DC current measurement using magnetic flux in an electronic null balancing arrangement

DC current measurement using magnetic flux balancing with an automatic controller is presented. A ferromagnetic, toroidal core is used both as a flux detector and magneto motive force summer element. A symmetrical, AC triangular current seat through an excitation coil builds up flux in the core. The...
