I applied via Whatsapp and was interviewed in May 2024. There were 2 interview rounds.
The minimum megger value of a good motor is typically 1 megohm or higher.
A good motor should have a megger value of at least 1 megohm to ensure proper insulation resistance.
Lower megger values may indicate insulation issues or potential breakdowns in the motor.
Regular megger testing is important to detect any insulation problems in motors.
For high voltage motors, the minimum megger value may be higher than 1 megohm.
The kVA transformer installed in the plant is 500 kVA.
The kVA transformer installed in the plant is 500 kVA.
The kVA rating of the transformer is crucial for determining the power capacity of the plant.
It is important to regularly check and maintain the transformer to ensure optimal performance.
The kVA rating indicates the maximum load that the transformer can handle without overheating.

The maximum voltage of transmission line in India is 765 kV.
The highest voltage level in India is 765 kV.
This voltage level is used for long distance transmission of electricity.
India has several high voltage transmission lines, including the Raigarh-Pugalur HVDC line.
The maximum voltage level has increased over the years, from 400 kV to 765 kV.
Higher voltage levels allow for more efficient transmission of electricity.
Various methods like V/F control, rotor resistance control, and vector control are used for speed control of induction motors.
V/F control method varies the frequency and voltage supplied to the motor to control its speed.
Rotor resistance control method involves inserting external resistance in the rotor circuit to control the speed.
Vector control method uses advanced algorithms to control the speed and torque of the mo...

D.O.L starter stands for Direct-On-Line starter.
D.O.L starter is a type of motor starter used in electrical systems.
It is commonly used to start induction motors.
The full form of D.O.L is Direct-On-Line.
It is also known as a full voltage starter.
In a D.O.L starter, the motor is directly connected to the power supply without any intermediate devices.
It provides a simple and cost-effective method of motor starting.
D.O.L ...
Power factor is a measure of how effectively electrical power is being used in a circuit.
Power factor is the ratio of real power (in watts) to apparent power (in volt-amperes).
It indicates the efficiency of electrical power consumption in a circuit.
A power factor of 1 means all the power is being used effectively, while a power factor less than 1 indicates wastage of power.
Inductive loads like motors and transformers h...
A sensor is a device that detects and responds to physical input from the environment.
Sensors are used to measure and monitor various physical quantities such as temperature, pressure, light, and motion.
They convert the physical input into an electrical signal that can be processed and analyzed.
Examples of sensors include thermocouples, photodiodes, accelerometers, and proximity sensors.
Sensors are essential in many in...
