The Electric Squirrel

  1. We have a power station nearby and as you can imagine it´s the hub of numerous and thick high voltage power lines radiating into all four corners or more of the country, so it seems.
    One very high voltage line crosses or dog walk (dog amusement) path about 20 meters above and one day I accidentally lifted the flapped ears of Maxi and I noticed a strange tickling sensation, not only me but Maxi also sensed it and he looked up at me if I was loading something into his body. So there must be (there is!) a strong electrical and magnetical field in the vicinity of the power line. The experiment was repeated on several occasions, each time giving the same tickling result.

    I´ve also heard of an artist who placed fluorescent light tubes under hv power lines which made them glow.

  2. There's been a lot of talk from time to time about the electromagnetism from power lines causing health problems like cancer, but that's all hype being spread by trouble-makers for their own usually political gain.
    The important factor in all of that is the frequency of the power source and ordinary power systems are operated at too low a frequency to cause health problems from their radiation.

    I worked around power stations and their high-voltage lines all my working career, and even though I did get prostate cancer, it wasn't caused by the power lines. It happens to many of us as we get older, and the doctors say if we live long enough, we get it sooner or later. It comes with old age.
    If you would like to do some reading about those power lines and the radiation, there's a very good website run by the Health Physics Society in the USA. Just Google for www.hps.org and they have lots of information. The Society has over 6,000 members which includes engineers, scientists, power system workers, electronics experts, and nuclear experts, and they have practically written the books about radiation in all its forms.

    You and Maxi are quite safe, but there is some leakage from the high voltage systems, especially the EHV (Extra High Voltage) like 500 Kv or 750 Kv lines. At night, around the hardware fittings, you may even see what's called Corona, like tiny little lightning streaks coming off the hardware for a few inches outward.
    This is the voltage breaking down the surrounding insulating air, but the air wins about a foot away from the conductor, and it is
    quite harmless. But this kind of leakage results in transmission losses of around ten percent on the higher voltage systems. So it isn't without its problems.
    But standing under the lines will not make you glow in the dark, or make you sick. It may however make you nervous.
