DESCRIPTION
FIELD OF THE INVENTION

The present disclosure relates to the electrical systems, and more particularly, embodiments of the disclosure relate to an earthing electrode for earthing of electrical systems.

BACKGROUND OF THE INVENTION

Despite increasing developments in electrical sciences, the technique in which an electrical system is earthed has not changed. Earthing or grounding is a process of connecting an electrical system, such as an electrical system of a house or an office, with earth. The connection is generally made using a thick wire connected to a plate or a rod fixed in ground. The earthing system protects a building and individuals from electrical shock and increase safety of the structure. Further, the earthing system stabilized voltage of the electrical system and protect from surges.

Conventionally, a metal plate or a metal rod is driven into earth and the wiring system is attached thereto for permanent grounding. Generally, charcoal and salt are added to soil around the metal plate or rod. However, such compounds are corrosive in nature. Consequently, the metal plate or rod is corroded and overall conductivity of the grounding system decreases significantly. Further, maintenance of such grounding systems is often ignored and purpose of the earthing system is reduced. Furthermore, as the metal plate or rod is buried underground, checking for corrosion is extremely difficult.

Therefore, in light of the foregoing discussion, there exist problems associated with conventional earthing systems.
