Earthing Systems: These systems ensure that electrical installations are properly grounded, preventing electric shocks and ensuring the safety of electrical systems during faults.
Key Components:
Earth Rods and Electrodes:
Purpose: Installed deep into the ground to disperse electrical energy safely into the earth.
Materials: Typically made from copper, galvanized steel, or stainless steel.
Earth Conductors and Cables:
Purpose: These are cables that connect the electrical system to the earth rods, allowing the safe transfer of current to the ground.
Materials: Copper or aluminum.
Earth Pit Covers:
Purpose: Protect the grounding connection points and make them accessible for maintenance.
Materials: Cast iron, concrete, or plastic.
Chemical Earthing Electrodes:
Purpose: Provide a low-resistance grounding system using conductive compounds, especially in dry or rocky soil conditions.
Materials: Copper-bonded rods with a mixture of chemical salts.
Lightning Protection Systems: Lightning protection systems are designed to capture and safely direct the immense electrical energy from lightning strikes to the ground, preventing damage to structures and electrical equipment.
