| 摘要 |
The invention relates to a method and device for monitoring an electrical network, comprising: means (51a-52b) for detecting electrical signals (S1a, S1b) and complementary signals (S2a, S2b) generated in the electrical network (3), the complementary signals (S2a, S2b) having a different physical nature than that of the electrical signals (S1a, S1b); a means (7) for processing said electrical signals in order to define a first time reference (t1) representative of a time of detection of the electrical signals transmitted during a fault event (E1, E2) that occurred in the electrical network; a means (7) for processing said complementary signals in order to define a second time reference (t2) representative of a time of detection of the complementary signals transmitted during said fault event that occurred in the electrical network; and a processing means for spatially locating said fault event in the electrical network in accordance with said first and second time references (t1, t2). |
