Systems and methods for distributed sensing of a powerline conductor

Abstract:

A system includes (1) a signal transmitter that includes (a) a radio frequency generator that generates a first radio frequency electromagnetic signal and (b) a first transducer that converts the first radio frequency electromagnetic signal to a surface wave mode signal imposed onto a powerline conductor at a first location in a first direction toward a second location along the powerline conductor, (2) a signal receiver that includes a second transducer located at the second location that converts the surface wave mode signal into a second radio frequency electromagnetic signal, and (3) an analysis subsystem that monitors a signal strength of the second radio frequency electromagnetic signal over time to determine whether a physical encroachment of the powerline conductor exists between the first location and the second location.
