Accurate fault location of high voltage overhead transmission lines is one of the effective ways to ensure the safe and stable operation of power system. To this end, the article introduces the development history and research status in this area both at home and abroad. According to different principles of each ranging algorithm, the existing ranging algorithms are divided into three categories: traveling wave ranging, single-ended ranging and double-ended ranging, and then the theoretical basis and application of various algorithms Conditions were analyzed, compared and discussed, and on this basis, summed up the advantages of each ranging algorithm and the existing problems, and pointed out the scope and application of each ranging algorithm limits. Finally, the prospect and prospect of fault location in HV overhead transmission lines are discussed
