METHOD FOR PROTECTIVE GROUNDING OF AN OVERHEAD POWER LINE UNDER VOLTAGE Russian patent published in 2022 - IPC H02G1/02 

FIELD: electric power industry.

SUBSTANCE: invention relates to the field of electric power industry. According to the method on an overhead line that is energized, only the supports of the overhead line are subject to grounding. The value of the maximum touch voltage on the overhead line supports and the potential equalization zone during the work are determined. Within the potential equalization zone, metal sheets, grids are placed on the ground, portable grounding devices are installed, and they are electrically connected to each other and connected to artificial and natural grounding conductors.
