A corona device comprising a multiplicity of electrode pins embedded in a body of insulating material has each pin projecting from two sides of the insulating body and has this body disposed between two conductive elements, or electrodes, which are connectable to the opposite poles of a voltage source. The ends of each pin are in the electric field between the electrodes at locations between which a high potential difference is present, so that a corona discharge may develop between each end of a pin and the related electrode. The corona device may also comprise provisions for inhibiting deterioration of the pin ends subject to positive corona discharge, and/or for counteracting the positive potential so that no positive corona discharge will occur.
