TRANSFORMATEURS TRIPHAS\u00c9S pour charges NON LIN\u00c9AIRES de 10kVA \u00e0 500kVA avec facteur K4, K13, K20<\/h3>\n\n\n\n

Les transformateurs TTI-K sont con\u00e7us pour supporter l’effet de surchauffe g\u00e9n\u00e9r\u00e9 par des harmoniques \u00e9lev\u00e9es et de forts courants sur le neutre.<\/h3>\n

Les transformateurs TTI-K sont con\u00e7us pour supporter l’effet de surchauffe g\u00e9n\u00e9r\u00e9 par des harmoniques \u00e9lev\u00e9es et de forts courants sur le neutre. L’indice K-factor indique la capacit\u00e9 du transformateur \u00e0 supporter les harmoniques tout en fonctionnant dans ses propres limites thermiques, gr\u00e2ce \u00e0 l’utilisation de conducteurs de taille appropri\u00e9e. La conception d’un transformateur \u00e0 facteur K doit tenir compte de la tendance \u00e0 la saturation d\u00e9coulant des charges non lin\u00e9aires et des composantes continues de la forme d’onde caus\u00e9es par les troisi\u00e8mes harmoniques. Les courants additionnels qui circulent dans ces cas dans les enroulements connect\u00e9s en triangle sont pris en compte pour garantir une dur\u00e9e de vie id\u00e9ale au transformateur. Ce serait une erreur de consid\u00e9rer un facteur de d\u00e9classement (de-rating) et d’utiliser des transformateurs standards : les conditions sp\u00e9ciales auxquelles ces produits sont soumis n\u00e9cessitent une conception sp\u00e9cifique.<\/p>\n
