Keywords: PRBS diagnostic CCR method, pseudorandom binary sequence (PR

Abstract: A novel pulse echo test methodology,using pseudorandom binary sequence(PRBS) excitation, is presented in this paper as an alternative to Time Domain Reflectometry(TDR) for transmission line fault location and identification.The essential feature of this scheme is the cross correlation(CCR) of the fault response echo with the PRBS test input stimulus input which results in a unique signature for identification of the fault type, if any,or load termination present as well as its distance from the point of test stimulus injection.In this paper a high frequency co-axial transmission line model is presented for transmission line behavioural simulation with PRBS stimulus injection under known load terminations to mimic fault conditions encountered in practice for proof of concept.Simulation results,for known resistive fault terminations,with measured CCR response demonstrate the effectiveness of the PRBS test method in fault type identification and location.
