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.
