I applied via Campus Placement and was interviewed in Jan 2024. There was 1 interview round.
Induction motors work on the principle of electromagnetic induction to generate rotating magnetic fields.
Induction motors have a stator with a set of windings 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 currents in the rotor bars, causing it to rotate.
The rotor never catches up to the speed of the rotating...
Illumination refers to the amount of light present in a space, measured in lux or foot-candles.
Illumination is crucial for visibility and safety in indoor and outdoor environments.
It is measured using units such as lux or foot-candles.
Proper illumination levels are important in workplaces, homes, and public spaces.
Examples of illumination sources include natural light, light fixtures, and streetlights.
Switch gear is a combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment.
Switch gear is used to control the flow of electricity in a power system.
It is essential for protecting electrical equipment from damage due to overloads or short circuits.
Common applications of switch gear include power distribution, industrial plants, and electrical subst
Transformers are classified based on their construction, cooling methods, and voltage levels.
Based on construction: Core type and Shell type transformers
Based on cooling methods: Oil immersed, Dry type, and Water cooled transformers
Based on voltage levels: Step-up and Step-down transformers
Examples: Distribution transformer, Power transformer, Auto transformer

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers work on the principle of electromagnetic induction
They have primary and secondary coils wound around a core
Step-up transformers increase voltage while step-down transformers decrease voltage
Efficiency of a transformer is determined by its core material and design
Synchronous motor is a type of AC motor where the rotation of the shaft is synchronized with the frequency of the supply current.
Synchronous motor has a rotor with electromagnets and stator with field windings.
The rotor rotates at the same speed as the rotating magnetic field produced by the stator.
It requires DC excitation to create a magnetic field in the rotor.
Used in applications where constant speed is required, s
Torque variation in squirrel cage motors is achieved by changing the rotor resistance.
Torque in squirrel cage motors can be varied by changing the rotor resistance.
Increasing the rotor resistance will increase the torque produced by the motor.
Decreasing the rotor resistance will decrease the torque produced by the motor.
This method is commonly used in applications where variable torque is required, such as in fans or p
Speed and torque variation methods are used in electrical systems to control the performance of motors.
Speed variation methods include changing the frequency of the power supply or using variable speed drives.
Torque variation methods involve adjusting the voltage or current supplied to the motor.
Examples of speed variation methods include VFDs (Variable Frequency Drives) and soft starters.
Examples of torque variation m...

Resistance is the opposition to the flow of electric current, while machines are devices that convert energy from one form to another.
Resistance is measured in ohms and is caused by the material and dimensions of a conductor.
Machines include motors, generators, transformers, and other devices that use electrical energy to perform work.
Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is vo
Machines operate based on various principles such as electromagnetic, mechanical, thermal, and chemical principles.
Machines convert one form of energy into another to perform work
Electromagnetic machines use the principles of electricity and magnetism, like motors and generators
Mechanical machines use moving parts to transfer and transform energy, like engines and gears
Thermal machines use heat to generate power, like ...
Challenges in electrical industry include rapid technological advancements, safety concerns, and skilled labor shortage.
Rapid technological advancements leading to constant need for upskilling and training
Safety concerns related to electrical hazards and compliance with regulations
Skilled labor shortage impacting project timelines and quality of work
Integration of renewable energy sources and smart grid technologies

M15 ratio is the mix ratio of cement, sand, and aggregate in construction.
M15 ratio is commonly used in construction for preparing concrete.
It refers to the mix ratio of 1:2:4, which means 1 part cement, 2 parts sand, and 4 parts aggregate.
This ratio is suitable for general construction purposes where high strength is not required.
Initial setting time of rhc is the time taken for the cement paste to lose its plasticity and become rigid.
Initial setting time is typically around 30 minutes for ordinary Portland cement.
It is influenced by factors such as temperature, water-cement ratio, and type of cement used.
Testing for initial setting time is done using the Vicat apparatus.
It contains basic logical reasoning questions
