Oriental English Medium School Interview Questions and Answers

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 protection: Detects faults to ground and prevents electrical shock haz...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 properties.

• Oil Circuit Breaker (OCB) was commonly used in the past but...read more

The speed of a machine directly impacts its efficiency, as a faster machine can typically produce more output in a given amount of time.

• Higher machine speed can lead to increased productivity and output

• However, higher speed may also result in more wear and tear on the machine, leading to maintenance issues

• Efficiency can be improved by optimizing machine speed based on the specific task and production requirements

Yes, the vibration level of a vibration motor can be changed.

• The vibration level can be adjusted by changing the voltage or frequency of the power supply.

• The weight of the motor's eccentric mass can also be adjusted to change the vibration level.

• Different types of vibration motors have different methods for adjusting the vibration level.

• It is important to ensure that any changes made to the vibration level do not cause damage to the motor or the equipment it is used in.

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

• Depth of knowledge and skills in the specific field

• Ability to handle complex tasks and projects with ease

• Experience in dealing with challenging situations and finding solutions

• Strong understanding of industry trends and best practices

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 production process.

• Efficient equipment and processes can help r...read more
