Dynamic properties of compensative current measuring systems enhancement

Original approach to compensative current measuring systems solution, based on the Hall effect and branched magnetic circuit application is presented in the paper. In the proposed solution, only a small fraction of a magnetic flux, excited by measured current, is compensated. Due to this, the number of turns of a compensative coil is dramatically reduced and yields much lower inductance of a compensative circuit. By decreasing the compensative circuit inductance, the dynamic properties of the system are significantly enhanced. Basic theoretical assumptions and formulas as well as experimental results are also presented
