摘要： A system for determining the impact of moisture on a dielectric sealing material may include a testing apparatus having a testing chamber. A dielectric sealing material and a conducting pin may be exposed to the testing chamber. A first electrical lead may be coupled to the conducting pin, and a second electrical lead may be coupled to the dialectic material. An insulation resistance measurement unit may be coupled to both the first electrical lead and the second electrical lead, and the insulation resistance measurement unit may be configured to measure an insulation resistance value between the electrical leads. The insulation resistance measurement unit may measure a first insulation resistance value of the dielectric sealing material in a first environmental condition, and the insulation resistance measurement unit may measure a second insulation resistance value of the dielectric sealing material at a second environmental condition, that is different than the first environmental condition.

摘要： Propagating brush discharge testing systems may include a dielectric layer, an initiation electrode, a high-voltage switch, an optical sensor, and a controller. The initiation electrode has an exposed tip positioned adjacent to a surface of the dielectric layer. The high-voltage switch is configured to selectively isolate the initiation electrode from ground potential. The optical sensor is positioned and configured to sense light generated at the surface due to a propagating brush discharge. The controller is programmed to operate the high-voltage switch to ground the initiation electrode and to operate the optical sensor to collect light from the propagating brush discharge. Propagating brush discharge testing methods include positioning an exposed tip of an initiation electrode with respect to a surface of a dielectric layer, then charging the surface, and then grounding the initiation electrode to neutralize charge on the surface (generally causing a propagating brush discharge).

摘要： Provided is an apparatus for analyzing the state of oil-filled electrical devices. The apparatus simulates the state of an oil-filled electrical device in which copper wire wrapped in insulating paper is immersed in insulating oil. The apparatus for analyzing the state of oil-filled electrical devices includes a first paper-covered copper wire and a second paper-covered copper wire, which are adjacent to each other; a tank which holds the first and second paper-covered copper wires as well as insulating oil extracted from the oil-filled electrical device, thereby immersing the first and second paper-covered copper wires in the insulating oil; and a capacitance measurement unit which measures the capacitance between the first and second paper-covered copper wires. The first and second paper-covered copper wires includes copper wire and insulating paper wrapped therearound. The insulating paper wrapper around each copper wire includes the same material as the insulating paper in the oil-filled electrical device.

摘要： A test vessel assembly comprises a central test vessel defining a chamber in which a sample to be tested may be stored. A pair of side adjustable electrodes is received in the chamber and immersed in the sample under test to determine the breakdown voltage of the sample. A gap between the electrodes can be adjusted by respective electrode adjusting moved in and out of the test vessel by rotation of an associated adjusting wheel. To prevent the breakdown in air rather than in the sample, care is taken to ensure sufficiently large creepage and clearance distances between the connections to the electrodes and from the connections to the electrodes to a wall of the test chamber. To this end, the adjusting wheels include convolutions that mesh with corresponding convolutions in the test vessel.

摘要： A sensor for picking up partial discharges in an electrical equipment tank filled with a dielectric fluid includes an antenna responsive to the electromagnetic waves generated by such partial discharges. In the sensor, the antenna is formed by two electrodes that are separated from each other by a dielectric resonator. With this arrangement, the sensor has improved sensitivity in the UHF range, while being of dimensions that are considerably smaller than dimensions of a conventional antenna for use in the UHF range.

摘要： A method and an apparatus for touch-free testing of the insulating ability of an electric insulation on an electric conductor, where the testing item (8), the conductor, continuously is moved between a system of testing electrodes (2, 4), where the electric current path to the surface of the testing item is established by means of ionized atmospheric air, ion cloud or corona, between the testing electrodes (2, 4), made by a high frequenced high voltage generator (14) with low effect, where the testing item (8) is moved through the center of the electrode system (2, 4), that defects in the insulation are determined by means of a D.C. voltage established in an electric serial connection with the ion cloud, so that insulation defects in the testing item (8) will cause an electric current through the electric charge carrier in the form of ions, and that the electric current is registered by a current measuring circuit (18).

摘要： 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. Clamping and sealing means 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.
