The power systems are exposed to various types of faults that can cause disturbances. A fast restoration of faulted elements can reduce the possibility of a major disturbance, but it is necessary to determine the location of the fault. This paper describes a method for the fault location diagnosis combining information of synchronized phasor measurements and the principal component analysis as statistical analysis of the data. Results are presented of the location of failure diagnosis for various cases using the IEEE 39 bus system.
