Lightning rod systems commonly encountered in our country are designed based on the NFC 17102 standard. In this article, we would like to bring up a very important topic that is included in the standards and must be emphasized while directing lightning discharge with external lightning protection systems: <strong>\u201cInsulation\u201d<\/strong>.<\/p>\n<p>While the lightning discharge captured by <a title=\"External Lightning Protection\" href=\"https:\/\/yilkomer.com\/en\/external-lightning-protection-systems\/\" target=\"_blank\" rel=\"noopener\"><strong>external lightning protection systems<\/strong><\/a> is conducted down to the grounding area, it may jump to <strong>power<\/strong> and <strong>data<\/strong> lines and often cause serious damage due to coupling effects. In addition, bare conductors installed directly against the building can lead to dangerous outcomes such as fires and risks to human life. Therefore, lightning discharge must be conducted to the ground in an insulated manner, away from the structure. To achieve this, standards provide us with two alternatives.<\/p>\n<ul>\n<li>Using insulated conductors tested at lightning discharge levels ()<\/li>\n<li>Maintaining the \u2018S\u2019 separation distance calculated by considering the physical characteristics of the building using relevant formulas.<\/li>\n<\/ul>\n<h2><strong><span style=\"color: #ff6600;\">Calculation of the S Distance<\/span><\/strong><\/h2>\n<p>Generally, maintaining the \u2018S\u2019 separation distance should be ensured with special insulated products.

Regardless of the external lightning design\u2014whether cage method or Faraday method\u2014ensuring down conductor insulation and providing symmetrical down conductors from two points are extremely important. Insulated conductors provide insulation for impulses up to 200 kA. Considering that the average impulse in our country is 50 kA and can reach up to 100 kA in southern regions, these systems stand out as a significant method for establishing safe lightning protection systems. However, as we always emphasize, we cannot protect our facilities with external lightning protection systems alone. Lightning protection systems are like a table standing on four legs. To maximize facility safety, internal lightning protection systems, equipotential bonding, and a proper grounding system must also be implemented.<\/p>\n<p>In the table below, you can see the difference between systems with and without S separation distance and systems using <b>insulated conductors<\/b> .<\/p>\n<figure id=\"attachment_3298\" aria-describedby=\"caption-attachment-3298\" style=\"width: 560px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/yilkomer.com\/wp-content\/uploads\/2014\/02\/Y%C4%B1ld%C4%B1r%C4%B1m4.jpg\"><img decoding=\"async\" class=\"wp-image-3298\" src=\"https:\/\/yilkomer.com\/wp-content\/uploads\/2014\/02\/Y%C4%B1ld%C4%B1r%C4%B1m4.jpg\" alt=\"OBO iscon\" width=\"560\" height=\"384\" \/><\/a><figcaption id=\"caption-attachment-3298\" class=\"wp-caption-text\">Due to fire hazard risks in areas such as fuel stations and filling facilities, the use of insulated lightning discharge conductors is a more common solution.<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>An <strong><a title=\"Protect Your Devices from Overvoltage\" href=\"https:\/\/yilkomer.com\/en\/protect-your-devices-from-overvoltage\/\" target=\"_blank\" rel=\"noopener\">insulated lightning protection system<\/a><\/strong> must be implemented as a whole with all its components.
