This invention relates to a method and system for locating line faults in a medium voltage network (3). Heretofore, the known methods and systems provided relatively limited resolution of fault location. Typically, the fault location information was limited to a distance from the substation (5). In complex medium voltage networks with branching, these systems and methods are not ideal as faults could potentially be in a number of different locations, spread out over a large area. According to the present invention, line mounted sensors (23(a)-23(I) are positioned both upstream and downstream of each of the branch points (11 (a)-11 (e), 29(a)-29(b) and this enables a more accurate determination of the location of the fault in the medium voltage net-work. Furthermore, artificial neural networks are employed to improve detection and location of faults in the medium voltage net-work. |
