摘要： A partial discharge detecting device includes an electric field sensor including: a first electrode configured to detect by capacitive coupling a partial discharge signal generated by an electrical object and to provide a corresponding first electrical signal, and a second electrode isolated from the first electrode and structured to detect an environmental noise and to provide a corresponding second electrical signal. The detecting device further includes a transmission line structured to propagate an output signal obtained from the electric field sensor toward an external analysis apparatus and an electronic module connected to the first and second electrodes and structured to process the first and second electrical signals and to provide the output signal to the transmission line. The electronic module is structured to decouple the electric field sensor from the transmission line and avoid resonance of the electric field sensor with the transmission line.

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： In a magnetic particle testing procedure, a spring loaded prod with contact points prevents arc strikes from occurring between the prod and a part under test. Positive pressure is applied to the prod which engages the contacts before current can flow to the part. Similarly, in removing the prod from the part with the prod power switch depressed, the arcing will occur in the prod assembly and not on the part under test.

摘要： The conductivity cell consists of a first set of electrodes fixed rigidly to a second set of electrodes. Each set of electrodes has an insulating material support with an electrode well through it, and three spaced electrodes positioned sequentially within the well. In one embodiment, the support is a glass tube and the three electrodes are deposited on the inner surface of the glass tubes. In a further embodiment, the three electrodes are washer shaped conductive strips fixed within the electrode well and spaced by two washer shaped non-conductive strips also fixed within the electrode well. Each set of electrodes further includes a glass tubing fixed within the electrode well between each outer electrode and the outer end of the electrode well. In another embodiment, washer shaped electrodes are recessed in the wall of the electrode well such that the surface of the strips are flush with the electrode well surface. The two outer electrodes are electrically connected together as well as electrically insulated from the center electrode. The two outer electrodes carry current through the sea water between the wells while the center electrode in each well is a voltage electrode. The two wells may be substantially parallel and the cell may further have a temperature sensing device.

摘要： A moisture tester for grain and like materials is disclosed. The tester includes a walled test chamber including spaced apart electrodes which form an electrical coaxial capacitor, the electrodes being located so that the dielectric constant of the capacitor is modified in accordance with the dielectric constant of a test material sample introduced into the test chamber. To limit the volume, and to configure and pack the volume of test material introduced into the tester in a predetermined way, a funnel arrangement is provided at the tester top. A lower portion of the funnel directs inflowing grain over an axially aligned, centrally located finger which forms one of the electrodes. A pour spout is provided for pouring test sample material from the test chamber after test completion.
