In this paper two approaches are proposed based on Discrete Wavelet Transform (DWT) and traveling wave to locate the fault of the three phase transmission line. The exact fault position is determined according to the instances in time when the fault waves arrive at each locator location and wave speed calculated on the basis of the proposed algorithms. To achieve actual data, synchronized sampling is needed which can be made possible by precise time receivers based on Global Positioning System (GPS) time reference. All the possible fault types are generated using the ATP-EMTP and results using the two methods are discussed. Extensive simulation studies indicate that the proposed approaches are reliable for rapid and correct identification of various fault cases.
