Abstract: One of the most difficult problems in solving faulted networks involves two or more faults which occur simultaneously in power systems. Abnormal conditions in short circuit and open conductor faults been analyzed. The main objectives of multiple fault detection and diagnosis are to satisfy the power supply continuity, maintains system, stability, decrease repair times and high reliability degree. This study presents an approach for detection and diagnosis of multiple faults in transmission lines. Voltage and current measurement method is adapted in the fault detection and classification, reactance based method in the fault location for different types of fault and places were to an estimate of the distance the fault on the transmission line from the point measurement by analyzing the data available after the beginning of disturbance. All programs were written in MATLAB environment. The programs were test on IEEE-14 bus bar network. The results clarified that the voltage and current measurement method and impedance method is very effective for multiple fault detection, classification and location.
