Grounding fault location method of overhead line based on dual-axis magnetic field trajectory

HIGHLIGHTS

  • who: Xiaowei Wang from the (UNIVERSITY) have published the article: Grounding fault location method of overhead line based on dual-axis magnetic field trajectory, in the Journal: (JOURNAL)
  • what: In this paper, the sine function expressions of the x-axis and y-axis magnetic_fields are obtained by least squares fitting, and the difference of characteristic quantities between the dual-axis magnetic_field synthetic trajectories upstream and downstream of the fault point is analyzed.
  • how: Taking the three structural features (major axis minor axis and inclination angle) of the Lissajous figure as the basis for . . .
