  • SYSTEMS AND METHODS FOR DETECTING OVERHEAD LINE MOTION
    Publication number: 20140136140
    Abstract: A system for monitoring motion of an overhead line includes a monitoring device. The monitoring device includes an accelerometer and a processing circuit. The processing circuit is configured to accept data from the accelerometer corresponding to line movement, analyze the data to determine displacement data corresponding to a displacement of the overhead line, accept data corresponding to a location of at least one external object proximate to the overhead line, and analyze the displacement data to determine a clearance from the at least one external object.

  • Method and apparatus for storing energy
    Patent number: 8686578
    Abstract: An energy storage apparatus for storing energy transmitted by a power transmission line includes an elastically deformable component and an actuator-generator. The actuator-generator is coupled to the elastically deformable component such that electrical actuation of the actuator-generator generates tension in the elastically deformable component. The actuator-generator is further coupled to the elastically deformable component such that mechanical actuation of the actuator-generator via a release of tension in the elastically deformable component causes a generation of electrical energy by the actuator-generator.
