I applied via Walk-in and was interviewed in May 2024. There were 2 interview rounds.
Electrical engineering Moderate level questions.
Induction motors work by inducing a current in the rotor through electromagnetic induction.
Induction motors have a stator with coils that are connected to an AC power source.
When the AC power is applied, it creates a rotating magnetic field in the stator.
This rotating magnetic field induces a current in the rotor, causing it to rotate.
The rotor does not have any electrical connections and relies on induction to generat...
Types of starters used in electrical engineering for controlling the starting of motors.
Direct On-Line (DOL) starter
Star-Delta starter
Auto-transformer starter
Soft starter
Variable frequency drive (VFD) starter
A motor is a device that converts electrical energy into mechanical energy to produce motion.
Motors can be classified into different types such as AC motors and DC motors.
Common examples of motors include induction motors, synchronous motors, and brushed DC motors.
Motors are used in various applications such as industrial machinery, household appliances, and automotive systems.
I applied via Naukri.com and was interviewed before Mar 2023. There was 1 interview round.
An induction motor is a type of AC motor where power is supplied to the rotor by electromagnetic induction.
Consists of a stator and a rotor
Does not require any physical connection between the rotor and the stator
Commonly used in industrial applications for driving pumps, fans, compressors, and conveyor systems

I applied via Campus Placement and was interviewed before Jul 2022. There were 3 interview rounds.
Basic aptitude and reasoning test . Qualifying in nature. Anyone can clear it .
Types of transformers include step-up, step-down, isolation, autotransformer, and distribution transformers.
Step-up transformers increase voltage levels for long-distance transmission.
Step-down transformers decrease voltage levels for household use.
Isolation transformers provide electrical isolation between the input and output.
Autotransformers have a single winding with taps for different voltage levels.
Distribution t...
VFD stands for Variable Frequency Drive and is used to control the speed of an electric motor by varying the frequency and voltage supplied to it.
VFDs are commonly used in industrial applications to save energy and improve process control.
They are used in HVAC systems to control the speed of fans and pumps, resulting in energy savings.
VFDs can also be used in conveyor belts, compressors, and other motor-driven equipmen...
The protection system of a power transformer ensures its safe operation by detecting and mitigating faults.
Protection systems monitor various parameters of the transformer such as temperature, oil level, and winding currents.
Differential protection is commonly used to detect internal faults by comparing the currents entering and leaving the transformer.
Buchholz relay is used to detect and isolate faults in the oil-fill...
