ITC Industrial Engineer Trainee Interview Questions, Process, and Tips

The motor makes noise due to various reasons such as mechanical issues, electrical problems, or worn-out components.

• Mechanical issues like loose parts or misalignment can cause noise in the motor.

• Electrical problems like faulty wiring or improper grounding can also contribute to motor noise.

• Worn-out components such as bearings or brushes can generate noise during operation.

• Excessive load or overloading the motor can le...read more

The main types of electrical current are AC and DC.

• AC (alternating current) changes direction periodically and is used in most household appliances.

• DC (direct current) flows in one direction and is used in batteries and electronic devices.

• Other types of current include pulsed DC and sinusoidal AC.

• AC and DC can be converted into each other using devices like transformers and rectifiers.

Cables used in power transmission are typically high-voltage power cables made of copper or aluminum.

• High-voltage power cables are used for long-distance transmission of electricity.

• Copper and aluminum are the most commonly used materials for power cables.

• Cables may be insulated with materials such as rubber, plastic, or oil.

• Examples of power cables include overhead transmission lines, underground cables, and submarine

Transformers work on the principle of electromagnetic induction to transfer electrical energy from one circuit to another.

• Transformers have two coils of wire, a primary coil and a secondary coil, wrapped around a magnetic core.

• When an alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.

• The voltage induced in the secondary coil is proportional to t...read more

Silicagel is used in transformers to absorb moisture and prevent damage to the insulation.

• Silicagel is a desiccant that absorbs moisture from the air.

• Moisture can cause damage to the insulation in transformers.

• Silicagel helps to prevent this damage by absorbing moisture.

• It is important to keep transformers dry to ensure their proper functioning.

• Silicagel is also used in other electrical equipment, such as circuit break
