A Study on the Determination of Ignition Point According to Multiple Short Circuits

The most widely used method by fire investigators to identify the ignition point and cause of an electrical fire is the “arc mapping” technique, which uses electrical factors to find the ignition point. If multiple short circuit marks are found in electrical wiring connected like a spider web, electricity does not flow to the separated load side, so the final load side is viewed as the ignition point. Arc mapping is one of the techniques that fire investigators are currently using very widely when investigating and identifying electrical fires. However, there is a tendency to abuse the arc mapping technique at all fire scenes, and many recent limitations and negative research content on the technique have been mentioned. Accordingly, our research team conducted a fire reproduction experiment assuming the occurrence of multiple short circuits to more clearly and specifically derive the fire cause and ignition point.
