Taking a single-circuit line ground fault of a 10 kV double-circuit lines on the same tower developing into a double-circuit lines interphase ground fault and leading to line break as an example,the electrical characteristics of ground fault are analyzed theoretically.Combined with the analysis of wave recording data and on-site investigation data,the fault evolution process and causes of fault development are deduced,and suggestions are put forward from the aspects of developmental ground fault.
