Research on the Characteristics of Leakage Current Changes in Tree Line Faults of 10Kv Distribution Lines

There are numerous cases of forest fires caused by tree line faults in distribution lines, and it is of great significance to study the characteristic signals when tree line faults occur to prevent mountain fire accidents. In this paper, through theoretical analyses and the construction of real experimental platform, we studied the change rule of leakage current when single-phase tree line fault occurs in different trees. Through the single-phase tree line fault experiment, the relationship between leakage current and tree species, capacitive current to ground and water content when different trees touch the line is studied. The results of the study show that: the occurrence of single-phase tree line fault leakage current for the first time to reach the maximum value of time and tree species, the first time to reach the maximum value of the water content of trees and ground capacitance related.
