Abstract:
A current sensor includes a ferromagnetic core having a substantially central opening for receiving a current conductor and at least two gaps portions, each of the gap portions having an associated gap spacing. A detector of the current sensor includes at least one first sensing element disposed in a first one of the gap portions and configured to generate a respective first magnetic field signal in response to a first magnetic field generated in the first gap portion in response to a current through the current conductor. The detector also includes at least one second sensing element disposed in a second one of the gap portions and configured to generate a respective second magnetic field signal in response to a second magnetic field generated in the second gap portion in response to the current through the conductor. A method of sensing a current through a current conductor is also provided.
