Types of Earthing
There are various ways of doing EARTHING:
Conventional EARTHING
* Pipe Earthing,
* GI Plat Earthing,
* Cast Iron plat Earthing,
* Copper plat Earthing
Maintenance Free EARTHING
Conventional Earthing:
The Conventional system of Earthing calls for digging of a
large pit into which a GI pipe or a copper plate is
positioned amidst layers of charcoal and salt. It is
cumbersome to install only one or two pits in a day.
The Conventional system of GI pipe Earthing or copper plate
Earthing requires maintenance and pouring of water at
regular interval.
Maintenance free earthing:
It is a new type of earthing system which is ready made,
standardized, scientifically developed.
Advantages of Free earthing:
Maintenance Free: No need to pour water at regular
interval- except in sandy soil.
Consistency: Maintain stable and consistent earth
resistance around the year.
More Surface Area: The conductive compound creates a
conductive zone, which provides the increased surface area
for peak current dissipation. And also get stable reference
point.
Low earth resistance. Highly conductive. Carries high
peak current repeatedly.
No corrosion. Eco Friendly.
Long Life.
Easy Installation.
