Information On Lightning Conductor need and functionality. A spark of lightning occurs in a cloud when the positive and negative charges build up in such a way that a spark is produced between them. There have been numerous cases of buildings being destroyed by lightning, and humans and animals have also been killed. Taller buildings are more at risk. As a result of the lightning, the materials in the building are heated to high temperatures which start a fire. Buildings are protected from the effect of lightning by lightning conductors.
Lightning conductors are metal rods placed on top of buildings to protect them from lightning strikes. When lightning strikes this conductor, it does not hit the building directly, so there is no risk of fire or electrocution. In this way, lightning energy can pass harmlessly into the ground without damaging buildings. Earthing systems are installed from top to bottom of a building. Through a substantial metal strip, the conductor provides a poor resistance path to ground between the top of the conductor rod and the ground. As a result, currents from lightning strikes are diverted through the rod rather than flowing through the building.
Information On Lightning Conductor, they work on the principle of induction. By induction, the conductor gets charged oppositely when a fully charged cloud passes by the building, and this charge travels to the earth through the grounding system. The rod has a greater electrical length than its physical length. When there is a large electric field, air becomes a conductor, and this electric field is stronger around sharp objects than it is around flat objects.
As lightning builds up, cloud charges induce charges at the top of the pointed lightning conductor rod. As the induced charge is sufficiently large and the air around the point of the lightning conductor is sufficiently thick, the effective length of the path is extended. Information on Lightning conductors show that they are now slightly rounded because the electric field created by a charged round point is smaller than that created by a charged sharp point. In this way, the air conducting cover extends farther above the lightning conductor rod. Lightning is then allowed to strike more randomly after being ionized by air around a conductor rod.
In addition to lightning rods, lightning conductors can also be called finials, air terminals, or strike termination devices. Rods of this type may be hollow, solid, rounded, pointed, flat, or bristle brush-like. Lightning rods are characterized by their conductive conductors, which are usually copper or aluminum. Lightning protection devices are generally made of copper and its alloys. It has the advantage of making the air around it a conductor and contributing to the discharge of clouds without creating lightning and minimizing the number of chances of a lightning strike. Many devices need to be protected from external damages, such as step potentials, touch potentials, etc.
High-density ions are ionized in the outer layer of highly charged clouds, which create a negative charge around the lightning conductor and close to the cloud’s potential. As a result of this phenomenon, the lightning is attracted to accumulate opposite charges around the conductor, creating a virtual path along which the high potential electric charge can be discharged.
Lightning rods are mounted on mounting bases and connected to earth rods or ground rods using a copper cable at the upper-most corner of a building. This path allows lightning to be diverted, rather than damaging the structure, when absorbed by the lightning rod according to Information On Lightning Conductor.
Information on Lightning conductor show that they serve the sole purpose of providing a low resistance path to the lightning and allowing it to pass through the ground without damaging the structure. The thermal, mechanical, and electrical hazards of the lightning flash current must be controlled in order to safeguard people, structures, transmission lines, and electrical equipment. People and structures are both at risk, as are internal equipment and structures. It is lightning’s nature to always flow through the best conductor, whether it is a tree or a building. The electric charge will flow down the lightning conductor as soon as the fully charged cloud passes over it. In this process, no lightning will strike or thunder will sound.
