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.<\/strong><\/p>\n<p>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.<\/p>\n<p>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. 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.<\/p>\n<p>The following is a guide to design a comprehensive lightning protection system, based on Aplicaciones Tecnol\u00f3gicas S.A.&#8217;s recommended products.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"External_lightning_protection_system\"><\/span><strong>External lightning protection system<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>An external lightning protection system consists of one or more lightning rod ends, two or more down conductors and an earthing system.<\/p>\n<h3><strong>Interception: DAT CONTROLER\u00ae Air terminal<\/strong><\/h3>\n<p>Early 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.

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 <a href=\"https:\/\/tienda.aenor.com\/norma-une-21186-2011-n0048559\" target=\"_blank\" rel=\"noopener\">UNE 21186 standard<\/a>; NF C 17-102 and NP 4426).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"img-responsive img-fluid aligncenter wp-image-26913 size-full\" src=\"https:\/\/at3w.com\/wp-content\/uploads\/2021\/07\/tb-1-en.jpg\" alt=\"\" width=\"1034\" height=\"277\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"img-responsive img-fluid aligncenter wp-image-26918 size-full\" src=\"https:\/\/at3w.com\/wp-content\/uploads\/2021\/07\/tb-2-en.jpg\" alt=\"\" width=\"1034\" height=\"301\" \/><\/p>\n<p>Level IV is the least restrictive, which means that, although it intercepts high current lightning, it may not capture low current lightning.

These very short-lived voltage surges are introduced into equipment via power, telephone, television or data supply lines. Overvoltage protection maintains continuity of service by reducing the likelihood of safety incidents to an acceptable level for people and property. Surge protection devices are characterised by being inactive when the electrical signal is normal, but respond instantaneously to transient surge peaks, conducting the lightning current to earth and protecting equipment. Once the surge is absorbed, the DPS returns to its idle state. The types of overvoltage are as follows:<\/p>\n<ul>\n<li>Type 1: protect against the effects of direct lightning strike and are therefore installed in places where lightning currents and electromagnetic effects of lightning are not attenuated (main switchboards).<\/li>\n<li>Type 2: protect against the secondary effects of lightning, in places where lightning currents and electromagnetic effects are already attenuated (secondary frames).<\/li>\n<li>Type 3: protect against overvoltages that are already very damped, leaving very low residual voltages.
