After external grounding, it is technically important to connect it to the building grounding or the main grounding of solar power plants. Misconceptions about this are unfounded; even if there is a resistance difference, a lightning strike affecting an area of 2 km will flow into the systems within nanoseconds. However, when equipotential bonding is provided, the strike will split at the point of impact and flow towards the area with lower resistance, preventing damage.<\/p>\n<blockquote>\n<p style=\"text-align: center;\">You may be interested in: <strong><a href=\"https:\/\/yilkomer.com\/en\/lightning-air-terminal-franklin-rod\/\" target=\"_blank\" rel=\"noopener\">Lightning Rod (Franklin Rod)<\/a><\/strong><\/p>\n<\/blockquote>\n<p><a href=\"https:\/\/yilkomer.com\/wp-content\/uploads\/2015\/12\/dis-yildirimlik.jpg\" rel=\"attachment wp-att-4777\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-4777 aligncenter\" src=\"https:\/\/yilkomer.com\/wp-content\/uploads\/2015\/12\/dis-yildirimlik.jpg\" alt=\"external-lightning-protection\" width=\"664\" height=\"376\" srcset=\"https:\/\/yilkomer.com\/wp-content\/uploads\/2015\/12\/dis-yildirimlik.jpg 664w, https:\/\/yilkomer.com\/wp-content\/uploads\/2015\/12\/dis-yildirimlik-300x170.jpg 300w\" sizes=\"(max-width: 664px) 100vw, 664px\" \/><\/a><\/p>\n<p>Performing lightning protection grounding at 50 meters, 100 meters, or 200 meters away has no technical significance. Standards and technical experience confirm this. External lightning protection grounding can be connected to an equipotential bus using spark gap surge protectors. This will prevent electrical systems from being exposed to a direct strike. However, due to the four-layer protection principle we always emphasize, <strong>LV <span style=\"text-decoration: underline;\"><span style=\"color: #ff6600; text-decoration: underline;\"><a style=\"color: #ff6600; text-decoration: underline;\" href=\"https:\/\/yilkomer.com\/en\/lv-surge-arrester\/\" target=\"_blank\" rel=\"noopener\">SURGE PROTECTORS<\/a><\/span><\/span><\/strong> must always be used on both AC and DC lines. This way, by installing an external lightning protection system, we protect our facility from direct lightning strikes and also provide electrical protection via LV surge protectors.
