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 conductive sensing member supported by said substantially non-conductive core; (c) a first non-contact voltage sensor supported by said substantially non-conductive core; (d) a coupler that interconnects said first end portion and said second end portion; (e) a current sensing module that receives a first input signal from said conductive sensing member and estimates a current conductor signal within a conductor at least partially encircled within said elongate substantially non-conductive core material; (f) a voltage sensing module that receives a second input signal from said first non-contact voltage sensor and estimates a voltage conductor signal within said conductor said at least partially encircled within said elongate substantially non-conductive core material. |
