I applied via Campus Placement and was interviewed before Sep 2022. There was 1 interview round.
Wind turbines convert wind energy into electricity through the use of blades that spin a generator.
Wind turbines use the kinetic energy of the wind to generate electricity
Blades on the turbine spin a generator to produce electricity
Wind speed and direction are important factors for efficient turbine operation
Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.
Transformers work on the principle of electromagnetic induction
They consist of two coils of wire, known as the primary and secondary windings
The primary winding is connected to a power source, creating a magnetic field
This magnetic field induces a voltage in the secondary winding, transferr...

VCB, SF6, CT, PT, LA are all electrical equipment used in power systems.
VCB stands for Vacuum Circuit Breaker and is used for switching and protection of electrical power systems.
SF6 is a gas used as an insulating medium in high voltage electrical equipment such as circuit breakers, switchgear, and transformers.
CT stands for Current Transformer and is used to measure electrical current in power systems.
PT stands for Po...
Copper and aluminum are commonly used conductors in transmission.
Copper is an excellent conductor due to its high electrical conductivity.
Aluminum is also widely used as it is lightweight and cost-effective.
Other conductors like silver and gold are rarely used due to their high cost.
Copper-clad steel conductors are used in specific applications where strength is required.
Different types of tests related to transformers include routine tests, type tests, and special tests.
Routine tests are performed on every transformer and include measurement of winding resistance, insulation resistance, and voltage ratio.
Type tests are performed on a sample transformer to verify its design and include temperature rise test, impulse test, and short-circuit test.
Special tests are performed on transforme...
Different types of faults refer to the various abnormalities that can occur in an electrical system.
Short circuit fault
Open circuit fault
Ground fault
Overvoltage fault
Undervoltage fault
Overcurrent fault
Undercurrent fault
Relays are switches that open and close circuits electromechanically or electronically. There are various types of relays.
Electromechanical relays
Solid-state relays
Reed relays
Polarized relays
Time-delay relays
Overload protection relays
Mercury-wetted relays
Latching relays
Machine tool relays
Thermal relays
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
Transformers work on the principle of electromagnetic induction
They have two coils, primary and secondary, wound around a common magnetic core
When an alternating current flows through the primary coil, it creates a magnetic field which induces a voltage in the secondary coil
The voltage in...

I applied via Referral and was interviewed in Feb 2021. There were 4 interview rounds.
Switch gears are electrical devices used to control, protect and isolate electrical equipment.
Switch gears are used in power distribution systems to control the flow of electricity.
They protect electrical equipment from damage caused by overloads, short circuits, and other faults.
Switch gears can be classified into low voltage and high voltage depending on the voltage level they operate at.
Examples of switch gears incl...
