группа соединения трехфазной обмотки
Угловое смещение между векторами, представляющими напряжения между нейтралью (реальной или воображаемой) и одноименными выводами двух обмоток. При этом напряжения прямой последовательности прикладывают к выводам обмотки высшего напряжения в алфавитном порядке (если они обозначены буквами) или в числовой последовательности (если они обозначены цифрами). Принято, что векторы напряжений вращаются против часовой стрелки
Примечание — Вектор обмотки высшего напряжения принят в качестве базисного; смещение вектора напряжения любой другой обмотки обычно выражают в часах, при этом время указывает вектор напряжения данной обмотки (аналогично часовой стрелке), когда вектор обмотки высшего напряжения показывает 12 ч (аналогично минутной стрелке); возрастающие числа указывают на увеличивающийся сдвиг фаз.

phase displacement
phase difference (for a transformer)
the angular difference between the phasors representing the voltages between the neutral point (real or imaginary) and the corresponding terminals of two windings, a positive-sequence voltage system being applied to the high-voltage terminals, following each other in alphabetical sequence if they are lettered, or in numerical sequence if they are numbered. The phasors are assumed to rotate in a counter-clockwise sense
[IEV number 421-10-08]FR
déphasage (pour un transformateur)
écart angulaire entre les phaseurs représentant les tensions entre le point neutre (réel ou fictif) et les bornes homologues de deux enroulements lorsqu'un système de tension direct est appliqué aux bornes de l'enroulement à haute tension dans l'ordre de séquence alphabétique de ces bornes si elles sont repérées par des lettres, ou dans leur ordre de séquence numérique si elles sont repérées par des chiffres. Les phaseurs sont supposés tourner en sens inverse des aiguilles d'une horloge
