This paper presents a method to simulate the current and voltage of an electric arc initiated at the contact's opening in a contactor. Based on a simplified model of the electric arc and also on the dynamics of the contacts during the opening, this method allows to simulate the arc ignition as well as the arc extinction. This study is based on the hypothesis that the arc dynamic is much faster than...
With the rising demand for electrical energy in an aircraft and the increase in operating voltages of the electrical distribution networks, the probability of occurrence of an arc fault is also increased. New protection devices such as arc fault detectors are now integrated in the network to break the circuit in case of an arcing event. To determine the optimum location of these protection devices,...
