Question: Can You Touch A High Voltage Line?

Is it safe to touch a power line?

Reality: Power lines are never safe to touch.

Even a fallen power line can re-energize at any time..

How close to high voltage lines is safe?

The strongest magnetic fields are usually emitted from high voltage transmission lines — the power lines on the big, tall metal towers. To be sure that you are reducing the exposure levels to 0.5 milligauss (mG) or less, a safety distance of 700 feet may be needed. It could be much less, but sometimes more.

What happens if you touch two power lines?

When two power lines get too close together, they begin conducting each other’s electrical current and a corona discharge can be seen forming between them. This appears to us as a bluish light and is a result of the ionization of the surrounding air.

Can you touch a tree that is touching a power line?

If you climb a tree near a power line and touch the power line, electricity will go through you and you can be hurt or killed. If a tree branch falls on a power line, it can cause a power outage.

Why can birds sit on power lines and not humans?

Birds can sit on power lines and not get electric shocks because the electricity is always looking for a way to get to the ground. The birds are not touching the ground or anything in contact with the ground, so the electricity will stay in the power line.

Why are high voltage lines not insulated?

Because they carry large quantities of electricity at a very high voltage, transmission lines are not covered by an insulating sheath. The air around them provides insulation. Therefore, it’s important that nothing come close enough to the lines to cause an electric arc.
