Corona discharge
Electric discharge generated in a gas, usually at atmospheric pressure, surrounding a conductor carrying a sufficiently high potential that the electric field around it ionizes the gas so as to form a plasma in the immediate vicinity of the conductor without causing complete electric breakdown or arcing.


Note: A corona discharge can also be sustained in a liquid.
