Abstract

L'invention concerne le contrôle des machines électriques. Dans l'appareil de l'invention, un dispositif 12 prélève un échantillon de liquide diélectrique d'une machine électrique 10, puis les gaz dissous dans cet échantillon sont extraits et introduits dans un appareil d'analyse chromatographique en phase gazeuse 18. Un circuit de traitement de signal 20 attaque un enregistreur de données 22 à partir du signal de sortie de l'appareil d'analyse chromatographique. Application au contrôle permanent des transformateurs de forte puissance
