摘要： The invention relates to an arrangement for measuring the current in an electric conductor (1) with a magnetic circuit (2) for coupling with the electric conductor (1) which comprises an air gap (3). A magnetic field sensitive component (4) is located in the air gap (3) of the magnetic circuit (2) for measuring the magnetic field created by the electric conductor (1), wherein two control cores (5) are disposed in the air gap (3) of the magnetic circuit (2), wherein the control cores (5) each have one control winding (6) for the magnetic saturation of the respective control core (5). The magnetic field sensitive component (4) is disposed between the control cores (5) and one or more additional elements (7) are located in the vicinity of the magnetic field-sensitive components (4), said additional elements being suitable for guiding interfering magnetic fields in the area surrounding the magnetic field-sensitive component (4), independently of the control cores (5).

摘要： The invention relates to an arrangement for measuring a current flowing through an electrical conductor (1), said arrangement comprising a magnetic circuit (2) comprising an air gap (3), for coupling to the electrical conductor (1). A component (4) sensitive to a magnetic field is arranged in the air gap (3) of the magnetic circuit (2), said component being used to measure the magnetic field generated by the electrical conductor (1). A control core (5) is arranged in the air gap (3) of the magnetic circuit (2), said control core (5) comprising a control winding (6) for the magnetic saturation of the control core (5). A plurality of additional elements (7a, 7b) are arranged close to the component (4) sensitive to magnetic fields, said elements being used to guide parasite magnetic fields generated around the component (4) sensitive to magnetic fields, independently of the control cores (5).
