energy into mechanical energy using electromagnetic principles.
• Motors operate on the principle of electromagnetism, where a magnetic field interacts with current-carrying conductors.

• The basic components include a stator (stationary part) and a rotor (rotating part).

• In AC motors, alternating current creates a rotating magnetic field that induces motion in the rotor.

• In DC motors, direct...read more

Q3. Types of winding in motor
Ans. 
Motors utilize various winding types, including stator and rotor windings, to create magnetic fields for operation.
• Stator Windings: Fixed windings that create a rotating magnetic field.

• Rotor Windings: Located on the rotor, can be squirrel cage or wound type.

• Lap Winding: Used in DC machines for low voltage and high current applications.

• Wave Winding: Suitable for high voltage and low current applications.

• Field Windings: ...read more

Q4. Transformers working principle
Ans. 
Transformers operate on electromagnetic induction to transfer electrical energy between circuits at different voltage levels.
• Transformers consist of two coils: primary and secondary.

• They work on the principle of Faraday's law of electromagnetic induction.

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

• This magnetic field induces a voltage in the secondary coil.

• Transformers can step ...read more
