Resumo:
The fault location procedure consists in estimate the location of the disturbance by
treating the voltage and/or current signals monitored at the transmission line terminals.
According to the processing performed, the means of locating the fault may be
classified as fundamental frequency or traveling wave based techniques, making some
applications preferable to others due to the ability of being immune to certain factors
present in the electric power system as the dynamic behavior of the coupling capacitor
voltage transformers, the characteristics of the short-circuits and the sampling rate. In
this way, the analysis proposed here looks for the factors that influence the performance
of fault location methods, two of them based on fundamental components and one based
on traveling wave theory. Therefore, a comparison is made between the performance of
the evaluated methods, highlighting the main factors capable of influencing a fault
location process in a precise way.
