Abstract: The current sensor arrangement has a sensor (3) for detecting the magnetic field induced by the current, evaluation electronics (4) for the sensor signal and a current converter coil (2) enclosing the conductor section (1a) with an annular, high permeability core (5) for supplying power to the evaluation electronics. The core contains the sensor so as to act as a screen for the sensor against external magnetic fields.
