SYSTEMS AND METHODS FOR REDUCING ATTENUATION IN CURRENT TRANSDUCERS

摘要

A device includes a first axial ring, a first radial ring disposed below the first axial ring and a second radial ring disposed below the first axial ring. The first radial ring and the second radial ring are spaced apart in a radial direction. The device also includes an electrically non-conductive isolating ring disposed between the first axial ring and the first radial ring and a current sensor disposed between the first radial ring and the second radial ring. Further, the device includes a second axial ring disposed below the first radial ring, the second radial ring, and the current sensor. The first axial ring, the first radial ring, the second radial ring, and the second axial ring form a magnetic shield and an electrically conductive shell around the current sensor. The isolating ring disrupts the electrical continuity of the electrically conductive shell.
