Fault location in power transmission systems must be fast and effective, in order to provide a quick response, thereby reducing the interruption time. Currently, methods of fault location in power transmission lines are classified in four categories, namely: impedance-based methods, travelling waves methods, high frequencies methods and artificial intelligence methods. Among them, one of the most interesting is the traveling waves based, however, one aspect that can affect this method is the sampling frequency. In this way, this paper will present a study regarding the influence of the sampling frequency for traveling waves based fault detection method. Some tests and results will be presented in order to show the impact of the different sampling frequencies on the performance of the fault detection method.
