A Statistical Study of DORT Method for Locating Soft Faults in Complex Wire Networks

Abstract : Decomposition of the time-reversal (TR) operator (DORT), a recently applied TR method to transmission lines, has proven to be effective in detecting and locating soft faults in complex wire networks. In this paper, we will propose a fault location criterion which will form a later basis for a statistical study investigating the influence of several parameters, namely, the number of testing ports and the position of the fault, on the performance of DORT technique. Notably, this would allow a closer inspection of the method's practicability for future implementation in real-life networks. Index Terms— Complex wire networks, decomposition of the time-reversal (TR) operator (DORT) method, soft fault location, statistical study.
