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： Embodiments and methods relate to pulling and installing a product line along an underground arcuate path beneath an obstacle, including pulling the product line for an extended length (i.e. a length that might otherwise be deemed impracticable) along the underground arcuate path beneath the obstacle. A sealing/locking mechanism is located at one end of an outer pipe and at an end of an inner pipe at a position within the underground arcuate path.

摘要： A valve in conjunction with an actuator has a valve position indicator coupled to the actuator. The valve position indicator has an indicator cover mounted over an indicator mounting surface, an array of LED lights arranged on the indicator mounting surface, and a mirror mounted internal and concentric to the indicator cover. A sensor in communication with the actuator and the plurality of LED lights communicates the position of the valve to the plurality of LED lights. The plurality of LED lights may illuminate to indicate an incremental degree that the valve is open, if any, and/or indicate by color the direction that the opening (or respective closing) of the valve is changing. In another embodiment with or without the mirror equiangular spaced single points of light each have one high intensity LED oriented to emit light horizontally and one high intensity LED oriented to emit light vertically.

摘要： A boom mountable breaker system and a method of using same for interrupting electrical transmission through a portion of an energized conductor downstream of a desired break location. The method includes: mounting the jumper onto the energized conductor across the desired break location so as to form an electrically conductive first parallel electrical path; installing an in-line opener in the energized conductor at the desired break location on the energized conductor; positioning the breaker at the desired break location on the energized conductor, and electrically connecting the breaker, while open, across the desired break location and across the opposite ends of the jumper so as to form a second parallel electrical path when the breaker is closed; closing the breaker to thereby complete the second parallel electrical path; removing the jumper from across the desired break location; and, opening and then removing the breaker.
