Transmission lines safeguard against exposed fault is the most critical task in the protection of power system. The purpose of a protective relaying is to identify the abnormal signals representing faults on a power transmission system. So fault classification is necessary for reliable and high speed protective relaying. This paper uses fuzzy logic technique for fault classification and this study describes a new approach to distinctly identify and classify ground and phase faults by using two separate fuzzy classifiers. Samples of post fault currents from all three phases at one end of the transmission system are being used to classify the nature of the faults. To demonstrate the effectiveness of this method, simulations considering various operating conditions have been performed on MATLAB. The simulation studies of the proposed technique indicate that the accuracy in fault classification increases because of two fuzzy classifiers is used for fault analysis.
