Abstract:


During the last few decades, problems arising from faults affecting cable networks has became an issue of major concern in both industry and research. Consequently, vast efforts and enormous capitals have been dedicated in the domain of research and development for projects related to the detection and location of faults in wire networks. Although, reflectometrybased methods have been the standard choice for fault-detection techniques especially when dealing with simple networks and relatively hard faults, their results can be of more difficult interpretation when soft faults are addressed. Although, time reversal based methods showed a quantum leap towards solving this problem, baselining, a natural fitting approach formed an important basis towards the proper application of both methods. In this paper, we will verify that a soft fault’s signature can be easily masked by normal impedance variation in the environment of the cable. Consequently, the practical implementation of these methods to test real life networks is a critical challenge.
