What Are The Reasons For The Increase In Earthing Resistance?
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.
