Line-mounted, movable, power line monitoring system

Abstract

A mobile system for monitoring electrical, physical and/or environmental parameters and conditions associated with or in proximity to an energized electrical power conductor supported on a succession of towers extending along a power corridor. In a first embodiment, the system includes front and rear propulsion modules surrounding the conductor and carrying a payload module therebetween. The propulsion modules include linear induction or rotary DC motors deriving power directly from the power conductor. The payload module carries equipment such as video and infrared cameras, and apparatus for lightning flash, ambient temperature, acoustic and corona detection, and a transmitter for relaying appropriate signals to a remote ground station. In another embodiment, the payload module is mounted upon a lightning shield wire of the power line and is connected to a propeller-driven helium blimp for movement along the wire. In both embodiments, the line-mounted equipment includes appropriate apparatus which allows movement thereof past obstructions on the line.
