Essel Mining & Industries Deputy Manager Interview Questions and Answers

GTG operation involves multiple generators working together to share the load and ensure continuous power supply.

• GTG stands for Gas Turbine Generator

• In GTG operation, multiple generators are synchronized to work together

• Load sharing ensures that the power demand is distributed evenly among the generators

• This helps in maintaining a stable power supply and prevents overloading of any single generator

Calculate rope diameter based on overhead crane capacity

• Calculate the weight of the load the crane will be lifting

• Determine the maximum load capacity of the crane

• Use the formula: Rope diameter = (Load weight / (2 * Safe working load * Safety factor * π))^0.5

• For example, if the load weight is 10 tons, safe working load is 5 tons, and safety factor is 2, the rope diameter would be calculated as: (10000 / (2 * 5 * 2 * 3.1

Centrifugal pump efficiency curves show the relationship between flow rate and efficiency of the pump.

• Efficiency curves help in selecting the right pump for a specific application

• They provide information on the pump's performance at different operating points

• Efficiency curves typically have a peak efficiency point and a best efficiency point (BEP)

• Understanding these curves can help in optimizing pump performance and en

The cost of solenoid valves and servos can vary depending on the brand, size, and quality.

• Cost of solenoid valves can range from $10 to $1000+ depending on size and brand.

• Servos can cost anywhere from $20 to $500+ depending on torque and brand.

• Higher quality solenoid valves and servos may have a higher price tag.

• Consider factors like durability, performance, and warranty when comparing costs.

Safety norms and company acts are regulations and guidelines put in place to ensure the safety and well-being of employees in the workplace.

• Safety norms include wearing personal protective equipment (PPE) such as helmets, gloves, and safety shoes.

• Company acts may include regular safety training sessions for employees to educate them on potential hazards and how to prevent accidents.

• Safety norms also cover emergency pro...read more

Power station design involves the planning and construction of facilities that generate electricity.

• Design includes selection of appropriate technology and equipment

• Consideration of environmental impact and safety measures

• Layout and construction of buildings and infrastructure

• Integration with power grid and transmission systems

• Examples include thermal power plants, hydroelectric power plants, and wind farms

Efficiency of a power station is the ratio of output power to input power.

• Efficiency can be improved by using advanced technologies and equipment.

• Regular maintenance and cleaning of equipment can also improve efficiency.

• Efficiency can be affected by factors such as fuel quality, weather conditions, and demand for electricity.

• For example, a power station using combined cycle technology can achieve an efficiency of up to...read more
