Abstract	Six-phase transmission is an optimal solution for increasing the power transmission capability of overhead power transmission lines over existing rights-of-way. This new technology, however, requires a new protection techniques. Therefore, this paper introduces a new technique based on wavelet transform for accurate fault location of six-phase transmission lines. The technique utilizes a wavelet to capture the fault induced high frequency transient currents superimposed on the power frequency currents in a modal domain. The fault location is determined based on the relative arrival times of these high frequency transient signals at the relaying point. The introduced technique is tested and validated through simulation studies. The results show that the technique is accurate in fault location irrespective of the fault type, fault inception angle, and fault resistance. Moreover, it is insensitive to the line terminals and transposition.
