Electrical fire ignitions: The evolution assists identifying the origin in the distribution level

Fire destroys all things, so it is not easy to identify its cause. The paper suggests a deductive approach in matching possible hypotheses on electrical ignitions. It analyzes the different evolutions that characterize the ignition in a primary electrical distribution versus to the ignition in a branch distribution. At this aim, the paper illustrates a case study of the ignition of a fire that affected two fabrics storage rooms and a transformers substation that was adjacent.
