“…In [7] using the travelling wave theory of transmission lines, the wavelet transform coefficients at the two lowest scales are used to determine the fault location for fault type and line configuration. Method in [8] locates fault by combining the travelling waves methodology with the network topology to isolate the faulty link first and then locate the fault distance. The faultlocation methods described in [9] employ Wavelet Entropy and Neural Network.…”

In distribution system, the subject of fault location has been of considerable interest for a long time. The objective of this paper is to develop Cumulative approach for fault location based on statuses of Fault Indicators (FI), Circuit Breakers (CB), Fuses and Fault Impedances from distance protection devices. This approach is using mainly graph theory algorithms and Area Marking Strategy to resolve fault diagnosis problem in electric power networks. Unlike neighborhood approach where one link only affects the marking of neighbor areas, cumulative approach marks all areas down the link. In many situations, cumulative approach may out-perform neighbor approach.
