LOCALISATION OF A DEFECT ON A SECTION OF A DEAD ELECTRICAL LINE

摘要

A localisation of a defect on a section of a dead electrical line is carried out by measuring a reflection signal characterising the defect and coming from a voltage signal applied to the section. An application of the voltage signal and corresponding measures of reflection signals are simulated with a model of the section for a defect located in different areas along the section. The simulated reflection signals are compared with the measured reflection signal. A site of the defect is localised according to the area of the defect for the simulated reflection signal having a higher correlation with the second reflection signal measured.
