Apparatus for measuring an electric current flowing through an electrical conductor
First Claim
1. An apparatus for measuring an electric current flowing through an electrical conductor, comprising a measuring device which is arranged in the proximity of the electrical conductor and which detects the magnetic field generated by the electric current and supplies an electrical signal corresponding to the current strength, characterised in that the measuring device has a magnetic sensor device detecting the magnetic field in three orthogonal spatial directions, wherein the magnetic sensor device has magnetic field-sensitive transducers or sensors associated with the three orthogonal spatial directions, wherein measuring regions of different measurement sensitivities are associated with the various regions of the saturation curve of the respective magnetic material of the at least one magnetic circuit.
