Conductor abruption, Low voltage line, Mechanical stressing., Fire start


In this paper, an investigation of a real event, in which a fire was started due to a low voltage line aluminum conductor being abrupted, is undertaken. The conductor was asymmetrically dented at the abruption point. From the performed calculations, it can be concluded that an abruption cannot be caused by sparking. On the other hand, an abruption can be caused by mechanical stress by shot pellets from a hunting rifle.
