| Summary: | Paper show methodic of determine of place of single-phase ground fault with intermittent arc on the overhead power line. The informative signs of single-phase ground fault place are determine by values of voltage of the «resonance» frequencies of zero sequence with measuringby sensors install on the overhead power line and by values of voltage of direct and inverse sequences measuring by sensors install on 0.4 kV side of consumers substations. Place of fault can be calculate by determined values of the voltages of the "resonant" harmonics, measured on consumers substations. Calculation accuracy is limited by parts of power line between consumers substations. |
