Abstract

The presented study concerns the dynamics of the arc in a low-voltage breaking device. For this study, two methods of diagnostics are used: a magnetic diagnostics based on punctual measurements of the induction and an optical diagnostics using a high-speed camera and a CCD camera. These two diagnostics are compared for different experimental conditions.
