TLDR
In this article, the cross sectional area of the magnetic core can preferably become greater with increasing distance from the gap, and the magnetic field sensor can be arranged in such a way that the pole face of the core can correspond to the active surface of the sensor.Abstract:
In an arrangement for the contactless measuring of the electric current in a conductor (1) in which a magnetic core (3) enclosing the conductor exhibits a gap in which a magnetic field sensor (5) is arranged, the pole face of the magnetic core essentially corresponds to the active surface of the magnetic field sensor. In this arrangement, the cross sectional area of the magnetic core can preferably become greater with increasing distance from the gap.read more
