The data published by the national power grid in recent years shows that the underground cable in the city is in a failure high-occurrence period, so that the deep research on the fault location, line selection and classification of the underground cable has extremely important practical significance on the safe and stable development of the city economy. At present, most fault positioning, line selection and classification methods applied in the power distribution network are fault off-line diagnosis, so that fault prediction is difficult to be carried out on early intermittent faults, and if any intermittent fault develops, permanent faults are likely to be caused, and great threat is brought to lives and properties of a large number of users. And the high-voltage single-core cable is more and more widely applied in urban power supply systems, and under abnormal conditions, the metal sheath of the single-core cable may form larger circulation and heat due to the existence of induced voltage, so that the main insulation of the cable is threatened, and even an accident is caused to influence the safe operation of a power system. Therefore, the metal sheath circulating current of the single-core cable can be used as one of the criteria for judging whether the cable normally runs. Meanwhile, when the cable breaks down, the fault traveling wave signal is an important condition for positioning the cable fault. Therefore, the abnormal condition of the cable can be effectively analyzed by combining the cable sheath circulating current and the fault traveling wave analysis, and the method has important significance for the safe operation of the power grid.
