A corona ring, also known as a grading ring, is a metallic conductive ring installed on high-voltage power line fittings and insulators to reduce electric field concentration and suppress corona discharge. By evenly distributing the electric field, it minimizes radio interference, power loss, and premature aging of insulators, ensuring reliable performance in overhead transmission systems.
