摘要： A remotely controlled unmanned aerial device for use in proximity or in contact with high voltage powerlines, includes an unmanned aerial vehicle and an electrically conductive shield forming part of or operatively coupled to so as to encapsulate the unmanned aerial vehicle. When in the presence of a high voltage powerline, the unmanned aerial vehicle either when bonded-on or within the corresponding magnetic fields of the powerline, so as to transfer the powerline potential in whole or in part to the unmanned aerial vehicle, electrically energizes the conductive shield around the unmanned aerial vehicle while leaving components of the unmanned aerial vehicle within the shield substantially electrically unaffected by the voltage potential.

摘要： A method and apparatus for calculating line sag in a span of a conductor is provided. The method includes using a portable smart device having one or more accelerometers and running a line sag application on the processing device. The line sag application enables acceleration data of return waves generated on the conductor to be collected using the smart device and to be plotted as a function of time for display on the smart device. The method further includes placement of time markers on the plotted data displayed on the smart device to determine elapsed time and calculating line sag using the elapsed time.

摘要： An endless track vehicle with increased traction and/or installation, modification, and/or use of track cleats for traction for the endless track of the endless track vehicle. A body is mountable to the endless track exterior. The body defines bores extending from a first end of the body to a second end of the body, wherein the bores have counterbores. First and second cleats/bolts respectively having a cleat/bolt heads, the cleats/bolts mounted in respective bores and optional extending out a distance out of the second end of the body, wherein the cleat/bolt heads seat in the respective counterbores. Nuts may be used in the counterbores to optionally extend the cleats/bolts, and/or to secure and fasten the cleats/bolts.

摘要： An apparatus and method measures and analyzes DC current passing through a substantially insulating member or dielectric material that is electrically connected to, or otherwise conductive, between an energized DC electrical transmission line and an Earth potential or ground. An apparatus may utilize a DC current measuring device, a DC voltage level selection switch, a DC display, a graphical display of momentary leakage current, and an audio speaker. A process may entail extending a substantially insulating member or dielectric material between an energized DC electrical transmission line and an Earth potential, detecting a DC momentary leakage current, using a DC momentary leakage current meter to measure DC current through the member or material, and a computer to analyze and compare the DC current, and deliver results or a warning that the DC current has reached a threshold value.

摘要： A continuous processing system and method for the continuous processing of an electrical conductor cable having aluminum strands encasing a steel core directly from a puller or from a puller and reel, simultaneously or on-the-fly during substantially the entirety of a reconductoring or re-stringing of the cable, wherein such cables are used for power lines or for static wires. The system is adapted to cooperate with a pulling machine. The pulling machine may be formed integrally within the system or may be a conventional pulling machine which cooperates with the system. The processing system runs continuously, substantially without interruption, during the pull of all of the cable from the pull zone of the reconductoring or restringing.

摘要： An electrical isolator includes a flexible non-electrically conductive membrane and an inelastic flexible dielectric member journaled in the membrane and extending from the first end of the membrane to the second end of the membrane. First and second couplings are mounted to the ends of the dielectric member. The ends of the membrane are mated in sealed engagement with the couplings so as to fluidically seal the ends of the membrane and the dielectric member within the membrane. The membrane is filled with a dielectric fluid so as to displace any air in the membrane and the dielectric member. The couplings are adapted to couple to objects at opposite ends of the electrical isolator.
