Summary:Transmission utility companies continuously strive for high availability of their lines. When a line is off service following a permanent fault, a significant amount of the time during the restore the line can be attributed to locating the point of the fault. This paper shows how this time can be significantly reduced using highly accurate traveling wave (TW) fault locators. It describes location results of several faults in three separated transmissions lines. The collected data are compared to those obtained by considering one- and two-end impedance location algorithms for the same faults. It also highlights the unique characteristics of Reason fault locators to overcome common problems of other TW solutions existing in the market.
