Amptitude test average
Generation, transmission, and distribution system are the three main components of the electricity supply chain.
Generation: Production of electricity from various sources like coal, natural gas, hydro, wind, solar, etc.
Transmission: High voltage lines used to transport electricity over long distances from power plants to substations.
Distribution: Low voltage lines that deliver electricity from substations to homes, bus
Transmission is in high voltage to reduce energy losses and increase efficiency.
High voltage reduces energy losses during transmission
Lower current at higher voltage leads to lower resistive losses
Efficiency of transmission lines increases with higher voltage
High voltage allows for long distance power transmission with minimal losses
Generators and motors work on the principle of electromagnetic induction.
Generators convert mechanical energy into electrical energy through electromagnetic induction
Motors convert electrical energy into mechanical energy through electromagnetic induction
Both devices rely on the interaction between magnetic fields and conductors to function effectively

I applied via Walk-in and was interviewed before Oct 2020. There were 3 interview rounds.
PSL 2 has stricter requirements than PSL 1. Gas pipelines use PSL 2 pipes.
PSL 2 has higher minimum yield strength and stricter chemical composition requirements than PSL 1
PSL 2 also has non-destructive inspection requirements
Gas pipelines use PSL 2 pipes due to their higher strength and durability
PSL 1 pipes are typically used for low-pressure applications
I applied via Company Website and was interviewed in Apr 2023. There were 3 interview rounds.
UT stands for Ultrasonic Testing, a non-destructive testing method used in engineering.
UT uses high frequency sound waves to detect flaws or defects in materials.
It is commonly used in industries like aerospace, automotive, and manufacturing.
UT can be used to inspect welds, pipelines, and structural components.
The results of UT are displayed in a visual representation called a C-scan or B-scan.
I applied via Campus Placement and was interviewed before Apr 2022. There were 4 interview rounds.

A tray functions in a column by providing a surface for the separation of different components in a process.
Trays are used in distillation columns to separate different components based on their boiling points.
They provide a large surface area for vapor-liquid contact, allowing for efficient separation.
Trays can have various designs, such as bubble cap trays or sieve trays, to enhance separation efficiency.
They can als...

Conveyors are used in materials handling to efficiently transport goods or materials from one place to another.
Conveyors help in automating the transportation process, increasing efficiency and reducing manual labor.
They can handle a wide range of materials, from small parts to heavy items.
Conveyors can be customized to fit specific needs, such as incline or decline conveyors for elevation changes.
Examples of conveyors...
Preventive maintenance is the practice of regularly inspecting, servicing, and replacing parts to prevent equipment failure.
Regularly scheduled inspections and maintenance tasks are performed to prevent breakdowns
Replacement of worn out parts before they fail to avoid costly repairs
Helps in increasing the lifespan of equipment and reducing downtime
Examples include changing oil in a car engine, cleaning air filters in H
Belt length can be calculated using the formula: L = 2C + (πD)
Measure the distance around the pulleys (C)
Measure the diameter of the larger pulley (D)
Use the formula L = 2C + (πD) to calculate the belt length
For example, if C = 30 inches and D = 10 inches, then L = 2(30) + (3.14)(10) = 60 + 31.4 = 91.4 inches
Types of pulleys commonly used in conveyors include drive pulleys, idler pulleys, and snub pulleys.
Drive pulleys are used to transmit power from the motor to the conveyor belt.
Idler pulleys are used to support and guide the conveyor belt.
Snub pulleys are used to increase the angle of wrap around the drive pulley to improve traction.
Other types of pulleys may include bend pulleys, take-up pulleys, and wing pulleys.

Various types of joints used in engineering include welded joints, bolted joints, riveted joints, and adhesive joints.
Welded joints involve fusing two materials together using heat or pressure.
Bolted joints use bolts and nuts to secure two materials together.
Riveted joints involve using rivets to connect two materials.
Adhesive joints use adhesives to bond materials together.
