Experimental and Theoretical Study of Arc Beads from Short Circuits at Fire Scenes

Résumé fourni par la source

In this study, we investigate the phenomenon where momentarily melted copper is scattered from the power source side to the load side during a short-circuit in electrical wiring, caused by arc sparking at the fault. This results in different short-circuit shapes on the power source side compared to the load side. Additionally, we theoretically analyze physical phenomena such as the Lorentz force acting on the electric wire during a short-circuit. By sharing these experimental and theoretical findings, we aim to better understand the mechanism of short-circuit formation and utilize this knowledge to pinpoint specific ignition points in fire investigation contexts.
