How far can power jump from power lines?
|Voltage (kV)||Minimum clearance distance (feet)|
|Up to 50 kV||10 ft|
|>50 to 200 kV||15 ft|
|>200 to 350 kV||20 ft|
|>350 to 500 kV||25 ft*|
What causes a power line to jump? If ice loading is suspected, it may be possible to increase power transfer on the line, and so raise its temperature by Joule heating, melting the ice. The sudden loss of ice from a line can result in a phenomenon called “jump”, in which the catenary dramatically rebounds upwards in response to the change in weight.
Can you get shocked by a power line? This is a common misconception that many people have about power lines. Power lines are not insulated and you should always avoid contact with them. It is quite possible for people to get electrocuted if you touch power lines.
How do lineman not get electrocuted? A live line worker is electrically protected by insulating gloves and other insulating equipment, and carries out the work in direct mechanical contact with live parts. The barehanded approach has a live line worker performing the work in direct electric contact with live parts.
