Solar panels convert sunlight into electricity through the photovoltaic effect.
Solar panels are made up of photovoltaic cells that contain semiconductors like silicon.
When sunlight hits the solar panel, the photons in the light are absorbed by the semiconductors.
This absorption creates an electric current as the electrons in the semiconductors are excited and flow through the material.
The flow of electrons generates el...

The basic law governing transformers is the law of electromagnetic induction.
The law states that when the magnetic field around a conductor changes, an electromotive force (EMF) is induced in the conductor.
This EMF can cause a current to flow if the conductor forms a closed loop.
In a transformer, this principle is used to transfer electrical energy from one circuit to another through electromagnetic induction.
The prima...
Various losses in a transformer include copper losses, iron losses, and stray losses.
Copper losses occur due to resistance in the transformer windings.
Iron losses, also known as core losses, occur due to hysteresis and eddy currents in the transformer core.
Stray losses occur due to leakage flux and stray capacitance in the transformer.
Copper losses and iron losses are the major contributors to total losses in a transfo...
AC and DC are two types of electrical current. AC changes direction periodically while DC flows in one direction.
AC stands for Alternating Current and DC stands for Direct Current.
AC changes direction periodically, typically in a sinusoidal waveform.
DC flows in one direction only, maintaining a constant polarity.
AC is used for power transmission over long distances due to its ability to be easily converted to different...
An inverter is a device that converts DC power to AC power.
An inverter is commonly used in electrical systems to convert the direct current (DC) produced by sources such as batteries or solar panels into alternating current (AC) that can be used to power appliances and devices.
The basic working principle of an inverter involves the use of electronic components such as transistors to switch the DC input on and off rapid...
Solar panel installation requires several components including solar panels, inverters, mounting systems, wiring, and electrical protection devices.
Solar panels: These are the main components that convert sunlight into electricity.
Inverters: They convert the direct current (DC) produced by solar panels into alternating current (AC) that can be used in homes or fed into the grid.
Mounting systems: These are used to secur...
There are various types of circuit breakers with different uses and ratings.
Miniature Circuit Breaker (MCB) - used in residential and commercial buildings
Molded Case Circuit Breaker (MCCB) - used in industrial applications
Air Circuit Breaker (ACB) - used for high voltage applications
Ground Fault Circuit Interrupter (GFCI) - used to protect against electrical shocks
Residual Current Circuit Breaker (RCCB) - used to detec...
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.
