摘要： A conductor lifter adapted to be mounted to a tower for temporarily supporting an energized conductor comprises a support arm having a base end and an opposite cantilevered end and a crank arm pivotally mounted on the cantilevered end, the crank arm having lower and upper crank arms. A first actuator is coupled to the support arm, and an elongate member is mounted to, so as to extend between, the upper crank arm and a first driver of the first actuator so as to rotate the crank arm about the pivotal coupling when the first actuator is actuated. A lower end of the lower crank arm is selectively elevatable by a second actuator relative to the upper crank arm so as to elevate a conductor when held by a conductor retainer on an insulator mounted to the lower crank arm. A method for using the conductor lifter is also provided.

摘要： A manipulator for separating sub-conductors in an energized single phase bundle includes a rigid support member and first and second actuators mounted on the support member, wherein each actuator is independently actuable of the other. Insulators are mounted on each actuator. A selectively releasable coupler is mounted on each insulator for selectively releasable coupling of each insulator to a corresponding sub-conductor. The actuators extend corresponding insulators independently of one another from the support member to thereby separate from each other by an optimized separation distance the distal ends of each insulator. When the corresponding sub-conductors of the single phase bundle are releasably coupled to the corresponding distal ends of the insulators the surge impedance loading of the single phase bundle may be improved by separation of the corresponding distal ends of the insulators and the sub-conductors by the optimized separation distance.

摘要： A system for non-destructive testing of an overhead energized electrical component. The system has a base, an X-ray source, an X-ray digital imager, and an imager controller. The system also has a removable electrically conductive flexible shield which is adapted to be operatively coupled to, and to encapsulate, at least the base, the X-ray source, the X-ray digital imager and the imager controller so as to form a shrouded system. In a use position, when the shrouded system is positioned adjacent the energized electrical component so as to non-destructively test the energized electrical component, the shield protects at least the base, the X-ray source, the X-ray digital imager and the imager controller from electric fields around the energized electrical component while allowing signal communication between at least the X-ray source and the energized electrical component.

摘要： An electrical isolator includes a flexible non-electrically conductive membrane and an inelastic flexible dielectric member journalled 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.

The DC leakage current is a composite DC current. The insulating structure is operatively coupled to at least an overhead energized DC electrical line. The system further includes a direct current meter adapted to be electrically coupled to at least the insulating structure. The meter includes a waveform separator. The separator is configured to receive and separate the composite DC current into a corresponding direct current (DC) and an alternating current (AC) component. The separator further includes at least one comparator which is configured to produce at least one corresponding digital signal from the AC component; and a processor. The processor receives and analyzes the at least one corresponding digital signal and the DC component to determine a resultant leakage current flowing through the insulating structure.

摘要： Systems, methods and apparatus to increase the frequency and/or probability of use of a personal safety device, and to reduce the probability that a person is exposed to a dangerous situation unless and until a safety device has been engaged. One apparatus includes an alarm that is activated by the use of a mechanized instrument to remind a worker using the instrument to engage a safety device before proceeding to use the instrument, and an actuator for a switch that can be used by the worker to deactivate the alarm. Another apparatus includes a switch to prevent operation of a mechanized instrument unless a safety device is engaged by a worker using the device, and an actuator for a switch that can be used by the worker to permit operation of the instrument. In a mechanized instrument, another apparatus includes a plurality of sensors that measure distances between themselves, and a microprocessor to activate an alarm concerning engagement of a safety device before operation of the instrument and/or to prevent use of the instrument until a safety device is engaged.
