Abstract
The invention is the use of a solid conductive polymeric composition, which displays a massive resistance increase upon exposure to an external fault condition, as one plate of a capacitor for a continuous sense and locate device. This resistance increase of the conductive polymeric composition (CPC) decreases the capacitance of the capacitor so as to provide an indication of the fault and its location.
