INFLUENCE OF COPPER WIRES IN ELECTRIC NETWORKS ON FIRE RISKS: LOCAL X-RAY SPECTROMETRY ANALYSIS

Abstract

The results of researches on the change of oxygen content in the copper wires of electric networks in conditions of different current intensities and different terms of cooling are presented. The results are obtained on the basis of local x-ray spectrometry analysis using the principle of spectrums’ individualities. The main features of copper wires’ structure changes at different temperature conditions are determined. The efficiency of using this method with the aim of fire origins establishment is shown.
