Corona Ring Specification

Corona rings are 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.
