The present invention is directed to a method and a system for fault detection analysis in a power device which is operatively associated with a differential protection unit. The power device has one input side and one output side through which an input current and an output current flows into and out from it, respectively. Signals representative of the input and output currents are processed in order to verify if an occurring fault is external to the power device. Under a condition of an external fault, the differential protection unit is disabled for a determined interval of time.
L'invention concerne un procédé et un système d'analyse de détection de défaut dans un dispositif électrique associé à une unité de protection différentielle. Ce dispositif électrique possède un côté entrée et un côté sortie entre lesquels s'écoulent un courant d'entrée et un courant de sortie respectifs. Des signaux représentant ces courants d'entrée et de sortie sont traités afin de vérifier si l'apparition d'un défaut est externe à ce dispositif électrique. Dans le cas de défaut externe, l'unité de protection différentielle est mise hors service pendant une durée déterminée.
