The principle of the operation
Corona discharge is one of the three distinguished types of partial discharges i.e. breakdowns
caused by high voltage, which does not cause a short circuit. In addition to the corona discharge
(the least harmful of partial discharges), there are surface discharges, related mainly to
contaminated insulator surface and internal discharges caused by the degradation of the internal
insulation.
