AUTOTRANSFORMATEURS TRIPHAS\u00c9S de 1 \u00e0 500 kVA<\/h3>\n

Enroulements en CUIVRE \u00e9lectrolytique.<\/em><\/strong><\/p>\n

Enroulement unique avec prise interm\u00e9diaire<\/u><\/em><\/strong><\/p>\n

L’autotransformateur poss\u00e8de un seul enroulement qui fait office de primaire et de secondaire, par cons\u00e9quent il n’y a pas d’isolement galvanique entre l’entr\u00e9e et la sortie, mais une continuit\u00e9 \u00e9lectrique.<\/p>\n

Les autotransformateurs sont des machines \u00e9conomiquement avantageuses d’autant plus que le rapport entre la tension minimale et maximale se rapproche de 1 ; dans le calcul de la rentabilit\u00e9, il faut tenir compte du rendement \u00e9lev\u00e9 et des faibles pertes en service par rapport \u00e0 un transformateur de s\u00e9paration de puissance \u00e9gale.<\/p>\n\n\n\n
