10+ Assistant Engineering Manager Interview Questions and Answers

To check if a lightning arrestor is working fine, you can perform visual inspections, check for physical damage, test for continuity, and monitor surge protection levels.

• Perform visual inspections for any signs of physical damage or wear

• Check for loose connections or corrosion on the lightning arrestor

• Test for continuity using a multimeter to ensure proper electrical connection

• Monitor surge protection levels to ensure the lightning arrestor is diverting excess voltage

• Consider...read more

The tertiary winding in a power transformer is important for providing a path for zero-sequence currents and reducing harmonics.

• Provides a path for zero-sequence currents, which helps in balancing the three-phase system

• Reduces harmonics in the system, improving power quality

• Helps in limiting fault currents and improving the overall efficiency of the transformer

Selection of a cable involves considering factors like voltage rating, current carrying capacity, insulation material, and environmental conditions.

• Determine the voltage rating required for the application.

• Calculate the current carrying capacity needed based on the load.

• Select the appropriate size and type of cable based on the current rating.

• Consider the insulation material suitable for the environment (e.g. PVC, XLPE).

• Take into account any special requirements such as flexi...read more

The engineer started with education and training in engineering principles and practices. Turbines and propellers work by converting fluid or air pressure into rotational motion.

• Engineers typically start with a degree in engineering or a related field, followed by on-the-job training and experience.

• Turbines work by using the pressure of a fluid, such as steam or water, to turn a rotor and generate electricity. The rotor is connected to a shaft that drives a generator.

• Propelle...read more

Load factor is the ratio of the average load to the maximum load that a system can handle.

• Load factor is calculated by dividing the average load by the maximum load capacity.

• It is used to measure the efficiency of a system or equipment in handling varying loads.

• For example, a power plant with a load factor of 0.8 means it is operating at 80% of its maximum capacity.

DG stands for Diesel Generator. It is a backup power source used in case of power outages.

• DG is a combination of a diesel engine and an electric generator.

• The diesel engine drives the generator to produce electricity.

• DGs are commonly used in industries, hospitals, and residential buildings.

• They are also used as a backup power source for critical facilities like data centers.

• DGs require regular maintenance to ensure their proper functioning.

Relay is an electrical switch that uses an electromagnet to open or close a circuit.

• Relays are used to control high voltage or current circuits with low voltage signals.

• They work by using an electromagnet to move a switch, which opens or closes the circuit.

• Relays can be used for a variety of applications, such as controlling lights, motors, and solenoids.

• They are also used in safety systems, such as emergency stop buttons.

• Relays come in different types, such as electromagneti...read more

The plane's capacity is determined by its size, weight, and design.

• The size of the plane determines how many passengers and cargo it can carry.

• The weight of the plane affects its fuel efficiency and range.

• The design of the plane can also impact its capacity, such as the number of seats or cargo hold space.

• For example, a Boeing 747 has a capacity of around 660 passengers, while a smaller regional jet may only hold around 50 passengers.

CSV stands for Comma-Separated Values, a file format used to store tabular data in plain text.

• CSV files contain data separated by commas or other delimiters

• Each line in a CSV file represents a row in the table

• CSV files can be easily imported and exported in spreadsheet software like Excel
