1. A coil for sensing a changing current comprising:
(a) an elongate substantially non-conductive core material having a first end portion and a second end portion; (b) a plurality of sensors positioned at a spaced apart location from one another and supported by said non-conductive core material; (c) a coupler that interconnects said first end portion and said second end portion; (d) a sensing module that receives a signal from each of said plurality of sensors and estimates a signal within a conductor at least partially encircled within said elongate substantially non-conductive core material based upon said signal from each of said plurality of sensors. |
