Abstract :
This paper presents a method to study the dynamics of an arc from magnetic measurements. The mathematical model developed enables us to reconstitute the evolution of a low-voltage, self-blown arc assimilated to a succession of current elements. It also enables us to analyze restrike phenomena for which one might suppose there exists a current exchange between an arc located at the top of the electrodes and another one located in a zone where there remains some possibility of conduction
