![]() ![]() Level IV is the least restrictive, which means that, although it intercepts high current lightning, it may not capture low current lightning. The protection radius of a lightning rod for each height is calculated with the advance time of the lightning rod and the level of protection against lightning (Technical Building Code, CTE the UNE 21186 standard NF C 17-102 and NP 4426). An ESE device with a longer lead time in the formation of the upward tracer (more time in advance of the ignition), captures the downward tracer at a greater distance, protecting a larger area. Interception: DAT CONTROLER® Air terminalĮarly Streamer Emission (ESE) air terminals are characterised by continuously emitting an upward tracer to intercept the downward lightning tracer before any other element within its protection radius. External lightning protection systemĪn external lightning protection system consists of one or more lightning rod ends, two or more down conductors and an earthing system. The following is a guide to design a comprehensive lightning protection system, based on Aplicaciones Tecnológicas S.A.’s recommended products. These maximum and minimum values are used for the dimensioning of the LPS elements (thickness of the metal sheets, current capacity of the surge arresters, separation distances against dangerous sparks), for the test parameters and for the positioning of the LPS sensors. The lightning protection level of a LPS considers both the lightning current parameters and the probability of not exceeding the maximum and minimum design values in the event of a thunderstorm. The lightning protection standards define procedures for calculating the risk index of a structure to determine the required installation of a lightning protection system (LPS) and the level of protection it should provide. The purpose of a lightning protection system is to capture lightning, conduct its current safely to earth, dissipate in the ground and protect against the secondary effects of lightning. Main conductors: Generally constructed from copper or aluminum, these cables are essential in connecting air terminals to grounds.Lightning is one of nature’s most destructive events, so it is essential to protect people, the environment and infrastructures from its effects, as well as guaranteeing the continuity of services and safeguarding material and cultural assets. ![]() When lightning travels through the system, it is then buried with the rods, effectively eliminating the chance of injury or damage. Grounds: The grounds are connected to metal grounding rods that are buried approximately 10 feet in the earth. They prevent any side flashes (electricity traveling between two objects) by grounding metal objects to the main conductor cable. Bonds: Bonds are essential for the control of electric currents. They work to intercept all lightning strikes, causing them to end up harmlessly planted in the earth. Air terminals: Also known as lightning rods, these copper and metal rods are mounted vertically on the highest point of a house or commercial building. Advanced systems, such as our Transient Voltage Surge Suppression (TVSS) system, can also help protect your valuable electronics and appliances against the sudden surge in electricity caused by a lightning strike.Īt Boston Lightning Rod Co., Inc., we carefully design our lightning protection systems so that each component works together to provide you with the most advanced protection available. Instead, they work to divert the energy from a lightning strike with a combination of lightning rods, conductors, and grounds. However, it’s important to note that these systems do not attract lightning, nor are they capable of preventing lightning from striking a building. Lightning protection systems use many functions to protect your property. These protection systems are designed to provide a specific path along which a lightning bolt can travel, leading the electricity safely to grounds buried deep in the earth. We are dedicated to helping you protect your home and your family with a custom lightning rod system. ![]() In fact, the Lightning Protection Institute states that lightning strikes cause more than 400 injuries and hundreds of millions of dollars in property damage each year. Trusted Lightning Protection Systems in Dedham, MAĪ lightning strike can cause serious and costly damage to your home and your belongings. offers lightning protection systems that can help defend homes against unexpected strikes. Because lightning strikes are unpredictable, it is best to be prepared at all times. ![]()
