The subject of the article is the analysis of the relation between electrical phenomena in PV systems and the fire risk related to ensuring appropriate fault detection by the electrical protection system.

Can a PV system cause a DC arc flash?

During the course of fire on a building with a PV system, DC cable insulation can melt and cause a DC arc flash. The same may occur if a PV system is disconnected incorrectly. DC arcs are not only an additional life safety threat to firefighters, but also an ignition source, which will be discussed later in more detail.
