- Abstract
This paper proposes an analysis tool using the R-X axis of a faulted system to solve the fault location problem in power systems. The proposed approach allows locating all types of faults including high impedance ones and faults on overload systems. Methodologically, the apparent impedance R-X axis of faulted phases is analyzed and the fault is located from distance curves, previously obtained from the power system, by using two-dimensional interpolation. As results, tests of a reference system with four types of faults and different fault resistances located on different places on the system are presented. Errors are kept lower than 3% for single phase faults and fault resistances up to 1000[Ω].
