  • Patent number: 9739807
    Abstract: Two cylindrical capacitors of different values are created in series within a single dielectric resin body to form a capacitive voltage divider for a Medium Voltage sensor. By eliminating temperature variance both capacitors' permittivity is the same, and consistent measurements may be achieved. A first capacitor in the picofarad capacitance range is formed by a rod-shaped central primary conductor, one layer of a wrapped foil capacitor as a second conductor, and the resin body as a dielectric. The wrapped foil capacitor provides a second capacitor in the nanofarad capacitance range and is also embedded within the resin body. The resin body provides a dielectric material almost impervious to ambient changes in operating range and allows for a compact design. A precision resistor can be added in parallel to the first and second capacitors to damp transients and increase the transformation ratio.

  • Patent number: 8796547
    Abstract: Systems and methods are provided for early detection of wire/cable faults. For example, a system may detect electrical/electronic faults with power lines, data lines, communication lines, coaxial cables, and the like (generally referred to herein as “lines”, “wires”, and “cables”) by providing sacrificial materials including a conductive material external to the lines. A processor may be coupled to the conductive material to transmit a control signal along the conductive material of the line to determine whether the line is degrading. That is, when the sacrificial material wears away and exposes the conductive sacrificial material in the line, that conductive material may begin to experience faults. The faults in the external conductive material may serve as precursors to the overall degradation of the line. Thus, the line may be repaired or replaced prior to the degradation of the line itself.

    Abstract: In the present invention, the solid contacted ISE and the solid contacted reference are based on a conductive porous network with a solid contact and membrane disposed thereon. The porous networks are not only mechanically stable, but also provide pore structure for the solid contact and membrane to intercalate, which enhances the life time and stability of the sensors. The invention further incorporates a unique fluidic fitting sensor and sealing mechanism so that measurements can be taken at high pressures. The fitting design has many benefits, such as low cost and disposability, which allows them to be mass manufactured. These sensors can be produced for detection of many different kinds of ions by applying different types of ion selective membranes, including polyvinylchloride (PVC) based ion-selective membranes and fluorous matrixes based ion-selective membranes.

  • Patent number: 8710364
    Abstract: The bend of the invention makes it possible to provide a great number of different direction changes in the configuration of gas-insulated high-voltage lines. The bend mainly uses an angled ferrule (11). associated with two angular rings (12), placed between the angled ferrule (11) and a straight section (13) of the line, each angular ring (12) forming a change of direction defined by a determined angular offset angle (?) between said two joining surfaces. Thus, the use of an angled ferrule (11), in combination with one or two angular rings (12) makes it possible to obtain the four angular offsets of 70°, 80°, 100°, 110°. These same angular rings (12), used with an angled ferrule having an angle of 140° makes it possible to obtain the angles of 120°, 130°, 150°, and 160°. Use for constructing gas-insulated high-voltage lines.

  • Patent number: 8344246
    Abstract: Aspects of the invention pertain to cooling bundles of power distribution cables or other current carrying cables. Such cables give off heat, especially when carrying high current loads. One or more cooling members are used to secure multiple cables. The cables may be placed about a generally circular shaped member which has a central opening. Receptacles are placed along an outer perimeter of the cooling member to secure the cables. The thickness of each cooling member may vary. When multiple cooling members are used, they may be spaced at least 6 inches apart. The cooling members may be fabricated from a nonconductive material such as PVC.

  • Publication number: 20120281332
    Abstract: The present invention is provided to satisfy insulation and conductivity performance requirements, to reduce the size of a gas insulated bus, and also to make conditioning for a particle more reliable. In a gas insulated bus having a conductor supported in a cylindrical metal container via an insulator, insulating gas being contained in the metal container, the metal container has an expanded diameter part formed over a given range in an area of the metal container in which the insulator is positioned and a reduced diameter part formed over the entire area of the metal container except for the expanded diameter part. Thus, when the temperature of the insulator increases during conduction, heat from the insulator is transferred to the metal container via a large space in the expanded diameter part and released to the air through a large outer surface of the expanded diameter part of the metal container.

  • Patent number: 8278556
    Abstract: Stabilization of dielectrics used in transmission lines is described. In one implementation, the transmission line includes an outer conductor, a center conductor, and a dielectric material. The dielectric material separates the outer conductor from the center conductor. The center conductor has a conductive surface with a pattern distributed thereon. The pattern is configured to prevent the dielectric material from moving when the transmission line is exposed to an extreme temperature fluctuation. The pattern increases a coefficient of friction between the center conductor and dielectric material sufficient enough to prevent undesired motion of the dielectric material. In one implementation, the pattern includes indentations that are generally, but not necessarily limited to between 0.001 and 0.004 of an inch deep.
