Modelling of magnetic current sensors for measuring high AC and DC currents

摘要

This paper proposes a general model of magnetic current sensors for measurement of high AC and DC currents. The model is a functional description and decomposition of a typical current transducer based on magnetic field sensing. Each function is described in its various practical realisations. Starting from the model of existing magnetic current sensors, an innovative approach is described. The innovative solution is promising for application in power multiconductor systems, when low cost and a large measuring range are required.
