In this research, we focus on low-voltage arc-faults in AC systems. In our previous studies, we demonstrated that arc-faults in AC systems differ from those in DC systems because in an AC system the arc itself is not a gap-jumping electrical arc between two conductors but rather an advanced glowing connection state that occurs exclusively in copper-based connections. In the present study, we improved upon our AC arc-fault generation simulation in MATLAB, matching our previous findings. The arc-fault simulation in MATLAB replicated the exact waveform exhibited in an actual AC arcfault environment. Therefore, we concluded that the phenomenon likely followed the mechanism we proposed in our previous research. We have also detected the phenomenon by using a method we devised in our previous research and refined it to match the mechanism derived from our present findings. The simulation results for our detection method revealed that to obtain the best detection accuracy, the magnetic core of the inductor/current transformer must have low coercivity and may not be saturated before the current waveform has shifted to another polarity. This detection method may yield a greater ratio of accuracy to manufacturing cost given that the main component does not include a high-frequency circuit analyzer.
