The main switchboards in facilities should be protected by B+C class surge protective devices that provide protection against both lightning and grid surges. Likewise, secondary panels in facilities should be protected with <strong>C class surge protective devices<\/strong>.<\/p>\n<h2><span style=\"color: #ff6600;\">Protection of Sensitive Systems and the Up Concept<\/span><\/h2>\n<p>Natural gas facilities contain many sensitive devices. The most common problem is damage to these sensitive devices due to insufficient protection. The Up protection level is critical at this point. With surge protective devices used in main and secondary panels, the Up level of incoming surges can be reduced to a certain extent. However, the Up tolerance of sensitive systems is much lower. Therefore, D class sensitive surge protective devices should be installed in front of these devices. These sensitive devices in natural gas facilities can be listed as follows.<a title=\"Free Technical Survey Application\" href=\"https:\/\/yilkomer.com\/en\/free-technical-site-survey-application\/\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"wp-image-3818 aligncenter\" src=\"https:\/\/yilkomer.com\/wp-content\/uploads\/2015\/03\/teknik-ke%C5%9Fif.png\" alt=\"technical-survey\" width=\"748\" height=\"126\" \/><\/a>Pressure measuring devices<\/p>\n<ul>\n<li>Flow measuring devices<\/li>\n<li>Level measuring devices<\/li>\n<li>Compressors<\/li>\n<li>Communication lines (ethernet, RS)<\/li>\n<li>PLC and RTU systems<\/li>\n<li>Signal converters<\/li>\n<\/ul>\n<figure id=\"attachment_5191\" aria-describedby=\"caption-attachment-5191\" style=\"width: 496px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/yilkomer.com\/wp-content\/uploads\/2016\/03\/boru-hatt%C4%B1.jpg\" rel=\"attachment wp-att-5191\"><img decoding=\"async\" class=\"size-full wp-image-5191\" src=\"https:\/\/yilkomer.com\/wp-content\/uploads\/2016\/03\/boru-hatt%C4%B1.jpg\" alt=\"Pipelines must be protected against surge impulses with surge protective devices.\" width=\"496\" height=\"358\" \/><\/a><figcaption id=\"caption-attachment-5191\" class=\"wp-caption-text\">Pipelines must be protected against surge impulses with surge protective devices.<\/figcaption><\/figure>\n<h3><span style=\"color: #ff6600;\">Use of Spark Gap Surge Protectors<\/span><\/h3>\n<p>Due to resistance differences between natural gas pipeline systems, possible leakages can create sudden spark impulses.
