In this work, we focus on the electrical properties of arcs of length of a few millimeters at a current level of 2 A. The computation is based on a unified non-equilibrium model that resolves the entire inter-electrode region, applies a deformed mesh to simulate the contact opening, and couples the heat transfer to the electrodes. The arcs are burning in atmospheric pressure air at the presence of Cu metal vapour. Experimental findings are used to calibrate the model.
