Why might a ground ring be installed?

• A. To increase the risk of electrical faults
• B. To provide a larger surface area for grounding in areas with high soil resistivity
• C. To enhance insulation qualities
• D. To allow greater energy efficiency

Answer: (B)

A ground ring is installed primarily to provide a larger surface area for grounding in areas with high soil resistivity. This is crucial because high soil resistivity can hinder the effectiveness of a conventional grounding system, leading to insufficient grounding and increased risk of electrical faults. By utilizing a ground ring, which encircles the structure and connects to various grounding electrodes, the installation enhances the grounding system's ability to dissipate electrical charge into the earth. In locations where soil resistivity is a concern, a ground ring helps ensure that the grounding system functions effectively by increasing contact with the earth and reducing resistance. The larger surface area aids in achieving a lower resistance to ground, which is essential for safety and proper equipment operation. This solution is particularly valuable in environments with rocky soil, sandy soil, or any condition where traditional grounding methods may fall short.
