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 levels in electrical power transmission and distribution systems.
Synchronous machines are AC machines that operate at a constant speed and are used for power generation.
Induction machines are AC machines that operate at variable s...

Power triangle is a graphical representation of the relationship between real power, reactive power, and apparent power in an AC circuit.
Real power is represented by the horizontal side of the triangle
Reactive power is represented by the vertical side of the triangle
Apparent power is represented by the hypotenuse of the triangle
The angle between the real power and apparent power sides represents the power factor
Ohm's Law relates voltage, current, and resistance. Thevenin's Theorem simplifies complex circuits into a single voltage source and resistor.
Ohm's Law: V = I * R (voltage = current * resistance)
Thevenin's Theorem: Any linear circuit can be simplified to a single voltage source and resistor
Example: Ohm's Law can be used to calculate the current flowing through a resistor in a circuit
Example: Thevenin's Theorem can be us...

I applied via Company Website and was interviewed before Nov 2021. There were 2 interview rounds.
The motor capacity refers to the maximum power output of the motor.
Motor capacity is measured in horsepower (HP) or kilowatts (kW).
It determines the maximum load the motor can handle.
For example, a motor with a capacity of 5 HP can handle a heavier load than a motor with a capacity of 3 HP.
The motor capacity should be chosen based on the requirements of the application.
I applied via Job Fair and was interviewed in Sep 2024. There was 1 interview round.
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
Ohm's Law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.
It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.
For example, if a circuit has ...
Transformer protection refers to the measures taken to ensure the safe operation of transformers and prevent damage.
Overcurrent protection: Protects against excessive current flow.
Overvoltage protection: Safeguards against high voltage levels.
Overtemperature protection: Prevents overheating of the transformer.
Differential protection: Detects internal faults by comparing input and output currents.
Buchholz relay: Detects...

Motor protection is a system designed to prevent damage to motors from electrical faults or overloads.
Motor protection devices include overload relays, thermal protectors, and circuit breakers.
These devices monitor the current and temperature of the motor to prevent overheating and damage.
Motor protection also involves proper grounding, insulation, and regular maintenance to ensure safe operation.
Examples of motor prot...

Power factor is a measure of how effectively electrical power is being converted into useful work output.
Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical system.
It is a number between 0 and 1, with 1 representing perfect efficiency.
Low power factor can result in increased energy costs and inefficient use of electrical power.
Power factor correction can be implemented to improve effic...
Power factor is the ratio of actual power to apparent power in an electrical system.
Power factor is a measure of how effectively electrical power is being used in a system.
It is calculated by dividing the actual power (in watts) by the apparent power (in volt-amperes).
A power factor of 1 indicates perfect efficiency, while a lower power factor indicates inefficiency.
For example, if a system has an actual power of 800W ...
