Abstract : Time reversal (TR) has been recently adapted with success to locate faults in power grids, thanks to its location accuracy and robustness against parameters uncertainties. FasTR algorithm, a post-processing approach based on the tenets of TR, has shown promising results in locating disturbances along transmission line networks. This paper presents the outcome of tests performed on a 2.6 km energized three-phase 20 kV buried pilot network. The tests involve single-phase-to-ground fault occurrences manually triggered, and a 3-month real-time continuous monitoring while the network is in normal operation. The fault location task is performed by a system composed four components: distributed high-speed measurement devices, accurate time synchronization, a communication tool between sensors and the FasTR post-processing algorithm. The obtained results demonstrated the capacity of an on-the-shelf portable system to make an on-line accurate detection of transient faults in a complex network.
