			<p><i>Le diagnostic post-avarie sur le Transformer a montré des <b>signes d’arcs électriques</b> sur les contacts sélecteur de prises. L’avarie a été <b>causée par la formation de sulfures de Cuivre/Ag</b>,  tels que  CuS, Cu<sub>2</sub>S, Ag<sub>2</sub>S, etc. En effet, «</i><i>à relativement haute température, les molécules d’huile contenant du soufre peuvent se décomposer et réagissent avec la surface métallique pour former des sulfures métalliques</i>”  (IEC 60422 éd. 4 – 2013 Art 5,17). Ce mécanisme à eu lieu lors du processus de régénération de l’huile à l’étape de réactivation de la colonne de terres par la combustion non contrôlée (&gt; 370 ° C). Les composés sulfurés présents naturellement dans l’huile, ainsi que les additifs (Dibenzothiophene – DBTP, etc) (DBDS, etc), sont alors décomposés en **<b>sous-produits de dégradation du soufre</b>. Autres cas typiques : National Grid Ref (UK), ABB (Suède), 2010 Conférence Doble (USA)</p>
