What is the function salt in the earthing installation?

In earthing installations, salt is often used to enhance the conductivity of the soil. When mixed with water and applied to the earth electrode, salt helps to lower the resistivity of the surrounding soil, improving the effectiveness of the grounding system. This increased conductivity ensures that electrical faults are safely dissipated into the ground, reducing the risk of electrical shock or equipment damage. However, it's important to monitor and maintain the salt levels, as they can wash away over time or cause corrosion.
