Abstract :
Series faults are self-sustained arcs produced in series with the normal path of supply power. The electromagnetic transients produced by these series faults are of interest during the design and analysis of existing and forthcoming dc microgrids. This paper presents a preliminary series fault simulation model to predict the electromagnetic transients introduced by series faults. Experimental results are compared with simulation results. The simulation results show the random nature of the arc, quenching attempts, arc energy consumption, and the influence of inductive loads.
