Meghalaya Cements Interview Questions, Process, and Tips

Process control is the use of technology to monitor and control industrial processes.

• Process control involves measuring variables such as temperature, pressure, and flow rate.

• Control systems use this data to adjust process parameters and maintain optimal conditions.

• Examples include controlling the temperature in a chemical reactor or the flow rate of water in a pipeline.

• Process control is essential for ensuring product...read more

A slipring induction motor is a type of AC motor that uses slip rings to transfer power to the rotor.

• Consists of a stator and a rotor

• Uses slip rings to transfer power to the rotor

• Commonly used in applications where variable speed is required

• Examples include cranes, elevators, and conveyor systems

Corona effect is the ionization of air surrounding a conductor due to high voltage gradient.

• Occurs in high voltage transmission lines

• Leads to power loss and radio interference

• Can be reduced by increasing conductor diameter or using bundled conductors

• Can also be reduced by using corona rings or grading rings

• Can be dangerous for people and animals in close proximity

Dol starter is an electrical device used to start and stop motors.

• Dol stands for Direct-On-Line.

• It is used for motors with low to medium power ratings.

• It consists of a contactor, overload relay, and start and stop push buttons.

• When the start button is pressed, the contactor closes and the motor starts.

• When the stop button is pressed, the contactor opens and the motor stops.
