Overview

The transmission line is an important part for the electrical network, but since it needs to cross long distances, it is easy to have faults. Sometimes, it is very difficult to patrol the lines because of the weather and the field condition, so it is vital to have an equipment capable to locate the fault with the accuracy of one tower. It is also important to have a system capable of locating recurrent intermittent faults, like swaying trees, with high impedance faults (up to several hundreds of Ohm), or breaking.

The travelling wave fault locator determines the distance to fault by measuring the time for the surge to travel from the fault to the substation bus. The system provides a number of different fault location methods; the so-called D method is the one used

Type D Method time tags the arrival of the fault generated surges (current and/or voltage) at the two time synchronized locations, at both ends of the line. The fault distance is determined measuring the difference of the arrival times, by the following

Key capabilities
