High voltage line clearance

WebBoth electric and magnetic fields depend on the clearance of the line. The minimum ground clearance of a 400 kV line is 7.6 m, dropping to 5.2 m for low-voltage distribution lines. See a full listing of minimum clearances for high-voltage lines under different circumstances. But in reality it is rare for lines to be this low, and the ground ... WebMay 18, 2024 · Why is the ground clearance needed ? 1) Prevent the high voltage arcing over to ground ? and/or. 2) Prevent people or objects from touching the lines, obviously touching any High voltage power line is an issue. Regarding point 1), the average field strength needed to make high voltage arc over (in dry air) is about 30kV/cm.
