Bajaj Hindustan Sugar Mill Maintenance Electrician Interview Questions and Answers

The environment in your organisation is professional, collaborative, and supportive.

• Professionalism is evident in the way employees conduct themselves and handle tasks.

• Collaboration is encouraged among team members to achieve common goals.

• Supportive atmosphere where employees feel valued and motivated to excel.

• Open communication channels foster a positive work environment.

Current value refers to the amount of electric current flowing through a circuit at a specific point in time.

• Current value is measured in amperes (A)

• It indicates the rate of flow of electric charge

• Higher current values can indicate potential hazards such as overloading

• Current value can be calculated using Ohm's Law: I = V/R, where I is the current, V is the voltage, and R is the resistance

Transformers play a crucial role in ensuring safety in electrical systems.

• Transformers help in isolating electrical circuits, preventing electric shocks.

• They provide voltage regulation, preventing overvoltage or undervoltage conditions.

• Transformers can be equipped with protective devices like fuses or circuit breakers.

• Regular maintenance and inspections are necessary to ensure transformer safety.

• Proper grounding of tra...read more

DG PMS stands for Diesel Generator Power Management System. Delay work refers to the delay in the functioning of the system.

• DG PMS is a system used to manage and control the power supply from diesel generators.

• Delay work in DG PMS refers to any delay or interruption in the normal functioning of the system.

• Examples of delay work in DG PMS can include issues with the generator starting, fuel supply problems, or malfuncti...read more

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

• Power factor is the ratio of real power (in watts) to apparent power (in volt-amperes).

• It indicates the efficiency of electrical equipment in converting electrical power into useful work.

• A power factor of 1 means all the power is being used effectively, while a power factor less than 1 indicates wastage of power.

• Inductive loads lik...read more

There are mainly two types of motors - AC motors and DC motors.

• AC motors: Induction motors, synchronous motors

• DC motors: Brushed DC motors, brushless DC motors

• Other types: Servo motors, stepper motors

VFD stands for Variable Frequency Drive. It is used to control the speed and torque of an electric motor by varying the frequency and voltage of the power supplied to it.

• Controls the speed and torque of an electric motor

• Varies the frequency and voltage of the power supplied to the motor

• Helps in energy savings by adjusting motor speed based on load requirements

• Used in various applications like pumps, fans, conveyors, an

MPCB stands for Motor Protection Circuit Breaker. It is used to protect motors from overloads, short circuits, and phase failures.

• Protects motors from overloads by tripping the circuit when current exceeds a set limit

• Protects motors from short circuits by quickly disconnecting power

• Protects motors from phase failures by detecting imbalance in current flow

• Helps in preventing damage to the motor and associated equipment

• C...read more
