Summary:PROBLEM TO BE SOLVED: To provide sensor devices and related methods for accurately detecting an electric current.SOLUTION: A sensor device 12 includes a Rogowski coil 104 defining an aperture 110, and a dielectric material 108 at least partially enclosing the Rogowski coil. The dielectric material has a dielectric constant of at least about 3.5. The dielectric material is configured such that, when a conductor is at least partially inserted within the aperture, at least a portion of the dielectric material is positioned between the Rogowski coil and the conductor.
