A power system is a network of electrical components used to generate, transmit, and distribute electrical power.
Power systems consist of power plants, transformers, transmission lines, and distribution networks.
They are designed to deliver electricity from power plants to consumers.
Power systems can be categorized into three main types: generation, transmission, and distribution.
Examples of power systems include the e...
The formula for I squared R is used to calculate the power dissipated in a resistor.
I squared R is equal to the current (I) squared multiplied by the resistance (R)
It is commonly used in electrical engineering to determine the power loss in a resistor
For example, if the current flowing through a resistor is 2A and the resistance is 5 ohms, the power dissipated can be calculated as (2^2) * 5 = 20 watts
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 consist of diodes that allow current to flow in only one direction.
Rectifiers are used in various applications such as battery charging, electroplating, and welding.
Examples of rectifiers include half-wave rectifiers, full-wave rectifie
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, called the primary and secondary, wrapped around a magnetic core.
When an AC current flows through the primary coil, it creates a magnetic field that ind...

I applied via Walk-in and was interviewed in Jun 2022. There were 3 interview rounds.
CT and PT are electrical transformers used in power systems to measure current and voltage respectively.
CT stands for Current Transformer and is used to measure high currents in power systems.
PT stands for Potential Transformer and is used to measure high voltages in power systems.
CTs are connected in series with the load while PTs are connected in parallel with the load.
CTs are used to measure current for protection a...

I applied via Naukri.com and was interviewed in Jan 2021. There was 1 interview round.
I applied via Walk-in and was interviewed in Jul 2023. There were 2 interview rounds.
To protect a transformer, measures such as overcurrent protection, temperature monitoring, and proper grounding should be implemented. VFD stands for Variable Frequency Drive, a device used to control the speed of an electric motor.
Implement overcurrent protection to prevent excessive current flow through the transformer.
Monitor the temperature of the transformer using temperature sensors to prevent overheating.
