In order to realize fast phase selection when fault occurs in EHV transmission line, a scheme of faulted phase selection is proposed based on the features of faulted traveling waves and the singularity detection principle of wavelet transforms. According to the boundary conditions of fault types, the basic relationship meeting the wavelet modulus maxima of each mode component is deduced by the phase-mode transformation formula, and a simplified phase selection criterion is obtained and improved. Simulation results show that this phase selection scheme can detect faulted phase accurately for various fault types at any conditions involving different fault inception angle, fault resistance and fault position.
