Methodes et outils d'aide au diagnostic et à la maintenance des tableaux électriques généraux par le suivi des grandeurs physiques caractéristiques et de leur fonctionnement

Abstract : The switchboard is a key element of any electrical installation. It incorporates devices designed to distribute electrical power and protect circuits and people. This PhD work deals with an entire system of monitoring and diagnosis of Low Voltage (LV) switchboards based on the measurements of temperatures, and currents. This system meets the needs to prevent the breakdowns of LV switchboards, which, although rare, can involve huge financial and human loss. The thermal measurements are done by wireless thermal sensor. The measured data are transmitted via internet and collected in a server, to be centrally processed. This centralized data processing includes a local detection of failures and a global diagnosis which leads to some maintenance recommendations. This work is focused on, the detection stage, and the global diagnosis. Some results based on experimental data and expertise's information are presented to validate the feasibility of the methods implemented.
