Abstract

In this paper, we present an original method, which allows reconstituting the current density in a low voltage breaker arc. This method is based on the deconvolution of magnetic induction measurements and a function depending on the experimental device geometry. We propose two deconvolution methods: an iterative method using minimization by gradient and the direct method using Fourier transform. The two methods will be compared to choose the one, best adapted, for the arc study.
