This is performed by electrical engineers using software programs that are of high accuracy and validity standards. This establishes both in which level of risk category the building or the area is included regarding the determination of the covered area and how many meters are needed for the lightning rod protection diameter. How Large Is the Area Covered by a Lightning Rod Transmitting the Lightning Safely to the Ground?Ī lightning risk assessment is carried out using specific methods for every area that needs to be protected from the lightning strike risk. Measuring terminal blocks are replaced or crimped. A continuity test is conducted on down conductors. To put it more clearly, it is the safety margin that allows for no sparking jump throughout the copper wire assembly with a down conductor until it reaches the closest grounded conductor (metal plate buried underground). The S distance, which is called the safety distance, is the protection allowance that sends the electric current to the earth in a safe and controlled way during a lightning strike. Down conductors are checked for descending by maintaining the S distance. The pole and its arrester tip are checked for any corrosion. During the lightning rod periodic inspection procedures, the system is checked for proper functioning with the help of measuring devices. It is mandatory to have the periodic maintenance, which is stipulated by legal requirements with the support of the Ministry of Labor and Social Security, carried out at least once a year. The current transferred to the ground through conducting wires is neutralized by the neutralizing property of the ground. The structure of conducting wires and the ions at the end of these wires arrest the static electric current released due to the collision of clouds. Located at the highest part of buildings or high places, lightning rods consist of a long and pointed pipe, a metal plate buried underground and copper conducting wires connecting the two assemblies. Installed at the highest point of the intended structures and also called as the external lightning protection system, lightning rods attract the lightning and deliver the current to the ground with the help of a metal rod at the tip. Lightning rods work based on the principle of arresting lightning. The methods of protection from damage caused by lightning are divided into two groups lightning preventers and lightning arresters. How Does a Lightning Rod Known for Arresting Lightning Work? A grounding system that engages before the said adverse conditions arise serves to protect both people and equipment from lightning damage against the risks of fire, loss and death. It is very likely that there will be a short circuit in various electrical appliances, electrical panels or central electric units in buildings, facilities or plants after a lightning strike. Surge arrester devices ensure that a heavy electric current referred to as a lightning strike descends to the ground safely. It is used on ships and in industrial plants and at heights that are likely to be damaged by electric currents in the air, especially high-rise buildings and skyscrapers.Ī lightning rod eliminates the potential hazards from high-current electrical energy released in the magnetic field under atmospheric conditions. It is an effective mechanism that fends off unwanted electrical charges into the ground in a controlled and safe system. On the other hand, electrical charges caused by the combination of some factors, such as temperature, wind, rain and cloud, under favorable conditions are drawn to the ground with the help of the supply earth (physical existence of the ground that makes up the earth and consists of an object or matter).Ī lightning rod is a kind of grounding system that prevents the lightning strike risk. Additionally, the magnetic air flow that is thought to be caused by different factors leads to a number of natural phenomena. The world's atmosphere accommodates electrical charges that are presumed to be caused by depending on the planetary rotation speed. What Is a Lightning Rod Classified as a Surge Arrester and What Does It Do? In the rest of our blog content, you can find all the details about a lightning rod that prevents major damages, such as loss of life and property, caused by a lightning strike. If the discharge power produced by a lightning is transmitted into the ground in a controlled way with the help of a Lightning Rod, this will prevent the damages caused by lightning currents with very high intensity. The magnetic field that perpetually exists between the sky and the earth produces lightning currents due to electrifications released under the changing atmospheric conditions. Lightning rod systems are one of the effective mechanisms that prevent potential tangible and intangible losses caused by a lightning originating from the interaction between the sky and the earth due to adverse weather conditions.
