JSW Steel Shift Engineer Interview Questions and Answers

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.

The capacity of a furnace refers to its heating output, typically measured in BTUs or tons.

• Furnace capacity is determined by the amount of heat it can produce.

• It is usually measured in BTUs (British Thermal Units) or tons.

• Higher capacity furnaces can produce more heat and are suitable for larger spaces.

• For example, a furnace with a capacity of 80,000 BTUs can heat a larger area compared to one with a capacity of 40,000

Drive components in CCM department are the parts that enable the motor to function properly.

• Drive components include motors, gears, belts, and pulleys.

• They work together to transfer power from the motor to the machine.

• The components must be properly sized and aligned to ensure efficient operation.

• Examples of machines that use drive components include conveyor belts, pumps, and fans.
