I applied via Referral and was interviewed before Apr 2020. There was 1 interview round.
Power factor improvement involves reducing reactive power and increasing active power to improve efficiency.
Power factor is the ratio of active power to apparent power
Improving power factor reduces energy costs and improves system efficiency
Methods for improving power factor include capacitor banks, synchronous motors, and static VAR compensators
3-phase induction motor slip ring and squirrel cage motor differ in rotor construction and starting torque.
Slip ring motor has external resistors and brushes to control rotor current and torque, while squirrel cage motor has a simple rotor with copper bars.
Slip ring motor has high starting torque and is used in heavy load applications like cranes and elevators, while squirrel cage motor has low starting torque and is u...
Slip ring motors use external resistors for starting and speed control, while squirrel cage motors rely on the number of poles and frequency for speed control.
Slip ring motors have external resistors that are gradually removed to increase speed
Squirrel cage motors rely on the number of poles and frequency for speed control
Slip ring motors are used in applications where high starting torque is required
Squirrel cage moto...

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease the voltage in an electrical circuit.
They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.
The primary winding receives electrical energy from a power source, while the secondary ...
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).
Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.
They are made up of diodes, which allow current to flow in only one direction.
Rectifiers can be half-wave or full-wave, depending on the number of diodes used.
Examples of rectifiers include bridge rectifiers, vacuum tube rectifiers, and soli

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two coils of wire, known as primary and secondary coils
Primary coil receives electrical energy and creates a magnetic field
Magnetic field induces a voltage in the secondary coil, transferring energy
Used in power distribution, voltage regulation, and electrical isolation

I applied via Company Website and was interviewed before Jan 2023. There was 1 interview round.
The question is asking about the current of a unit.
The current of a unit refers to the amount of electric current flowing through a specific unit or device.
It is typically measured in amperes (A) or milliamperes (mA).
The current of a unit can vary depending on the specific device or circuit being discussed.
For example, the current of a unit could refer to the current flowing through a resistor, a transistor, or a motor...
Transformers are rated in KVA (kilovolt-amperes) to indicate their power capacity.
KVA stands for kilovolt-amperes, which is a unit of apparent power.
The KVA rating of a transformer indicates the maximum amount of power it can handle.
Transformers are available in various KVA ratings to suit different power requirements.
Higher KVA ratings indicate higher power capacity.
For example, a transformer with a 100 KVA rating can
Loop law, also known as Kirchhoff's voltage law, states that the sum of the voltages in any closed loop in a circuit is zero.
Loop law is a fundamental principle in electrical engineering.
It is also known as Kirchhoff's voltage law (KVL).
According to loop law, the algebraic sum of the potential differences (voltages) around any closed loop in a circuit is always zero.
It is based on the principle of conservation of energ...

I applied via Naukri.com and was interviewed in Nov 2020. There were 3 interview rounds.
To analyse total diesel consumption in equipment, I would gather data on usage and calculate fuel efficiency.
Collect data on equipment usage and fuel consumption
Calculate fuel efficiency by dividing fuel consumption by equipment usage
Compare fuel efficiency across different equipment to identify outliers
Identify factors that may affect fuel efficiency, such as maintenance or operator behavior
