Around high-voltage power lines, hum may be produced by corona discharge.

Such a device may use the principle of electro-aerodynamic pumping, which is based on corona discharge.

The corona discharge between the object and the high voltage plate is captured by the film.

It also has a high dielectric breakdown and is resistant to corona discharge.

Their experiments went up to 133,000 volts; they observed corona discharge along the transmission lines.

The ozone gives the blast its characteristic corona discharge like smell.

There are also processes involving oxygen plasma and corona discharge.

Therefore, power transmission equipment is designed to minimise the formation of corona discharge.

In high tension rollers, particles are charged by a corona discharge.

It works on the principle of corona discharge, where two plates are placed close together and high voltage is applied.
