I applied via Company Website and was interviewed in Dec 2024. There were 2 interview rounds.
VFD stands for Variable Frequency Drive, used to control the speed of an AC motor by varying the frequency and voltage supplied to the motor.
VFDs are commonly used in industrial applications to control pumps, fans, and other motor-driven equipment.
They can improve energy efficiency by adjusting motor speed to match the required load.
VFDs can also provide better control over motor acceleration and deceleration, reducing...

RCCB stands for Residual Current Circuit Breaker, a device designed to quickly disconnect power in the event of a leakage current.
RCCB is a safety device used to protect against electric shock and fire hazards.
It detects any imbalance in the electrical current flowing through the circuit.
When a leakage current is detected, the RCCB trips and disconnects the power supply.
RCCBs are commonly used in residential, commercia...

I applied via Company Website and was interviewed in Jul 2023. There was 1 interview round.
An encoder is a device or circuit that converts information from one format to another.
An encoder can be a hardware device or a software program.
In the context of electrical engineering, an encoder is often used to convert analog signals into digital signals.
Encoders are commonly used in communication systems, robotics, and industrial automation.
Examples of encoders include rotary encoders used in motor control and opt
I applied via Walk-in and was interviewed in Mar 2022. There were 2 interview rounds.
An encoder is a device that converts motion into an electrical signal. A proxy is a server that acts as an intermediary for requests from clients.
Encoders are used in various applications such as robotics, automation, and CNC machines.
Proxies are commonly used in computer networks to improve security and performance.
An example of an encoder is a rotary encoder that converts the rotational motion of a shaft into an elec...
To check a transformer, perform visual inspection, measure voltage and current, and test insulation resistance.
Perform a visual inspection of the transformer for any physical damage or signs of overheating.
Measure the voltage and current using a multimeter to ensure they are within the rated values.
Test the insulation resistance using a megohmmeter to ensure it is above the minimum value.
Perform a polarity test to ensu...
To check motor conditions, perform visual inspection, measure voltage and current, check for abnormal noises, and test motor performance.
Perform a visual inspection to check for any physical damage or loose connections.
Measure the voltage and current using a multimeter to ensure they are within the specified range.
Listen for any abnormal noises such as grinding or squealing that may indicate motor issues.
Test the motor...
VFD drives are used to control the speed and torque of electric motors, resulting in energy savings and improved motor performance.
VFD drives allow for precise control of motor speed and torque.
They can be used to match the motor speed to the load requirements, resulting in energy savings.
VFD drives can improve motor performance by reducing mechanical stress and wear.
They enable soft starting and stopping of motors, re...
ACB and VCB breakers are both types of circuit breakers used in electrical systems, but they differ in their operating mechanisms.
ACB stands for Air Circuit Breaker, while VCB stands for Vacuum Circuit Breaker.
ACB breakers use air as the medium for arc extinction, while VCB breakers use vacuum.
ACB breakers are typically used for low voltage applications, while VCB breakers are used for medium to high voltage applicatio...
Di and Do are electrical protection devices used in low voltage systems to protect against overcurrent and short circuits.
Di stands for Differential Current Protection and is used to detect and protect against ground faults and leakage currents.
Do stands for Overcurrent Protection and is used to protect against overloads and short circuits.
Di works by comparing the current flowing in the live and neutral conductors, an...
