I applied via Campus Placement and was interviewed in Sep 2024. There was 1 interview round.
IDMT relay is used for overcurrent protection while transformer differential relay is used for differential protection.
IDMT relay operates based on inverse time-current characteristic curve
Transformer differential relay compares the currents entering and leaving the transformer windings
IDMT relay is used for protecting electrical equipment from overcurrents
Transformer differential relay is used for detecting internal f
Solar panels convert sunlight into electricity through photovoltaic cells.
Solar panels contain photovoltaic cells that convert sunlight into electricity
When sunlight hits the cells, it excites electrons, creating a flow of electricity
The electricity generated can be used to power homes, businesses, or stored in batteries for later use

Online aptitude test was easy. Questions were asked on electrical only.
Types of rotors in generators include salient pole rotor and cylindrical rotor.
Salient pole rotor has projecting poles with concentrated windings, used in low-speed applications.
Cylindrical rotor has distributed windings and is used in high-speed applications.
Other types include wound rotor and squirrel cage rotor.
Wound rotor has three-phase windings connected to slip rings, used in variable speed applications.
Squirrel...
Star delta starter is a type of reduced voltage starter used for starting high power motors.
Consists of two contactors - one for star connection and one for delta connection
Reduces starting current and torque on the motor
Commonly used in industrial applications for motors above 5 HP
Types of transformer losses include copper losses, iron losses, and stray losses.
Copper losses: Also known as I^2R losses, occur in the copper windings of the transformer due to resistance.
Iron losses: Also known as core losses, occur in the transformer core due to hysteresis and eddy currents.
Stray losses: Occur due to leakage flux and imperfect magnetic coupling between the windings.
Examples: An example of copper los...
A generator works on the principle of electromagnetic induction to convert mechanical energy into electrical energy.
Generators use a magnetic field and a conductor to create a flow of electrons, generating electricity.
When the conductor moves through the magnetic field, it induces a current in the conductor.
This current is then collected and transferred through wires to power electrical devices.
Examples of generators i...

Nice experience easy moderate questions
I appeared for an interview in Sep 2024.
Basic logical reasoning questions were asked, with a greater emphasis on quantitative aptitude.
An Astable Multivibrator is a type of oscillator circuit that generates a continuous square wave output.
Consists of two transistors cross-coupled through capacitors and resistors
No stable state, continuously switches between high and low states
Capacitors charge and discharge alternately, creating oscillations
Commonly used in applications like signal generators, LED flashers, and tone generators
The VI characteristics of a pn junction diode show the relationship between voltage and current flowing through the diode.
The graph shows a non-linear relationship between voltage and current, with forward and reverse bias regions.
In forward bias, the diode conducts current easily with a small voltage drop, while in reverse bias, it blocks current flow until breakdown voltage is reached.
The knee voltage in the forward ...
