safe distance from power line?

Question

What is the safe distance for living near overhead high voltage electricity power lines? I want to purchase a piece of land (to build a house) and noticed an overhead high voltage electricity line (110 kv) about 80-100 meters away. Is this distance safe for living near that line?

Answer 1

Nobody really knows. This is a controversial topic. Some studies show biological effects on cells, while others studies show no measurable effects. However, some researchers believe there is a link between the proximity of power lines to schools, and the leukemia rate of the children that get exposed to the 60Hz magnetic field while at school. I remember one researcher found that a 60Hz magnetic field strength of 2mG produced measurable changes in the activity of cells in the lab.

You might want to consider buying the device called "Cell Sensor" given in the 1st link below. It measures the 60Hz magnetic field. Also, realize that the strength of the field will vary over the course of the day. On a hot summer day, when all the air-conditioners are running, that should be the worst case.

Also know that there is no practical way to shield against 60Hz magnetic fields.

You should find the two links below useful. Good luck.

In October 2000, Discover magazine listed the twenty greatest engineering blunders of the past 20 years. EMF concerns from transmission lines made the list.

Currents That Don't Kill
The Clinton administration estimates that American taxpayers have paid $25 billion to determine that power lines don't do anything more deadly than deliver power. In 1989, Paul Brodeur published a series of articles in The New Yorker raising the possibility of a link between electromagnetic fields and cancer. Eight years later, after several enormous epidemiological studies in Canada, Britain, and the United States, the danger was completely discounted. "All known cancer-inducing agents act by breaking chemical bonds in DNA," says Robert Park. "The amount of photon energy it takes is an ultraviolet wavelength. So any wavelength that is longer cannot break chemical bonds. Visible light does not cause cancer. Infrared light is still longer, radio waves longer still. Power-line fields are preposterous. The wavelength is in miles."

Answer 3

There is a lot of controversy about the effects of electromagnetic radiation on the 50/60hz band. Personally, I would steer clear, but if you want to live there after doing the research, see if you can get a lower price by mentioning possible health risks.

Answer 4

I was 100 feet from a power transmission line. I was fishing in a stream using a 15 foot graphite rod. As I cast the graphite rod, the movement of the graphite rod through the magnetic lines of flux created such a strong current that it knock me on my tail... I got zapped because I had inadvertently created a generator out of the graphite fishing rod cutting through the high intensity magnetic lines of flux. Cows are known to deliver pre term calves when they are grazed under or near the power transmission towers.

Answer 5

The breakdown voltage gradient of dry air is 3 million volts/metre. In different words,in case you physique of recommendations a 230 000 volt line in dry air and you're earthed, then once you're 7.7 cm. away, a spark will zap you. yet air consistently incorporates some moisture, so its breakdown gradient is decrease than this, so in prepare you may must be plenty extra away to be risk-free. i might wager a minimum of 5 metres.
