Fault location in power distribution systems is very important because of power service continuity requirements, mainly imposed by current electricity market quality standards. A fault location approach is adopted in this paper using current waveforms as measured at electricity substations, knowledge of protection-device settings and ANFIS networks. Good results were obtained from tests carried out in a prototype power distribution system to locate where faults were occurring. These results revealed variation in fault-locator precision due to using different current signal characteristics or descriptors. An error lower than 1% was obtained in the best case. Two more alternatives are also presented where errors were lower than 4%; such results validate the approach presented here.
