초록

Identification of the cause of electrically related fire accident may be approached either by studying accident related electric properties or by investigating power instruments at the site of the accident. In the present paper, the former approach is taken especially on investigating the consequences of excessive current induced by electric short circuiting of high power instruments which is reported as the primary cause electricity related fire accidents. In order to provide reliability of the identification method, microscopic photograph's are taken for the cross sections of the electric wires after being exposed to over current and heated by external means, respectively The results are consequently compared and analysed.
