Kirloskar Ferrous Industries Interview Questions and Answers

Boiler troubleshooting involves identifying and resolving issues to ensure efficient operation and safety.

• Check water levels: Low water levels can cause overheating and damage.

• Inspect pressure gauges: Abnormal pressure readings may indicate a malfunction.

• Examine safety valves: Ensure they are functioning to prevent overpressure.

• Look for leaks: Leaks can lead to loss of efficiency and safety hazards.

• Monitor tempera...read more

DOL and Star-Delta starters are methods to control the starting of three-phase induction motors.

• DOL (Direct On Line) starter connects the motor directly to the power supply.

• Star-Delta starter reduces the starting current by initially connecting the motor in star configuration.

• DOL is simple and cost-effective but can cause high starting current.

• Star-Delta is more complex but reduces starting current and torque, sui...read more

Different types of protection are used in a substation to ensure safety and reliability.

• Overcurrent protection: Protects against excessive current flow.

• Overvoltage protection: Safeguards against high voltage surges.

• Differential protection: Detects faults by comparing currents entering and leaving the substation.

• Distance protection: Protects transmission lines based on the distance to the fault.

• Ground fault protect...read more

Different types of HT breakers are used in HT lines depending on the specific requirements.

• Air Circuit Breaker (ACB) is commonly used in HT lines for its high breaking capacity and quick response time.

• Vacuum Circuit Breaker (VCB) is another popular choice due to its compact size and low maintenance requirements.

• SF6 Circuit Breaker is used for high voltage applications as it provides excellent arc quenching propert...read more

A circuit diagram of hydraulics shows the flow of hydraulic fluid through a system of valves, cylinders, and pipes.

• Hydraulic pump: generates pressure to move fluid through the system

• Valves: control the direction and flow rate of the fluid

• Cylinders: convert fluid pressure into mechanical force

• Pipes: transport the fluid between components

• Pressure gauges: monitor the pressure levels in the system

The specific power consumption of a plant depends on various factors such as the type of plant, its size, and the equipment used.

• Specific power consumption is the amount of energy consumed per unit of production.

• It can be calculated by dividing the total energy consumption by the total production output.

• Factors that affect specific power consumption include the type of plant, its size, the equipment used, and the ...read more
