Abstract: Unevenly abnormalities may appear on High Voltage transmission line, consequently power interruptions are taken place in distributed loads. Classification of faults is highly essential to design appropriate protective scheme at terminals of the transmission line. Faulty signals can be process through 2D or 3D Analysis .But in present paper has been analysed 2 dimensional analysis. Faulty conditions of an interconnected power system network (IEEE-9 Bus) are captured and sampled for a specific interval of time, and which are analysed by wavelet morphology to discriminate the faults at each terminal of the transmission line. This paper presents an innovative approach for the detection of fault, based on Morphological wavelet transform and Daubechies – Eight (Db-8) wavelet has been selected as structuring element for transformation of three phase currents on transmission lines, A standard IEEE 9-bus system has been simulated for different types of faults and which are process through Morphological transformation for identification of fault in a very short time period.
