What is a lightning rod? What are the Types and Principle of Operation
<p>A lightning rod is a device designed to protect a structure from lightning. It is used to prevent damage caused by lightning. Lightning rods are installed on the roofs of structures located in a high position or at other high points. These devices prevent lightning strikes and reduce the damage that may occur to the structure.</p> <p>The principle of operation of lightning rods is based on preventing lightning from striking and damaging the building. There are two basic types of lightning rods:</p> <p>1-Air Lightning Arrester (Overhead Lightning Arrester): It is the most commonly used type of lightning arrester. This type of lightning rods, due to their high resistance, form the core of lightning, forming a conductive path with air. This way allows the lightning to reach the ground safely. Air lightning arresters usually consist of a metal rod mounted on the roof or structure.</p> <p>2-Earth Lightning Arrester (Grounded Lightning Arrester): Earth lightning arresters are used to prevent lightning from striking and to ground energy. There is a conductive tip placed at the top of the structure, and this tip prevents damage by transmitting energy to the soil layer when lightning strikes.</p> <p>Lightning rods usually consist of several basic elements:</p> <p>Conductive Tip: Mounted at the highest point of the structure, this tip forms the core of the lightning.</p> <p>Leading Wire: This wire, which extends from the conducting end to the ground level, is used to transmit the energy of lightning to the soil layer.</p> <p>Grounding System: A metal rod or network located at ground level safely transmits lightning energy to the ground.</p> <p>Lightning rods are used to prevent fires, structural damages and other damages that may occur as a result of a lightning strike. Regular maintenance and tests should be carried out to increase the safety of structures and minimize environmental hazards.</p>
