A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease voltage levels in electrical circuits.
They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.
The primary coil is connected to the input voltage source, while the secondary coil is connected to the output load.

An encoder is a device or software program that converts data from one format to another.
An encoder can be used to convert analog signals to digital signals or vice versa.
Encoders are commonly used in robotics, industrial automation, and digital communication systems.
Examples of encoders include optical encoders, magnetic encoders, and rotary encoders.
A motor is a device that converts electrical energy into mechanical energy to produce motion.
Motors can be found in various applications such as industrial machinery, household appliances, and vehicles.
There are different types of motors including AC motors, DC motors, and servo motors.
Motors work by creating a magnetic field that interacts with current-carrying conductors to generate force and motion.
AC VVFD stands for Alternating Current Variable Voltage Variable Frequency Drive.
AC VVFD is a type of motor controller that varies the voltage and frequency of the electrical supply to control the speed of an AC motor.
It is commonly used in industrial applications to regulate the speed of pumps, fans, conveyors, and other equipment.
AC VVFDs can improve energy efficiency, reduce wear and tear on equipment, and provide p...

Different types of loads applied on long and short steel columns
Long columns are more susceptible to buckling under compressive loads
Short columns are more susceptible to crushing under compressive loads
Long columns are more likely to experience bending under lateral loads
Short columns are more likely to experience shear under lateral loads
Examples of loads include dead load, live load, wind load, seismic load, etc.
I applied via Walk-in and was interviewed before Jun 2021. There were 2 interview rounds.
An antipumping relay is used to prevent the breaker from repeatedly closing and opening in case of a fault.
The antipumping relay is a protective device used in circuit breakers.
It prevents the breaker from 'pumping' or repeatedly closing and opening due to a fault.
When a fault occurs, the relay detects the fault current and prevents the breaker from reclosing until the fault is cleared.
This helps to protect the electri...
