Résumé:
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.
