Abstract
An electrode for a corona discharge apparatus is comprised of a conductor, which can be a stainless steel tube or filament, a metal bar or a rotatable roll, and which is covered by a dielectric, which can be an organic elastomer having a high dielectric constant or quartz or ceramic. The dielectric may be coated with a dielectric adhesive that is loaded with a granulated inorganic dielectric. In most applications a film resistor is inserted between the conductor and the dielectric to reduce any voltage spikes that can result if the corona discharge excites a resonant circuit.
