Corona Ring, High Voltage Insulator Fitting Manufacturer

Corona Ring

A corona ring also called an anti-corona ring, it is a toroid-shaped metal ring that is attached to a terminal of high voltage equipment. For system voltages 230kV and above, a corona ring is necessary. The primary role of the corona ring is to reduce corona discharge using corona rings which occur in high-voltage power lines.

Made from copper, steel, and aluminum the corona ring is packed in wooden case and cartons, Corona discharge occurs when there is an excessive localized electric field gradient as the diameter of the ring is inversely proportional to the voltage percentage of the lowermost insulators.

Corona discharge occurs in high power discharge lines using corona rings which can help reduce the corona discharge because they can damage the insulators and may produce breakdown products. To suppress the corona discharge, the wire-to-ring current flow is being formed up instead of wire-to-air.

The hot end of the stack will have a far more voltage drop across the insulators because of the stack of insulators used for EHV insulation.
