| Summary: | Paper show methodic of determine values of «resonance» frequencies on overhead power lines in single-phase ground fault mode. There are introduction of Additional power line in the mathematical model Consideration of Availability of working feeders Connected to the common buses of the power center together with the emergency line. Power grid has influence on the value of the «resonance» frequency in the lowering of the level of value in comparing of working of single line. The value of “resonance” frequency depend from the level of short circuit on the substation buses |
