Low consumption Flux-gate transducer for AC and DC high-current measurement

This work presents the design and implementation of a transducer system for the measurement of AC and DC high-current using the flux compensation technique in the measurement transformer, also called Flux- gate technology. The system can measure currents greater than 700 A (peak value) with a 100 kHz bandwidth measured at -3 dB. This equipment has been developed under the agreement of collaboration subscribed between the EUETIB-CEIB of the Technical University of Catalonia (UPC) and Group PREMO S.A. The Group PREMO S.A. is a Spanish company specialized in high-quality inductive components and leader in this sector.
