Abstract

See full text

A powerline sensor including a housing physically and electrically connectable to a powerline; a number of voltage sensing devices spaced peripherally about the housing, each voltage sensing device having an outer plate, an inner plate, and a dielectric material between the inner and out plates, the inner plates electrically connectable to the powerline, the outer plates electrically isolated form the powerline; and circuitry for sensing the voltage potential between the inner and outer plates to determine the voltage on the powerline.
