Abstract: A dielectric corona ring to provide field shaping by spreading or deconceating an electric field for reduction or elimination of ionization of air near a high voltage insulator.

Abstract: An electrostatic charge generator for continually providing charge carriers f 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.

Abstract: An automatic electrical load matching device for applying loads to wind den generators. The device switches five different loads to the output of a wind driven generator. Each load corresponds to a range of speeds of the wind driven generator's rotor.

Abstract: A modular lightweight, high voltage guyline insulator for VLF antennas. A glass fiber or "Kevlar" rod tension member that provides high tensile strength is enclosed by a porcelain jacket, which serves as a good high voltage insulator, preventing an arc breakdown along the surface and protecting the tension member from exposure to ultraviolet radiation which could cause the tension member to deteriorate. A rubber sleeve extends between each end of the porcelain jacket and a guyline fastening means, and together with the porcelain jacket forms a cavity or chamber around the tension member which is filled with SF.sub.6 gas, pressurized to 2 to 4 atmospheres (29.4 psia to 58.8 psia). Metal strips and metal toroid corona rings act to diffuse the electric field.

Abstract: An electrostatic high potential device which utilizes the generation of etrostatic charges on moving oil to produce a high potential difference on the order of thousands of volts. A metal encased ionizing device or charge generator with a system of passageways of dielectric material has an oil moving therethrough and against the dielectric material to cause a transfer of electric charges between the oil and passageway surfaces. The passageways act as baffles and provide a large amount of surface contact between the oil and dielectric material. The conductive housing of the ionizing device is grounded to draw off the charges on the dielectric material, and a pump circulates the charged oil from the ionizing device to a charge storage device of similar design. Electrodes in the charge storage device draw off the charges on the oil.
