Abstract: A current transducer for measuring the flux from a current carrying conductor, the current transducer comprising a sensor core for concentrating magnetic flux from said current carrying conductor, the sensor core being shaped as a loop broken by a gap. The current transducer further comprises a fluxgate ring core for sensing the magnetic flux, and two excitation coils for generating excitation flux in the ring core and for detecting the magnetic flux of the current carrying conductor. Drive means for driving an excitation current through the excitation coils are present along with a detection circuit connected to the excitation coils for detecting the electronic signal of the excitation coil. The fluxgate ring core is arranged in the gap of the sensor core, and the excitation coils are wound around a first and a second part of the fluxgate ring core, respectively.
