Fault location in electric power delivery systems |
摘要 |
Accurately calculating location of a phase-to-phase fault even on a branched, non-homogenous, radial electric power distribution system. The calculation includes determining a calculated reactance to the fault without using positive-sequence current measurements, and uses the line parameters to determine locations on the system that match the calculated reactance to the fault. The calculation may further include a determination of faulted phase and eliminate fault location possibilities based on absence of the faulted phase at those locations.
