This paper presents a new smarter settings-free numerical algorithm for fault location on transmission lines. It does not require line parameters, which is a radical step forward compared to the existing approaches that require this information. Line parameters are only approximately constant; they differ with the loading and weather conditions. Thus, an approach which does not require them would be more robust, accurate and flexible than those approaches that do require line parameter information to determine the location to the fault. This is essential for the fast and secure elimination of faults on transmission lines and leads to a significant improvement in the quality of the energy supply. The new algorithm also does not require synchronously sampled data at the line terminals. The paper presents the results of the initial algorithm testing through the use of ATP-EMTP simulations.
