10+ Engineering Supervisor Interview Questions and Answers

Breathers are used in current transformers to prevent moisture and dust from entering the transformer.

• Breathers are devices that allow air to enter and exit the transformer, while preventing the entry of moisture and dust.

• They are typically filled with a desiccant material, such as silica gel, which absorbs moisture from the air.

• The desiccant material changes color when it becomes saturated, indicating that it needs to be replaced.

• The color of the breather can vary depending ...read more

Sensors are devices that detect and respond to input from the physical environment, such as temperature, pressure, gas, and flow.

• Sensors are used to measure physical quantities and convert them into signals that can be read and interpreted by electronic devices.

• Examples of sensors include temperature sensors, which measure the temperature of a system or environment, pressure sensors, which measure the pressure of a gas or liquid, gas sensors, which detect the presence of spec...read more

Quality assurance is the process of ensuring that products or services meet specified requirements and standards.

• Quality assurance involves creating a plan to monitor and evaluate the quality of products or services.

• It includes setting quality standards, conducting inspections and tests, and implementing corrective actions when necessary.

• Quality assurance also involves continuous improvement to enhance the overall quality of products or services.

• Examples of quality assurance ...read more

I follow strict safety protocols to ensure the well-being of my team and prevent accidents.

• I always conduct regular safety inspections to identify and address any potential hazards.

• I ensure that all team members are properly trained in safety procedures and use of protective equipment.

• I enforce strict adherence to safety guidelines and regulations at all times.

• I prioritize communication and encourage team members to report any safety concerns or incidents immediately.

PM maintenance stands for Preventive Maintenance, which involves regularly scheduled maintenance tasks to prevent equipment breakdowns.

• PM maintenance involves performing routine maintenance tasks on equipment to prevent unexpected breakdowns.

• It includes tasks such as inspections, lubrication, adjustments, cleaning, and parts replacement.

• PM maintenance helps extend the lifespan of equipment and reduce overall maintenance costs.

• Examples of PM maintenance tasks include changing ...read more

Degree of freedom refers to the number of independent variables or parameters that can be varied in a system.

• Degree of freedom is the number of variables that can be changed independently without affecting the overall system.

• In engineering, degree of freedom can refer to the number of axes along which a mechanical system can move.

• For example, a rigid body in space has 6 degrees of freedom - 3 translational and 3 rotational.

• In control systems, degree of freedom can refer to th...read more

A DG (diesel generator) works by converting diesel fuel into mechanical energy through combustion, which is then converted into electrical energy through an alternator.

• Diesel fuel is injected into the combustion chamber where it is ignited by a spark plug or compression, creating controlled explosions that drive the pistons.

• The pistons turn the crankshaft, which is connected to the alternator, causing it to rotate and generate electricity.

• The electricity produced is then tran...read more

DC's are direct current power sources while PLCs are programmable logic controllers used for automation.

• DC's provide constant voltage and current flow in one direction, used in simple circuits.

• PLCs are digital computers used to control machinery and processes, programmed using ladder logic or other languages.

• DC's are typically used for power supply in electronic devices, while PLCs are used for automation in industrial settings.

• DC's are simpler and more basic compared to the ...read more

TPM stands for Total Productive Maintenance, a proactive approach to maintenance that aims to maximize equipment effectiveness.

• TPM focuses on preventing equipment breakdowns through regular maintenance and employee involvement.

• It involves setting up autonomous maintenance teams to perform routine tasks and inspections.

• TPM also includes planned maintenance, quality maintenance, and focused improvement activities.

• Example: Implementing TPM in a manufacturing plant to reduce down...read more

UPS stands for Uninterruptible Power Supply, which provides backup power in case of electrical failure.

• UPS works by converting AC power to DC power and storing it in batteries.

• During a power outage, the UPS switches to battery power to provide continuous electricity to connected devices.

• UPS systems come in different sizes and capacities to support various loads and runtime requirements.

• Some UPS units also offer surge protection and voltage regulation to protect connected equi...read more
