Technology development in supplying electrical power should be in parallel with advancement of computer technologies. With these advancements in technologies, reliable and quality of energy to customers can be enhanced by classifying the fault types and determining the fault location precisely within few seconds. Without precise and fast fault location, power restoration plan will take longer time and surely loose customers profit and confidence towards the utilities. This paper presents an intelligent technique for locating fault points in term of their geometrical coordinates in a practical power distribution system. The proposed technique implements an ANFIS approach by using parallel ANFIS blocks for each selected fault types and fault points. Then, the designed ANFIS is presented as a GUI tool to display fault points in X-Y coordinates whenever the post-fault three-phase root-mean-square RMS currents is given as the input. The technique produces satisfactory results with an average percentage error of 1.193E-5% and 0.0214% for X and Y coordinates prediction, respectively. The proposed technique is validated through simulations using the commercial software package PSS-ADEPT. The results show that designed parallel ANFIS approach is fast and effective in determining precise fault location in a practical distribution system.
