Definitions

  • My invention relates to carrier-current linetraps, such as are inserted as a part of an overhead conductor of an alternating-current transmission-line, for the purpose of permittin the free passage of the Gil-cycle or line-frequency currents, while impeding the passage of super-imposed carrier-currents, of a carrier-current frequency or radio-frequency, said carrier-currents being utilized for protective relaying-communication, remote metering or switching, or for other purposes.
  • carrier-current iine-traps consist of choke-coils, made of heavy conductorcable adapted to carry the full line-currents, this coil being supported on a hollow cylindrical insulating support having a tuning-unit inside of the same, for providing the capacitor-branch of a parallel-resonant carrier-frequency circuit, the Other branch of which is the choke-coil itself.
  • My invention has particular relation to carrier-current line-traps which utilize a plurality of capacitors, of assorted sizes, which may be connected together in various series, parallel, and series-parallel combinations, for controlling the amount of capacity which i effective, and thus provide a means for tuning the trap to the particular carrier-current frequency which is being employed.
  • connection-block or terminal-board, for such carrier-current line-traps, whereby the terminal-connections may be made quickly and easily, without Wires; and can be made with a minimum of skill, from the standpoint of the purchaser; and whereby a connection-block construction is provided which makes it a simple and economical matter for the manufacturer to provide the necessary water-tight or weather-resistant construction which is required of all carrier-current line-traps.
