PROBLEM TO BE SOLVED: To sense a current through a conductor.SOLUTION: A sensor includes a non-magnetic substrate defining an aperture structured to receive a conductor therein, a coil comprising a plurality of turns wound about the substrate, and a housing for enclosing the substrate and coil. The housing includes a dielectric material having a dielectric constant and positioned adjacently to the coil and at least partially within the aperture such that the dielectric material is disposed between the coil and the conductor when the conductor is received through the aperture, and a spacer coupled to the aperture to facilitate maintaining a position of the coil relative to the conductor, where each of the spacers is positioned offset from the dielectric material so as not to radially extend between the coil and the conductor.SELECTED DRAWING: Figure 1 |
