Tata Steel Downstream Products Mechanical Maintenance Engineer Trainee Interview Questions and Answers

MCC stands for Motor Control Center and PCC stands for Power Control Center. They are electrical panels used to control and distribute power to motors and other electrical equipment.

• MCC panels are used to control and distribute power to motors in industrial settings.

• PCC panels are used to control and distribute power to various electrical equipment.

• Both panels play a crucial role in ensuring efficient and safe operatio...read more

An induction motor is a type of AC motor where power is supplied to the rotor by electromagnetic induction.

• Induction motors are commonly used in various applications such as industrial machinery, pumps, fans, and compressors.

• They do not require brushes to transfer power to the rotor, making them more reliable and maintenance-free compared to brushed DC motors.

• The speed of an induction motor is determined by the frequen...read more

A DC series motor is a type of DC motor where the field winding is connected in series with the armature winding.

• Field winding and armature winding are connected in series

• High starting torque but low speed

• Used in applications where high starting torque is required, such as in traction applications

Power factor is the ratio of real power to apparent power in an AC circuit. VFD stands for Variable Frequency Drive. AC motors run on alternating current while DC motors run on direct current.

• Power factor is a measure of how effectively electrical power is being used in a circuit.

• It is calculated by dividing the real power (in watts) by the apparent power (in volt-amperes).

• A power factor of 1 indicates that all the pow...read more

Types of load cells include strain gauge load cells, hydraulic load cells, and capacitive load cells.

• Strain gauge load cells measure the strain or deformation of a material.

• Hydraulic load cells use hydraulic fluid to measure force.

• Capacitive load cells measure changes in capacitance to determine force.

• Other types of load cells include piezoelectric load cells and pneumatic load cells.
