Abstract
PURPOSE. It is very important to localize the short circuit in case of power line failure. A significant percentage of power lines damage belongs to single-phase short circuits accompanied by phase breaks. This paper proposes the methods for determining the locations on the lines in networks with a grounded neutral using instantaneous values of industrial frequency parameters. METHODS. The studies are carried out according to the programs simulating transients under short circuits accompanied by the appearance of aperiodic components in currents. RESULTS AND THEIR DISCUSSION. An algorithm is proposed for a one-way determination method of a transmission line phase break location that is based on the processing of instantaneous values of currents and voltages. An algorithm for the elimination of aperiodic components from measured currents is proposed and researched. CONCLUSIONS. The measurement time will not exceed 2.5 ms under the sampling interval of 0.5-0.625 ms. Magnetic cores of current transformers will not saturate during this time. It means that relay protection receives undistorted information and it is possible to determine the location of the power line phase break by measuring the instantaneous values of phase currents and voltages of the line section without short circuit.
