Cooperation between French energy company EDF and the League for the Protection of Birds (LPO), a French environmental association, has helped protect birds from electrocution, TF1 Info reported on May 10.
French conservationists are concerned about protecting birds from the effects of electrical current. Many people have often seen flocks of birds resting peacefully on electrical wires, unharmed by exposure to electrical current. If a person did this, he would receive a fatal electric shock.
A study on the reasons why birds stay safely on the cables showed that they are protected thanks to various physical laws. It is true that the size of the birds played an important role here. According to the physical laws associated with the conduction of electricity, due to their small size, the birds had a low electrical potential, which prevented the passage of current through them along the wires on which they sat. .
Furthermore, their feathers served as insulation and the air around them was not a conductor of current, unlike metal or water. In addition, the poles with wires were located high above the ground, which prevented contact with it as with another conductor. The birds themselves touched only one electrical wire.
Additionally, the small size did not allow the birds to short-circuit adjacent wires or arc between them, which could lead to the death of the bird. Therefore, a large bird with a large wingspan, such as an eagle, a condor or a vulture, could die when landing on an electrical cable.
Knowledge of these dangers to birds has helped environmentalists, along with energy workers, develop a series of measures to protect them. In particular, covering the cable with a plastic insulating sheath, using ceramic insulators in high-voltage power lines. In several places it has been proposed to install devices that prevent birds from landing on cables or bird-repelling systems.
