Earthing is an important safety measure in electrical systems.
Earthing provides a path for fault current to flow safely to the ground.
There are different types of earthing systems such as TN, TT, and IT.
The number of earthing points depends on the type of system and the size of the installation.
For example, a small domestic installation may have one earth rod, while a large industrial installation may have multiple ear...
The five types of earthing are: plate earthing, pipe earthing, rod earthing, strip earthing, and water pipe earthing.
Plate earthing involves burying a metal plate in the ground and connecting it to the electrical system.
Pipe earthing uses a metal pipe driven into the ground and connected to the electrical system.
Rod earthing utilizes a metal rod driven into the ground and connected to the electrical system.
Strip earthi...

Electrical questions
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC). Three-phase connection refers to a system that uses three conductors to carry three alternating currents that are out of phase with each other.
Rectifiers are commonly used in power supplies and electronic devices to convert AC to DC.
Three-phase connections are used in industrial and commercial settings to power large moto...
AC and DC supplies differ in their voltage polarity and frequency.
AC voltage changes direction periodically while DC voltage flows in one direction only.
AC voltage has a frequency typically of 50 or 60 Hz while DC voltage has a constant voltage level.
AC voltage is used for power transmission over long distances while DC voltage is used for electronic devices.
AC voltage can be easily stepped up or down using transformer...
