The invention concerns a method for deicing energized electrical transmission lines by means of an apparatus capable of producing an angular offset between its terminals. The method consists in: selecting segments (4, 6) of electrical transmission lines to de deiced, connecting the segments (4, 6) so as to form a loop, connecting the apparatus in series with the segments (4, 6) of the loop to be deiced. In the case of an apparatus with adjustable angular offset, it consists in switching on the apparatus and adjusting the angular offset to impose an increase of current flowing in at least one of the segments (4, 6) as the case may be. In the case of a apparatus with fixed angular offset, it consists in using a switch (54) or a circuit breaker (28) so as to connect the apparatus in the loop, the apparatus and the line segments being previously selected such that the angular offset imposes the required current increase to the deicing of at least one of the segments (4, 6) of the loop.

Méthode de déglaçage de lignes électriques sous charge à l'aide d'un appareil apte à produire un décalage angulaire entre ses bornes. On choisit des segments (4, 6) de lignes électriques à déglacer. On connecte les segments (4, 6) de manière à former une boucle. On raccorde l'appareil en série avec les segments (4, 6) de la boucle à déglacer. Dans le cas d'un appareil à décalage angulaire ajustable, on met l'appareil en service et on ajuste le décalage angulaire pour imposer une augmentation de courant circulant dans au moins un des segments (4, 6) de la boucle, causant ainsi le déglaçage du ou des segments (4, 6) selon le cas. Dans le cas d'un appareil à décalage angulaire fixe, on utilise un interrupteur (54) ou un disjoncteur (28) afin de mettre l'appareil en circuit dans la boucle, l'appareil et les segments de lignes étant préalablement choisis pour que le décalage angulaire impose l'augmentation de courant nécessaire au déglaçage d'au moins un des segments (4,6) de la boucle.
