Abstract
An apparatus for use in sensing electrical current in a conductor includes a flux concentrator and one or more magnetic flux sensors. The flux concentrator includes main sections which are formed of a magnetic material. One or more intermediate sections, formed of a nonmagnetic material, extend between the main sections of the magnetic flux concentrator. The main sections and intermediate section of the magnetic flux concentrator cooperate to at least define an opening through which a portion of the conductor extends.
