In order to ensure the galvanic isolation of an electrical system following a manual operation or a default strike (overload, short circuit), current limitation properties of the electric arc are used, forcing a fast decrease to zero current. Modeling this process reveals complex, since it involves a large amount of physical phenomena (radiation, phase transitions, electromagnetism, fluid dynamics, plasma physics). In order to get a robust solving, enhancing strongly coupled resolution and time constants compatibility, the Finite Volume Method has been chosen,. This method was first implemented on intrinsic electromagnetism problems (current flow, magnetostatics including non-linear materials, and magnetodynamics), for which energy-based pr...
