Abstract	This study presents a technique to locate the source of faults in distribution systems, i.e. to pinpoint where the fault has occurred along the distribution system. More specifically, it localises the origin of short duration voltage variations (SDVVs) in a distribution system. Fault location (its origin) is estimated solely from the voltage waveforms during the fault. More specifically, the energies of the instantaneous symmetrical components corresponding to the voltage waveforms are used to estimate the fault location. The proposed localisation strategy considers that the signal records during a fault are captured at the feeder start node and at other nodes scattered along the distribution systems. Simulation results show the feasibility of the proposed technique to accurately localise the origin of faults in distribution systems.
