    DC arc is the most common fault phenomenon in PV power station. Arcs will occur due to contact dropout, device aging, insulation rupture, and poor grounding. Moreover, the harm of DC arc is far greater than that of AC arc, because there is no zero-crossing point in DC arc, once it occurs, it will continue to burn, it is difficult to extinguish, and it is very easy to cause fire accidents.
