Diffrence between chemical earthing and Conventional earthing

 

The main difference between chemical earthing and conventional earthing lies in the materials used to create the earthing system.

Conventional earthing, also known as plate earthing, uses a copper or galvanized iron plate buried in the ground, along with a number of interconnected rods to create a low resistance path for current to flow to the ground. This type of earthing is simple and cost-effective, but may not be effective in areas with high soil resistivity.

Chemical earthing, on the other hand, involves the use of a conductive electrode surrounded by a layer of conductive backfill material that is chemically infused with salts and minerals. This creates a low resistance path for current to flow to the ground, regardless of the soil resistivity. The electrode used in chemical earthing is typically made of copper-bonded steel or galvanized iron.

Some of the key differences between chemical earthing and conventional earthing include:

Performance: Chemical earthing typically provides better performance than conventional earthing, particularly in areas with high soil resistivity.

Maintenance: Chemical earthing requires less maintenance than conventional earthing, as the backfill material and electrode are designed to resist corrosion and remain conductive over time.

Cost: Chemical earthing is typically more expensive than conventional earthing due to the cost of materials and installation.

Installation: Chemical earthing requires specialized equipment and expertise for installation, while conventional earthing can be installed with basic tools and equipment.

Overall, while chemical earthing may be more expensive to install, it provides better performance and requires less maintenance over time, making it a good option for applications where reliable and long-lasting earthing is required.
