Abstract[English]
Bushing and a Method for Monitoring of the Bushing The present invention relates to a high-voltage DC bushing arrangement (20, 31) comprising a test tap (26, 33). In accordance with the invention the high-voltage DC bushing arrangement comprises a monitoring means (27, 34) configured to inject a voltage and/or current pulse signal via the test tap (26, 33) and to detect and process a corresponding response signal. The present invention also relates to a method for operating an HVDC bushing, an HVDC transformer, and a converter arrangement comprising said bushing.[French]
La présente invention concerne un agencement de douille à courant continu à haute tension (20, 31) comprenant une prise de test (26, 33). Selon l'invention, l'agencement de douille à courant continu à haute tension comprend un moyen de surveillance (27, 34) conçu pour injecter un signal d'impulsion de tension et/ou de courant par l'intermédiaire de la prise de test (26, 33) et pour détecter et traiter un signal de réponse correspondant. La présente invention concerne également un procédé de fonctionnement d'une douille à courant continu à haute tension, d'un transformateur à courant continu à haute tension et d'un agencement de convertisseur comprenant ladite douille.
