Why Is Earthing Or Grounding Important? Grounding is essential in an electrical installation to ensure safety and avoid serious consequences to people and equipment. A correct connection to physical earth provides the currents with a safe route and prevents these currents from finding unwanted routes that could cause damage. Why is earthing done in the

What Are The Reasons For The Increase In Earthing Resistance? Causes. Earth Potential Rise (EPR) is caused by electrical faults that occur at electrical substations, power plants, or high-voltage transmission lines. Short-circuit current flows through the plant structure and equipment and into the grounding electrode. How can we increase earth resistance? Increase the Rod Thickness.
