In this paper, a new approach to transmission lines' parameter measurement is proposed. It adopts GPS as synchronizing time of phasor measurement unit, and obtains three sequence lines' parameters by computing voltage and current phasors. Compared with the traditional methods, this method is more convenient and no more require line tripped.
