High Energy Arcing Fault Events (HEAF) Project

WebAn arc fault is dangerous and harmful for the PV array because conductors may be melted from the generated intense heat and also arc fault leads to fire hazards. Compared to an AC system, an arc in the DC system can lead to a sustained arc because the current through the DC arc is not periodic and also does not have zero-crossing [50].
