A Possibility of Reducing the Induced Voltage Within a Repair Area1

详细

The electromagnetic effect of a live high-voltage line on a disconnected line is analyzed. It is shown by calculation that the zero-potential point of the disabled conductor can be shifted to the repair area by changing the grounding resistance at the substations. To this end, adjustable resistors placed between the disabled conductor and the grounding devices at the substations can be used. The possibility of automating this process is examined.
