Highlights
Minimizing supply interruption times is a main goal for distribution system operators (DSO)
PSCAD has been chosen for this reflectometry study, because it is a simulation environment that allows the creation of networks based on real wires using a transmission line model
The proposed fault location method relies on the electric waveforms recorded at the secondary electrical substation, at the same point where the injector generates the signal that travels through the lines of the network
Summary
Minimizing supply interruption times is a main goal for distribution system operators (DSO). Reflectometry is the most accurate method for fault location This technique consists in studying the reflections of electrical signals when they travel through the network. Due to this feature the propagation characteristics do depend on the wire insulator properties and on the environment surrounding the LV line [9], [10]. Possible solutions are formulated, whose implementation are the subject of ongoing research conducted by the authors
