Current measurement in the time domain based on the inversion of magnetic field data

In order to reconstruct a system of currents flowing in parallel conductors by processing magnetic field data in the time domain, the positions of the magnetic sensors have to be carefully chosen. In this article, the locations of the sensors are determined so that the imaginary part of the kernel matrix can be neglected. The reconstruction errors given by the approximated model are investigated both in a periodic regime and in a transient state, which are typical, respectively, of over-load and short-circuit conditions in power systems.
