Abstract:
(EN) In the field of electrical power systems there is provided a method of supervising the operation of a plurality of current transformers that are arranged in respective current transformer groups (24, 26, 28, 30, 32, 34, 36; 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108) within differing protection zones (14, 6, 18; 74, 76, 78) of a multi-phase electrical power system (12; 72). The method of supervising comprises the steps of: (a) identifying a faulty protection zone (14, 16, 18; 74, 76, 78) within the electrical power system (12; 72); (b) identifying a faulty current transformer group (24, 26, 28, 30, 32, 34, 36; 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108) within the faulty protection zone (14, 16, 18; 74, 76, 78); and (c) identifying one or more faulty phases (A, B, C) within the faulty current transformer group (24, 26, 28, 30, 32, 34, 36; 86, 88, 90, 92, 94, 96, 98, 00, 102, 104, 106, 108) within the faulty protection zone (14, 16, 18; 74, 76, 78).
(FR) Dans le domaine des systèmes d'alimentation électrique, l'invention concerne un procédé de supervision du fonctionnement d'une pluralité de transformateurs de courant qui sont agencés dans des groupes de transformateurs de courant respectifs (24, 26, 28, 30, 32, 34, 36; 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108) dans différentes zones de protection (14, 6, 18; 74, 76, 78) d'un système d'alimentation électrique multiphasé (12; 72). Le procédé de supervision comprend les étapes de : (a) identification d'une zone de protection défectueuse (14, 16, 18; 74, 76, 78) dans le système d'alimentation électrique (12; 72); (b) identification d'un groupe de transformateurs de courant défectueux (24, 26, 28, 30, 32, 34, 36; 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108) dans la zone de protection défectueuse (14, 16, 18; 74, 76, 78); et (c) identification d'une ou plusieurs phases défectueuses (A, B, C) dans le groupe de transformateurs de courant défectueux (24, 26, 28, 30, 32, 34, 36; 86, 88, 90, 92, 94, 96, 98, 00, 102, 104, 106, 108) dans la zone de protection défectueuse (14, 16, 18; 74, 76, 78).
