[0002] The stable operation of the power system is crucial to all aspects of modern society. In the power distribution network, the 10kV distribution line is an important link between the high-voltage transmission network and the user end.

However, due to the influence of various factors such as the natural environment, equipment aging, external force damage, etc., various faults such as short circuit, grounding, overload, etc. are inevitable in the operation of the 10kV distribution line.
