摘要： A sensor unit for the measurement of a current in a conductor (1) comprising at least one magnetoresistive sensor (5, 6) located at a radial distance from the outer surface of the conductor (1) is disclosed, wherein the conductor (1) has a circular cross-section, and wherein it comprises at least one auxiliary coil (7) for the generation of a bias magnetic field (Hbias) to the magnetoresistive sensor (5, 6) strong enough for inducing magnetic saturation in the magnetoresistive sensor (5, 6) continuously during the whole current measurement process. Further the use of such a sensor and a method for measuring the current in the conductor using such a sensor unit are disclosed.
