1.Design:
1)They are typically metal toroids that attach to terminals or other parts of the equipment to prevent corona discharge by keeping the electric field below the threshold where corona would occur.
2)These rings are essential for maintaining the integrity and performance of high voltage transmission insulators and switchgear.
2.Application:Corona rings are commonly used in high voltage applications to prevent corona discharge. They are found on:
1)Electric power transmission insulators
2)Switchgear
3)Scientific research apparatus that generates high voltages, such as Van de Graaff generators, Cockcroft–Walton generators, and particle accelerators.
