Introduction to Corona Rings
Corona rings, also known as grading rings, are essential components in high – voltage electrical systems. They are designed to control the electric field distribution around high – voltage conductors and insulators. By reducing the electric field intensity at sharp points or edges, corona rings help to prevent the occurrence of corona discharge. Corona discharge can cause power loss, radio interference, and damage to electrical equipment over time. Therefore, the quality and performance of corona rings are crucial for the reliable operation of high – voltage power transmission and distribution systems. Corona Rings
