corona discharge

n.
An electrical discharge characterized by a corona and occurring when one of two conducting surfaces (such as electrodes) in a gas is shaped such that it concentrates the electric field at its tip and ionizes the surrounding air.

corona discharge

n
(General Physics) an electrical discharge appearing on and around the surface of a charged conductor, caused by ionization of the surrounding gas. Also called: corona See also Saint Elmo's fire

coro′na dis`charge


n.
a discharge, frequently luminous, at the surface of a conductor or between two conductors of the same transmission line, accompanied by ionization of the surrounding atmosphere and often by a power loss.

There are four usual types of PDs reported until now: (1) the first one is an internal PD in insulation material with different types of cavities [3, 4]; (2) the corona discharge is a PD produced by sharp edges [4, 5]; (3) electrical arborescence is generated by the combination of the corona discharge and superficial PD; (4) superficial PDs occur when there is effort on the surface of the dielectric, and usually they are presented in caps, cable ends, and the overheating of the generator windings and if a discharge reaches the surface from the outside [4, 5].
