Abstract

A remote sensing and communications system for installation on energized high voltage conductors is disclosed herein. The sensor modules are capable of measuring electrical, mechanical or environmental parameters in the vicinity of a high voltage conductor. The module digitizes and communicates the measured quantities via a communications subsystem mounted on and powered by an energized high voltage conductor without requiring a circuit interruption. Communications to a Central or Regional dispatch center at any desired distance from the sensing location is achieved using Ku-band or C-band spread spectrum satellite communications, or using the Geosynchronous Orbiting Environmental Satellites (GOES), or through fiber optic communications links. Individual subsystem modules are generally toroidal in shape and can be mounted on an energized high voltage conductor using a hot-stick or other means. The energized conductor current flow and electromagnetic field is used to generate a regulated power supply for the sensor module electronics. All the electronic components within the unit are protected by a signal conditioning network to preclude destruction of components in the event of lightning strike or other overvoltage conditions.
