Abstract:
1. A method for locating an event occurring along a phase line on a section of an electrical energy transmission line, the phase line having n conductors electrically insulated one from another and short-circuited between themselves at two extremities of the section, the method comprising the steps of: a) monitoring a parameter on one of the n conductors of the phase line, at one of the extremities of the section without a ground reference, said parameter being representative of current operational conditions of the phase line and having a known propagation speed in the conductor; b) generating an event detection signal at the extremity of the section each time the parameter has a value exceeding a threshold, and storing a reception time when the detection signal is generated; c) transmitting a signal representative of the geographic location of the extremity of the section; and d) geographically locating the event along the section once two consecutive detection signals are generated from the signal representative of the geographic location of step c), and from the reception times associated with two consecutive detection signals.
