A MIS diode sensor (10) having a Pd/Cu alloy electrode (15) is sensitive to and can detect CO, H2, C2H2 and C2H4. An array (30) of MIS diode sensors (10) having varying electrode compositions can indicate a fault in an electrical transformer by the detection of at least one of the key fault gases CO, H2, C2H2 and C2H4.
Un détecteur à diodes MIS (10) possédant une électrode en alliage Pd/Cu (15) est sensible aux gaz CO, H¿2?, C¿2?H¿2? et C¿2?H¿4? et peut les détecter. Un groupe (30) de détecteurs à diodes MIS (10) possédant des compositions d'électrodes variables peut indiquer une défaillance dans un transformateur électrique lors de la détection d'au moins un des gaz-clés, CO, H¿2?, C¿2?H¿2? et C¿2?H¿4?, associés à des défaillances.
