Abstract: Selected problems occurring in distance protection systems during earth faults in high voltage overhead cable lines (HV) were analyzed.
The Alternative Transients Program (ATP) environment was used to simulate and model the phenomena. The influence of such factors as: fault location, rrangement of HV cables in the excavation, configuration of the return conductors and the earthing resistance of the return conductors was analyzed. The obtained results make it possible to verify the criteria for detecting earth faults in HV networks.
