What Is A Corona Ring
The corona rings, also called corona control rings, they can be used in high voltage test equipment and power systems (substations, high voltage transmission line, AC voltage system, etc.) and are mainly made of aluminum alloy.
Generally the corona ring needs to be polished bright to achieve more smooth and no burr surface finish to ensure better corona control effect.
Corona ring is widely used on the end fittings of high voltage bushings and other high voltage testing equipments. High voltage can result in unwanted noise and corona, so corona rings are needed.
Corona ring is suitable for the voltage form of alternating current (AC), which can distribute the high voltage evenly around the object to ensure that there is no potential difference (PD) between the various parts of the ring.
