Claim Text:
1. A device, comprising: a first axial ring; a first radial ring disposed below the first axial ring in an axial direction; a second radial ring disposed below the first axial ring in the axial direction, wherein the first radial ring and the second radial ring are spaced apart in a radial direction perpendicular to the axial direction; an electrically non-conductive isolating ring disposed between the first axial ring and the first radial ring; a current sensor disposed between the first radial ring and the second radial ring; and a second axial ring disposed below the first radial ring, the second radial ring, and the current sensor; wherein the first axial ring, the first radial ring, the second radial ring, and the second axial ring form a magnetic shield and wherein the isolating ring disrupts electrical continuity of the first axial ring, the first radial ring, the second radial ring, and the second axial ring.
