Corona rings are used primarily as a control, or grading component, in the electrical utility industry for high voltage applications such as switches, substation bus hardware, and dead end assemblies on transmission lines. Such ring devices of various sizes and configurations act to reduce radio and television inteference which is a direct result of corona, a phenomenon created when the potential of a conductor in the air is raised to such a value that the dielectric strength of the surrounding air is exceeded.
