The danger to you ... or to the bird, or a squirrel on the line ... has really nothing
to do with the potential on the line, or its voltage with respect to ground. Next
time there is a line crew in a bucket truck in your neighborhood, you may see a
lineman go up in the bucket, connect the bucket to the line, and then proceed to
work on the line with his hands.
The danger is the result of current through the body, and to accomplish that,
two points of the body have to be in contact with two points at different potential,
i.e. with voltage between them. That's why you don't want to touch a live circuit
and a grounded point at the same time.
If the lineman's bucket is well insulated from the boom and the rest of the truck,
then once the bucket is clamped to the line, the lineman's body is at the same
potential as the line, and he has no problem handling it. The bird is only touching
the line, nothing else, and there's no voltage difference between two parts of
the bird that can drive current through him.
The squirrel is OK if he jumps from one line to another, but he may be in trouble if he
stands on one line (neutral or primary e.g.) and reaches across to another one.
What else can I help you with?
How crow does not get electrocuted when it sit on the electric power lines?
Birds perching on power lines do not get electrocuted because they are not completing a circuit by touching another conductor. The power lines are insulated and the birds' legs are not close enough together to create a path for electricity to flow through their bodies.
Why do big birds get killed by power lines but little birds don't?
The wingspan on a big bird is large enough to touch two wires at once. Any difference in voltage between the wires will cause current to flow through the bird, perhaps killing it. Small birds can only touch one wire at a time.
Why don't birds get shocked on high voltage wires?
Birds can sit on powerlines without being shocked because, in order to be shocked, your body needs to be touching both the powerline and the ground at the same time, so that there is a path for current to flow.If birds sit on a powerline, they aren't touching the ground. This means that they will not be shocked.Another explanationTo be electrocuted you not only need a point at which the electricity enters your body but also a point at which the electricity exits your body. Because the birds are only touching one wire there is no place for the electricity to exit, and this prevents them from getting electrocuted.
What happens if someone touches a high voltage wire?
If they are grounded they get an electric shock or electrocuted. If they are not grounded or in simultaneous contact with the neutral wire, nothing. That's why birds can sit on a high voltage wire and survive; they are not grounded.
Why do birds sit together on telephone lines?
For a start, most telephone wires are insulated and carry little or no electricity so, apart from falling off and hurting themselves, they won't get hurt on telephone wires. Really, you should have asked about why birds don't get hurt on overhead electrical wires. The answer is fairly simple really - to get electrocuted from those wires you need to complete the circuit, in this case touch the ground, for the electricity to surge through the body. Birds only sit on the wire and do not touch the ground, so they can't be electrocuted.
Why don't birds get electrocuted sitting on a wire?
Very interesting...A current will flow (or somebody will get electrocuted!) if there is a sufficiently high potential difference across him.When birds sit on a wire (of high potential), the whole body becomes at a high potential, and there is no potential difference across it. Hence, no current passes through it and the bird is not electrocuted.However, if a person, while standing on the ground, touches the same wire, he will be electrocuted.add You've discovered one of the reasons why overhead electric wires are separated from each other. We do have blackouts caused by a bird or an opossum (Aus) bridging between the wires. In NZ in suburbia, almost all power poles have a wide metal band on them to stop the possums from climbing them.
Why don't birds get electrocuted when they sit on telephone wires?
Birds fall from the window ledge above mine, flapping their wings at the last second towards a horizontal flight. Due to a construct in my mind it makes their falling and their flight symbolic of my entire existence. If you want to electrocute birds, all you need is a bug zapper, hence the name.
Where can you find a bird?
Well, birds are ususally mostly everywhere. You can find them flying in the sky or nesting their home in trees. Some birds even sit on top of telephone poles. So you can find them anywhere. you can also find them on ground, in the woods and at ur house
