In this paper, a very successful performance fuzzy logic-based fault classification scheme has been realized. To achieve high accurate classification of all ten types of shunt faults from this approach, an improved technique has been presented in this work. The proposed technique is able to identify all ten types of shunt faults with high accurate performance in wide variety of system conditions. The faults that occurred in high fault resistances, high system loading level and high distances from relaying point are identified correctly as well as. To illustrate the performance of proposed improved technique a large numbers of test cases was generated. The simulation studies have been carried out using PSCAD/EMTDC and MATLAB fuzzy-logic toolbox.
