Les avaries de transformateurs dans l'industrie de l'énergie sont responsables de 50% des pertes d'exploitation - Allianz Group. Des interruptions non planifiées peuvent affecter sévèrement la production, la rentabilité et les relations client.
Grâce à la maintenance préventive vous pouvez réduire ces risques et augmenter la couverture des potentiels dommages par votre assurance en cas d’incident.
Réalisez une analyse d'huile de votre transformateur pour renforcer votre approche de prévention des avaries.
L'analyse de l'huile diélectrique permet de détecter les premiers signes de dysfonctionnement ou de vieillissement de votre transformateur, avant qu'ils ne deviennent problématiques. En anticipant ces défauts naissants, vous pourrez planifier des opérations de maintenance spécifiques et éviter les pertes d'exploitation dues à des arrêts imprévus.
Les analyses d'huile sont une solution préventive économique pour détecter les défauts avant qu'ils ne deviennent coûteux.
Par anticipation, évitez les coûts imprévus et préservez la rentabilité de votre entreprise.
En fonction de la puissance et de l'âge du transformateur, les assureurs exigent que des analyses soient réalisées dès sa mise en service et durant son exploitation. Un accent est mis sur le référentiel APSAD D91 pour prévenir les dégradations et interruptions de production en détectant les anomalies dès leur apparition.
Grâce aux analyses d’huile de transformateur, assurez votre couverture en cas de sinistre.
Les analyses d'huile offrent un diagnostic exhaustif de l’état de santé de votre transformateur. Elles établissent un point initial de référence ainsi qu'un cadre de comparaison pour un suivi ultérieur.
(tout type d’appareil)
Chromatographie : l’analyse des gaz dissous d’un transformateur contribue à la détection des défauts thermiques et/ou électriques liés aux parties actives
L’analyse de la rigidité diélectrique de l’huile, teneur en eau, et indice d'acidité pour évaluer les capacités isolantes et caloportrices du fluide, ainsi que sa qualité.
Analyse des dérivés furaniques et du méthanol pour évaluer l'état des papiers isolants et estimer la durée de vie résiduelle du transformateur.
La recherche et les dosages des PCB pour vérifier la conformité avec la réglementation.
Plusieurs éléments peuvent amener à l’apparition d’eau au sein du transformateur :
Les défauts thermiques ou électriques, détectables par la présence de gaz dissous, peuvent avoir des conséquences graves, telles que l'explosion ou l'arrêt du transformateur.
Évitez 60% des avaries majeures en combinant une analyse des gaz dissous de votre transformateur avec les données d’un monitoring embarqué (CIGRE TB# 630).
La dégradation des papiers des transformateurs en fin de vie est liée à plusieurs facteurs, tels que l'humidité, l'acidité, la température de l'huile, l'oxygène, les surcharges et divers défauts tels que la pyrolyse, les décharges partielles et les points chauds.
Les dérivés furaniques et le méthanol/éthanol sont utilisés pour évaluer le vieillissement des isolants cellulosiques.
Les dérivés furaniques (DF) sont utiles pour estimer l'état de l'isolation cellulosique dans la seconde moitié de la vie des équipements utilisant du papier Kraft.
Le méthanol (MeOH) et l'éthanol (EtOH) permettent de détecter la dégradation précoce des papiers au début de leur cycle. Le méthanol rend possible le ciblage de la dégradation des papiers nouvelle génération, souvent utilisés avec le papier Kraft, permettant ainsi de distinguer un vieillissement normal ou anormal (pyrolyse).
Les polychlorobiphényles (PCB) ont entraîné d'importantes répercussions environnementales au fil du temps. En raison de leur faible biodégradabilité, ces substances se sont accumulées dans divers éléments de la chaîne alimentaire et dans l'environnement global, incluant sol, air, eau, sédiments, plantes, animaux, et même l'Homme.
La réglementation concernant la concentration des PCB dans les appareils varie selon les normes établies par chaque pays.
Référence : Directive de l’Union Européenne.
Pour votre conformité, il est recommandé de procéder à une analyse des PCB sur votre transformateur, afin de déterminer si celui-ci est contaminé.
La fréquence des analyses d'huile de transformateur dépend de l'état de santé de l'équipement.
En l'absence de défaut apparent, le Laboratoire OKSMAN SERAPHIN conseille une analyse annuelle. Il convient toutefois de noter que chaque analyse annuelle peut différer selon les besoins de recherche.
En cas de signe anormal ou de dysfonctionnement constaté, la fréquence d’analyse de l’huile de votre transformateur à risque, peut être augmentée sur recommandation des experts.
L‘analyse d'huile de transformateur n'est généralement pas soumise à une réglementation spécifique.
CEPENDANT : des directives concernant la gestion des polychlorobiphényles (PCB) dans les transformateurs existent dans de nombreux pays.
En France, il est impératif de détecter la présence de PCB dans les transformateurs, conformément au code de l'environnement français (Articles R-543-17 à R-543-41). Cette détection est réalisée par le biais d'une analyse d'huile.
Aux États-Unis, une réglementation (40 CFR Part 761) sur la gestion des PCB est également en vigueur, établissant des normes pour leur utilisation, leur manipulation, leur stockage, leur transport et leur élimination.
D'autres pays ont mis en place des lois et normes équivalentes pour contrôler et restreindre l'utilisation des PCB dans les transformateurs, ainsi que pour garantir leur élimination, minimisant ainsi les risques pour la santé et l'environnement.
De plus, les compagnies d'assurance exigent des preuves de maintenance régulière, y compris des analyses d'huile, pour garantir la couverture du transformateur cas d'incident.
Pour réaliser un prélèvement d'huile sur votre transformateur, il important que l‘équipement soit hors tension et que les opérateurs possèdent un titre d'habilitation électrique adapté au travail à effectuer et au niveau de tension concerné.
Le prélèvement d'huile se fait généralement à deux points spécifiques du transformateur : la vanne bas de cuve ou la vanne haut de cuve. Notez que cette opération requiert une compétence particulière, qui peut être acquise grâce à une formation au prélèvement d‘huile de transformateur.
Pour garantir la sécurité, il est recommandé d'être accompagné lors du prélèvement d'huile.
Après avoir effectué entre quatre et cinq prélèvements d'huile sur votre transformateur de distribution, il est généralement recommandé de vérifier le niveau d'huile et de remettre de l’huile. Cela permet d'éviter un risque de déclenchement du transformateur électrique en raison d'un niveau d'huile insuffisant.
Assurez-vous de suivre les recommandations du fabricant et les spécifications techniques du transformateur pour déterminer le niveau optimal d'huile et effectuer correctement le remplissage si nécessaire.
