Abstract
An electrostatic charge generator for continually providing charge carriersf a given polarity in a flow of dielectric fluid. The charge generator comprises a coaxial tube with an inner conductor wire coaxial with a hollow, cylindrical outer conductor. A D.C. potential is applied between the inner and outer conductors of the coaxial tube and a dielectric liquid, such as oil, is caused to flow therethrough. Since the intensity of the non-uniform electric field in the conductor tube is highest near the inner conductor, the electrostatic charges of the opposite polarity as the inner conductor are removed from the dielectric fluid faster than charges of the same polarity are removed at the outer conductor. This results in the dielectric fluid exiting the conductor tube carrying a charge of the remaining polarity.
