The calculation of short-circuit currents in primary feeders is highly influenced by parameters which may have a considerable degree of uncertainty in their assessment. Thus, there is a reasonable possibility that the results of short-circuit calculated be inaccurate, compromising the adjustment of the protection system of primary feeders. Thereby, this paper presents a new methodology for locating-faults on primary feeders that aims equalize these issues, providing basically proper treatment to the parameters that can accommodate uncertainties. This methodology was implemented in a software which presented great performance in localizing faults in the electric distribution network. (4 pages)
