A Travelling predicated fault locator approach is implemented in this paper for the teed transmission network. The work is similar to the fault location for teed circuits for unsynchronized measurements in [12]. Advantage of S-transform is more effective then wavelet transform. The stock well transforms (S-Transform) technique is utilized for the extraction of high-frequency fault transients in order to confine the peregrinate time of the transients along the monitored lines between the fault points and relays. The fault location is resolute by taking time distinction between the advent of the rearward and forward travelling waves. The algorithm gives precise results for the three-terminal lines under different fault conditions. The performance of the algorithm is tested in a MATLAB environment.
