I applied via Walk-in and was interviewed in Aug 2023. There was 1 interview round.
MCB and overload relay are both electrical protection devices, but they serve different purposes.
MCB stands for Miniature Circuit Breaker and is used to protect electrical circuits from overcurrents and short circuits.
Overload relay is used to protect motors and other electrical equipment from excessive current that can cause overheating and damage.
MCB operates based on the principle of thermal and magnetic tripping, w...
A soft starter is a device used to gradually start and stop the motor by controlling the voltage applied to it.
Soft starters are used to reduce the starting current and torque of an electric motor.
They provide a smooth and controlled acceleration and deceleration of the motor.
Soft starters can be used in various applications such as pumps, fans, and conveyor belts.
They typically consist of power electronics, control ci...
A drive is a device that reads and writes data to storage media, allowing users to access and store information.
Drives can be internal or external, such as hard disk drives (HDDs) or solid-state drives (SSDs).
They use various technologies like magnetic or flash memory to store data.
Drives are connected to a computer or device through interfaces like SATA, USB, or PCIe.
They have controllers that manage data transfer and...
Star delta starters are used to reduce the starting current of induction motors.
Star delta starters are used in applications where the starting current needs to be limited.
They are commonly used in industries where large motors are employed.
By starting the motor in star configuration, the current is reduced to one-third of the delta configuration.
This helps in preventing excessive voltage drop and reduces stress on the...
The protection of a transformer involves various measures to ensure its safe and reliable operation.
Overcurrent protection: Protects against excessive current flow.
Overvoltage protection: Guards against high voltage surges.
Under/over frequency protection: Monitors and controls the frequency of the input power.
Temperature protection: Prevents overheating by monitoring the transformer's temperature.
Buchholz relay protect...

A circuit diagram of hydraulics shows the flow of hydraulic fluid through a system of valves, cylinders, and pipes.
Hydraulic pump: generates pressure to move fluid through the system
Valves: control the direction and flow rate of the fluid
Cylinders: convert fluid pressure into mechanical force
Pipes: transport the fluid between components
Pressure gauges: monitor the pressure levels in the system

Preventive maintenance is scheduled maintenance to prevent breakdowns while predictive maintenance uses data to predict failures.
Preventive maintenance involves regularly scheduled maintenance to prevent equipment breakdowns and prolong the lifespan of equipment.
Predictive maintenance uses data analysis to predict when equipment failure is likely to occur, allowing for maintenance to be scheduled before a breakdown occ...
PLC stands for Programmable Logic Controller and HMI stands for Human Machine Interface.
PLC is a digital computer used for automation of electromechanical processes.
It is used to control machinery on factory assembly lines, amusement rides, or light fixtures.
HMI is a graphical interface that allows humans to interact with machines.
It provides a visual representation of the process being controlled by the PLC.
Examples o...
