Preventing locally destructive electrical field densities on rotation symmetrical electrode arrangement involves attenuating field with metal bead on region immersed in process liquid

摘要

The method involves providing the high voltage electrode with an annular metal bead on a region immersed in a process liquid to attenuate the local electric field. The high voltage electrode extends into an end tip exposed to a counter electrode in a reaction vessel. A dielectric insert displaces the field onto the floor of the reaction vessel.
