what's a safe distance from 230000 volt power line.?

Answer 1

Try 4' 2.4" (hint...don't use a metal ruler)

Of course, this is for trained lineworkers...

"Avoiding Flashover - The minimum air insulation distances required to avoid flashover are:

300 V and less — 0 ft., 0.03 in.
Over 300 V, not over 750 V — 0 ft., 0.07 in.
Over 750 V, not over 2 kV — 0 ft., 0.19 in.
Over 2 kV, not over 15 kV — 0 ft., 1.5 in.
Over 15 kV, not over 36 kV — 0 ft., 6.3 in.
Over 36 kV, not over 48.3 kV — 0 ft., 10.0 in.
Over 48.3 kV, not over 72.5 kV — 1 ft., 3.0 in.
Over 72.5 kV, not over 121 kV — 2 ft., 1.2 in.
Over 138 kV, not over 145 kV — 2 ft., 6.6 in.
Over 161 kV, not over 169 kV — 3 ft., 0.0 in.
Over 230 kV, not over 242 kV — 4 ft., 2.4 in."

Answer 2

Looking at the length of the insulators supporting the line will give you some idea, though personally I'd prefer to stay further than that 'cause I'm chicken, also if the lines are suspended from poles or towers, and you are of normal height, you are probably at more than a safe distance standing on the ground below the lines (whoever decided how high to hang the lines probably knows more about it than either of us).
However, "safe distance" could have various meanings, some people speculate that electromagnetic fields from power lines are hazardous, while other disagree,.But if you are, for example, building a daycare center for small children you might not want to be directly below the lines, I don't know how far away to be, but given the hypothetical scenario above, being far enough away that your clients can't see the lines would be better for business even if that is far more distance than required for safety. This would be especially true if your clients are the people who said, "the other side of the country" "six miles" etc.

EDIT: I almost forgot, if you are in (or rather hanging from) a helicopter and are wearing a "hot suit", the distance can be zero even at much higher voltage. http://www.youtube.com/watch?v=Z3q9WdjD5wc (this is SOooo cool [or hot if you prefer], especially that part at the end where he says "and I'm married too" LOL

Answer 3

In October 2000, detect magazine indexed the twenty best suited engineering errors of the previous 2 an prolonged time. EMF concerns from transmission lines made the record. Currents that don't Kill The Clinton administration estimates that American taxpayers have paid $25 billion to verify that potential lines do no longer do something greater deadly than furnish potential. In 1989, Paul Brodeur revealed a chain of articles interior the hot Yorker elevating the opportunity of a hyperlink between electromagnetic fields and maximum cancers. 8 years later, after countless great epidemiological examine in Canada, Britain, and u.s., the threat became thoroughly discounted. "All popular maximum cancers-inducing brokers act by breaking chemical bonds in DNA," says Robert Park. "the quantity of photon potential it takes is an ultraviolet wavelength. So any wavelength it rather is longer can't ruin chemical bonds. seen mild does not reason maximum cancers. Infrared mild continues to be longer, radio waves longer nevertheless. potential-line fields are preposterous. The wavelength is in miles."

Answer 4

The breakdown voltage gradient of dry air is 3 million volts/metre. In other words,if you approach a 230 000 volt line in dry air and you're earthed, then when you're 7.7 cm. away, a spark will zap you. But air always contains some moisture, so its breakdown gradient is less than this, so in practice you'd need to be much further away to be safe. I'd guess at least 5 metres.

Answer 5

Define "safe."

The typical gap used for isolation is 1mm per 1000 volts. By this standard, 230mm which is 23cm. Approximately little less than 10 inches.

But, I wouldn't get that close if I are you. In fact, I will not get any closer than 10 yards or so.

Answer 6

Maybe 5 km

Answer 7

6 miles would be safe

Answer 8

One mile would be very safe.

Answer 9

the other side of the country

Answer 10

that depends on how close it it to that puddle of water you're standing in.
