Abstract: A current sensor includes a magnetic field sensing element, a first conductor including sandwich structure and second conductor including sandwich structure electrically coupled to one another. The magnetic field sensing element is interposed between the first and second sandwich structure. The magnetic field sensing element is operable to receive magnetic flux lines resulting from current flowing through the first and second conductor sandwich structure. The first and second conductor sandwich structure each include a top portion including at least a first electrical conductor, a bottom portion including at least a second electrical conductor, and a layer of magnetic permeable material different from the first and second electrical conductor interposed between the top portion and bottom portion.

Abstract: A current sensor includes a support structure (12), a magnetic field sensor (11) positioned on the support structure, a primary conductor comprising sandwich (13) including an electrically conducting top layer (13a) and electrically conducting bottom layer (13b), and a layer of magnetic permeable material (13c) interposed between. The magnetic permeable material (13c) is disposed around the magnetic field sensor (11) so that the magnetic field sensor (11) is at least partially surrounded by the magnetic permeable material (13c). The conductor sandwich (13) includes at least one gap (16, 17) between adjacent edges (18, 19). The magnetic field sensor (11) is positioned proximate to the gap and is operable to receive magnetic flux lines resulting from current flowing in the primary conductor.

Abstract: The method and circuit detects a current flow over the human body between a forward conductor and a return conductor, and disconnects the network conductors. The output signal emitted by a current sensor connected to a network conductor is detected and a switch for disconnecting the network conductor is then actuated only at a value of the signal of the current sensor between an upper and a lower threshold value.
