Abstract :
New idea of compensative, current measuring systems solution based on the Hall effect and branched magnetic circuit application is presented in the paper. In the proposed measuring method only a fraction of a magnetic pulse excited by measured currents is compensated by means of compensating current flowing through compensating coil. This solution yields much lower number of turns of compensating coil in comparison to other compensative type of measuring systems and dynamic features of the system are enhanced. Basic theoretical assumption and formulas as well as experimental results are also presented
