One of the popular types of lightning rod is a vertical mast, which is a steel pipe of various lengths and cross-sections that effect the protection radius and lightning resistance. The cross-section of a lightning rod is chosen to avoid melting when lightning current acts on it with specific energy of 10 MJ/Ohm. This energy level corresponds to calculated data on the first current impulse of lightning for the first level of protection in accordance with SO 153-34.21.122-2003, which is higher than other levels of protection. In this way, the cross-sections are designed to receive the maximum possible lightning current. If the thermal and mechanical aspects are of significant importance, the cross-sectional area may be increased from 50 sq mm to 60 sq mm. This is relevant for particularly important facilities, where a lightning rod is to be working at all times, as well as for areas with a high thunderstorm rate.
The ZANDZ.ru project took part in the large-scale international industrial forum Business and IT. Around Data Center. Around Data. Around IP, that took place on November 12 in Sochi . It is not the firstevent arranged by the Information and Marketing Agency CIS Events Group intended to discus current issues in operating data processing centers and servers. Each forum brings together top experts from the industry: designers, engineers, and top and mid-level managers. The ZANDZ.ru project shared a report with its participants on the topic of providing grounding and lightning protection for data processing centers. The speaker was Igor Panov - an expert in the field of telecommunications and information technology.
According to the paragraph 3.2.3.1. in the Manual SB 153-34.21.122-2003, the ground electrode should be buried to a depth of at least half a meter from the ground surface. Normally, the following question arises after installing the system: should the place of installation be left open or can it be covered with asphalt?
