Study about Recognizing Singularity of Fusion Mark and Mark by short circuit of cable by electrical fire

This paper, at the result for test to find singularity on identifying melting cause of short from folding by physical external force to happen in the midst of using cord, can recognize that in case of short circuit by folding of cord, there is a formal difference among characteristics which cutting part within component wire accords with part of short circuit, fusion mark of external fire heat in the condition of power authorization and fusion mark in the condition of power unauthorization, in the condition of power authorization, component wire does not have component wire and only fusion mark is recognized and in the condition of power unauthorization, only lump of fusion is recognized.
