At extremely high voltages, more than 2,000 kV exists between conductor and ground, corona discharge losses are so large that they can offset the lower resistive losses in the line conductors.
Film and digital imaging techniques also record light produced by photons emitted during corona discharge (see Mechanism of corona discharge ).
Gaseous ozone created by ultraviolet light or by corona discharge is injected into the water. citation Ozone is also widely used in treatment of water in aquariums and fish ponds.
In these generators, however, corona discharge from exposed metal parts at high potentials and poorer insulation result in smaller voltages.
The air in a region around a high-voltage conductor can break down and ionise without a catastrophic increase in current; this is called " corona discharge ".
The corona discharge between the object and the high-voltage plate is captured by the film.
