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: Power line transient suppressing circuits which use inductors in series w the load to reject or attenuate transients on the power line over a wider range of transients than with prior devices, and also serve as inrush current limiters. Two unidirectional current circulating diode-inductor loop circuits eliminate the 60Hz voltage drop across the inductors. Normal operation is not affected by the circuits, but transients are rejected by the inductors.

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.
