Abstract

La présente invention concerne un procédé de saisie de grandeurs électriques d'un réseau de courant alternatif triphasé comportant une première, une deuxième et une troisième phase. Ce procédé comporte plusieurs étapes consistant à mesurer, à un premier instant, une valeur de tension de la première, de la deuxième et de la troisième phase par rapport à un conducteur neutre, à transformer ensuite les trois valeurs de tension du premier instant en coordonnées polaires correspondant à une amplitude de tension et à un angle de phase, à répéter alors les étapes de mesure et de transformation pour au moins un autre instant, et enfin, à utiliser les valeurs de tensions transformées en coordonnées polaires pour déterminer la fréquence effective, l'amplitude de tension effective, et/ou l'angle de phase effectif de l'une des phases.
