Abstract: Experiments were carried out to simulate the ground short circuit of single core PVC copper conductor. The changes of ground short circuit weld mark surface composition of copper wire along with the electric current increasing before and during the fire were recorded and analyzed. By linear regression analysis, the factors affecting the element content of copper wire weld mark surface was discussed. The study can provide scientific guide for fire investigation.
Key words: copper wire, ground short circuit, surface composition
