<p>The monitoring method is applied to the switching isolators (S11,S12) of one bay of a substation having a set of distribution busbars (B1,B2) connected to at least three circuits comprising input and output bays and a busbar coupling bay. When a bay is transferred under load and its computer (C1) detects closure of its isolators, a message is sent to other computers (C2-C4) which record the value and direction of current in their own bays. When opening is detected of the isolator (S11) of the line to the busbar (B1) whose distribution is transferred, the foregoing data are memorised and the square of the interrupted current is computed.</p> |
