wireless distributed system and method for classifying and locating faults in an electrical distribution network underground

摘要

The invention relates to a distributed wireless system and method for the classification and localisation of failures in an underground electrical distribution network, comprising sensor devices (3), forming a network of wireless sensors (2), distributed in the underground electrical distribution network (1) and coupled to conductors (7) of the network (1) such that all the sections of conductors between bifurcations have an associated sensor device (3). The sensor devices (3) comprise means for measuring the current (34) that circulates via the conductor (7), being synchronised with one another and configured to identify the type of failure occurring and the localisation thereof by means of the interchange of messages, between the different sensor devices (3), with information relating to the synchronised current measurements and by means of the analysis of the phasor information of said synchronised current measurements, taking into consideration the topology of the network.
