Abstract
Fault location on a non-homogeneous electric power line that includes a plurality of sections by determining a section in which negative-sequence voltage magnitude profiles calculated from each terminal of the power line intersect. The fault location may determine the faulted section and determine the location of the fault within the faulted section. To determine the fault location, the negative-sequence voltage magnitude profiles may be calculated from measurements taken at each terminal of the power line and compared to determine a point where the profiles intersect. The profiles may be calculated using power line properties and measurements from each terminal.
