Why don't birds get electrocuted on power lines?

This video explains the basic reason and science behind "Why don't birds get electrocuted on power lines?" while humans can't touch energized lines without getting shock. In the coming videos, it will be explained how humans can carry maintenance of energized power lines (Extra high voltages) safely.

Sir i have a doubt, we all know there will be magnetic field around a current carrying conductor.so for high voltage lines like 110kV 400kV 33kV have larger magnetic fireld...So. If a bird stands in a pole and tge HV conductor is very near and the bird is under the magnetic field, will the bird get electrocuted...Ir there is a chance for flash over... please explain❤

The current always follow the path with least resistance. So it will flow through the conductor, rather through the bird's body. Even if the bird comes in electromagnetic zone on HV lines, it may feel a lil shock but due to absence of return path, current will not flow and there will not be any harm caused. Even linemen can work on energized circuits with special conductive uniform. i will make a video on that sometime that how maintenance work is executed on energized high voltage circuits.

Is there any hazard risk of getting electric shocks if the internet fiber cable is touching a naked electricity wire running between two poles? Fiber cable doesn't conduct but will there be any risk when it is going to be wet in rain?

[@theengineeringpower4213]

As fiber cables are designed to transmit light rather than electricity, so you won't get any shock. However if the fiber optic cable is enclosed by a metallic body for protection, it will conduct electricity resulting in shock. e.g. in case of high voltage transmission lines, fiber cables are passed on the same towers above the conductor (used for transmission of data between grid stations and also functioning as earth wire for protection against lightening strikes)and those fiber cables are enclosed by layers of aluminium strands which can pass electricity when come in contact with live wires.

@@theengineeringpower4213 my internet fiber cable from my house is touching electricity lines running between the electricity poles in front of my house. Fiber cables are pvc-insulated but I'm worried if they can be risky after getting wet in heavy rain. Should I worry?

[@theengineeringpower4213]

No you don't need to worry as for conduction of electric current, the whole path of fiber cable must be conductive whereas during rain, there is no chance for that. There is chance of conduction during rain only if the path is a small vertical one as it's easy for rain water to form a conductive path on a small vertical portion but not on that long horizontal wire.

​@@theengineeringpower4213 It's approx 5-6 meters, not exactly horizontal but at an angle. It's a new connection and this is its first rainy season. I can't stop overthinking about theoretical possibilities of risk.

[@theengineeringpower4213]

@@croncog No need to worry. There is nothing dangerous in your case.

There is a electric potential difference between bird and the wire so why don't the current just enter in the bird ?

[@theengineeringpower4213]

Current always follow the path with minimum resistance. The Wire resistance is much lesser as compared to the bird's body when on same phase. The potential difference between the two feet of the bird is negligible due to same phase. The same principle is used by Live Live workers performing maintenance of high voltage transmission lines while electricity is flowing through the conductor. The Live man, technically termed as "hot man" sits on live energized conductor while performing necessary maintenance work. special conductive uniform is used for that purpose. I will shortly make a video on that.

A load of bollocks really, there is a high potential difference but it doesn't exceed the breakdown voltage of the air.

[@theengineeringpower4213]

There is negligible potential difference on two close points of conductor of the same phase. That's the main reason behind the non-electrocution of the bird.
