Diagnostic des Transformateurs de Puissance par l'Analyse de la Réponse Fréquentielle (FRA)

Abstract

This work is a study and modeling of transformers windings for its diagnosis. And this winding discredited in 10 hard disk; each disc contains 20 rounds of 200 mm average diameter. After having validated the model adopted by three different approaches approached, we operated for a diagnostic study of the transformer winding. For study the various failures of the coil with the frequency analysis technique. Keyword: transformer, Diagnosis, frequency analysis
