ABSTRACT:
A corrona test set has at least a reactor and power separation filter placed in an oil-filled conductive tank of a conductive material such as sheet steel. The exciter optionally may also be placed in the same tank enclosure which is of much smaller size than the equivalent voltage rating test set in air. High voltage taken from the circuit passes out of the tank through high voltage bushings. A preferred form of bushing is a quick coupling cable receiving device having an insulator extending into the tank and a frustoconical metallic extension extending away from the tank with a tubular internal wall connected to these respective parts at opposite ends to form a further oil-filled compartment separate from the tank. A temporary cable termination may be applied to a cable which enables a tubular outer piece to supply rigidity and guidance within the tubular inner wall of the bushing to facilitate contact between the bushing high voltage conductor at the insulator at the tank end of the bushing and the coaxial conductor within the cable. A clamping and sealing ring is provided to hold the terminated cable in position so the demineralized and deionized water can be circulated through the entire space between the cable itself and the inner wall of the oil-filled bushing compartment.
