11000kV Wires vs 11000kV to 220V Transformer

https://www.gov.uk/government/collections/electromagnetic-fields

The transformer looks dangerous, the wires probably don,t. Therefore, i would say you are safer now.

I am talking about emf from wire and transformer

As you have demonstrated, one danger is developing a case of electrophobia. A more real danger would be if you actually contact the wires or terminals of any high voltage electrical device.

I hope that you have all of your affairs in order.

EMF exposure has been found to contribute to the following:

Disruption in cell protein production

Genetic damage and mutation

Creation of stress proteins

Immunity impairment

Cancers (multiple types)

Reduced melatonin

Changes in electrical activity in the brain

Cardiovascular stress

Cytogenetic changes in brain cells

Electrophysiological disruption of the nervous system

Changes in various neurotransmitters

Metabolic changes in brain tissues

C'mon, consider the source before you post such a pile of unverified drivel, rumors, and innuendos! That newsletter is a front for a MultiLevel Marketing scheme that appeals to the electrophobics out there. At least provide some data from peer reviewed, refereed, scientific journals, not pay to publish pruedoscience.

Sometimes, I just can't resist the impulse to poke the hornets nest.

11,000 kV = 11,000,000 (eleven million) volts. You did not live 2 meters from 11 million volt power lines, you would have died. The dielectric strength of air is about 3,000,000 V/m, so 2m of air space was close enough that it would have flashed over to you like a bug on a zapper.

Now, if you meant 11kV (eleven thousand volts), then 2m would not allow flashover, but would not be considered safe in most civilized countries.

Mid your concern is for the hysteria going around on living near power lines, you likely will not find a lot of sympathy here. Many (if not most) of us have been working around electomagnetic fields for the majority of our lives and we are just fineghuchyyfcjuhvyvjuybseln.

Yes yes i was talking about 11kv wire. I Apologies for my mistake. But other question was that which emits more emf 11kv to 220v pole mounted distribution transformer or 11kv wire carring current

Again, you are wasting your time and psychic energy on a non-problem. If it were a problem you would expect to see the results exhibited in a significant portion of the population of the civilized world that has access to electricity. The problem(?) has been studied, experiments performed, research papers published, and few have shown any credible repeatable evidence of any biological effects.

As far as the transformer versus powerline question; the internals of most distribution transformers are surrounded by a tank which acts as a sheild and can be considered as a point source of radiation so any field falls off as the 4th power of the distance from it. A three phase distribution line arranged in a triangular configuration is nearly fully balanced so the field is close to nil, and any field due to imbalance would fall off as the square of the distance from it.

But to be safe, don't wrap yourself in an electric blanket...and please don't use your microwave oven or stand near a cellphone or tower. They all emit miniscule, yet measurable, amounts of ionizing radiation at levels much higher than the nonionizing radiation available from the power lines that feed them.

Is microwave oven radiation, wavelength 20 - 30mm ionising radiation? I thought ionising radiation was X-rays, γ-rays and from radioactive material, but I stand to be corrected.

You are correct, microwave energy, despite having a heating effect, is non-ionizing.

Thanks, thought so. Microwaves are still dangerous because they cook you, starting with the eyes I believe, but not because they're ionising.

"surrounded by a tank which acts as a sheild and can be considered as a point source of radiation so any field falls off as the 4th power of the distance from it. "

Please can you explain this in simple english

I'd venture to guess that he was assuming it would be an oil filled utility distribution transformer.

So there would be a large steel tank filled with silicon oil used to keep the transformer cool and insulated, and that steel tank is essentially also going to act as an electromagnetic shield. So any EM radiation that gets past it is going to be extremely low.

Thanks, but that picture is more illustrative of a bulk power transmission transformer, but the concept is the same. I did make an error though, the power from a single point follows the inverse square law, radiated power decreases as the square of the distance from the source.

In layman's terms, if the radiated power measured one distance unit from the source is 1 power unit, then when you move 2 distance units away the source the measurement is only 1/x² or 1/2² = 1/4 as strong. Move 10 units away and the power is only 100^th as strong.

From Wikipedia

The answer is, neither is anywhere near what you were exposed to in posting your question on a mobile device or a PC with a wireless modem. If you are really concerned, wrap yourself in aluminum foil and go live in a desert as far away from any kind of technology.

Neither is especially good for either tightrope walking or falling off from height. Therefore it is difficult to suggest which is more dangerous.

However, <...11000kv...> is about 1000 times as dangerous than 11kV, though...

The old smoke detectors were ionizing though. I don't know if they still are, I haven't cracked one open in years now (other than to change batteries). But it used to be that they had that ionizing radiation hazard symbol on them if you looked under the cover. Americium I believe.

Now that I have stopped laughing about the figures quoted I wonder why you are still alive and the structures you lived in then and now are still upright.

11,000KV is 11,000,000 volts. In the US at least, the highest normally built high tension system is 250KV. Occasionally 500KV is permitted. The closest to me makes a mild crackling/humming noise during snow storms. No ghosts, hermits, giant frogs or gorillas.

The distance for arcing between 2 spherical shaped electrodes in dry air is about 75kv./in (similar to pictures from Telsa's lab). At 11,000kv anything such as open wires would normally not begin to arc between them until they were closer than 146.67in, (3.73m). You could possibly survive the close proximity to the 4 meter line distance but you wouldn't have to worry about the 2 meter situation. You will be dead from electrocution when you get at the 3.73 meter range. That is not necessary true if you are ungrounded, an experienced high voltage lineman/woman or as they use around here the lineman who works from a helicopter.

Also, don't measure distances between you and the wires with a metal tape measure.

Good Luck, Old Salt

<...could hold those wires from rooms balcony...>

That sounds a bit <...dangerous...>. That would only happen for a split second before the person doing it had a personal lights-out moment.

What idiot signed off that installation as "safe"?
