Lightning is one of the natural disasters that can cause death and serious property damage. It is worth noting that not all works are protected by lightning protection systems, or that they are protected but not properly according to lightning protection system specifications. And when installing a lightning protection system, most people subjectively think that it is protected, but few people think that even a small unintentional error of the device due to long-term use will also cause great consequences if there is a lightning strike. Therefore, it is extremely important to design and periodically test a lightning protection system.<\/span><\/p>\nTable of Contents<\/p>

Maintenance and inspection of lightning protection systems should be carried out regularly, at least once a year before the thunderstorm season; it is necessary to check, repair, and replace lightning protection devices that have reduced lightning cutting capacity, measure the grounding resistance, and take remedial measures if the resistance of the grounding system is no longer satisfactory.<\/span><\/p>\n

\u2013 Determine the lightning current and the channels (locations) through which the lightning is most likely to hit the ground (avoid the vicinity of sensitive electronic equipment)<\/span>
\n\u2013 There is a harmonious coordination between the grounding system and the surge arrester.<\/span>
\n\u2013 Depending on the needs of the user, there is a choice to install direct or transmitted lightning protection devices.<\/span>
\n\u2013 Lightning rod does not rust and has high sensitivity.<\/span>
\n\u2013 Conductor is designed to transmit lightning to the ground.<\/span>
