Device and wiring for lightning protection. The passive system of lightning protection,No one is expecting trouble from the elements. There is always hope that the disaster will bypass and will bring misfortune. As a child closes her eyes and digs under a blanket during a roll of Thunder and everyone instinctively tries to escape and hide from the raging power of nature. Science, over the past several centuries, has gone far in advance in the study of the phenomena of nature, but completely ward off trouble mankind fails. Remains only to defend themselves. One way to protect against a direct lightning serves as a passive building defeat lightning protection.
Storm activity and electrical characteristics lightning Start,The passive system of lightning protection,Passive (classical) lightning protection system is a lightning protection system, which is designed to protect the buildings from a direct lightning strike, as well as the protection of their people. While the simple construction, it has its own characteristics and must be mounted in accordance with the requirements. lightning protection system design air termination system lightning protection dissipation array system lightning protection charge transfer system lightning protection lightning protection system pdf lightning protection system ppt lightning protection systems.
Passive lightning protection system consists of lightning rods, rods, and taking United into one circuit. When you select each of these elements, the main parameter influencing the choice of a cross-section of the conductive part. The following table shows cross sections for different materials.

Each of the elements of the lightning protection have their own characteristics. At the same time with a variety of shapes and designs, there are nuances by location, connection methods, the electrical installations and lightning protection systems as a single system. Lead in lightning protection system is unique and depends on it, as will be given an electrical charge to the accordance with current best practice. This means that you need to ensure the smooth passage of his. And since the current collector is located on the outside of the building and it is subject to atmospheric influences, you should ensure maximum protection against corrosion and mechanical damage.
Grounding conductors are all electrically charged and attach it to the ground. And they must be installed in remote locations and at a safe distance from the utilities. Location and size of rods are the basic parameters, which are taken into account in the regeneration of lightning protection systems. Horizontal grounding conductors must not be laid in the ground at a depth of not less than 50 cm from the top edge of the Earth. Vertical grounding rods are installed, depending on the soil structure and calculation of earthing resistance.
Mounting of lightning rods, shunt and earthing must be tough to avoid any gap or looseness due to the electrodynamic forces or mechanical impact (vibration, falling snow formation, thermal expansion, etc.). The number of connections should be kept to a minimum. The connection must be performed in a reliable way. You can use weld or bolt fixing. Reliability of passive (classical) lightning protection depends on many parameters. Neglecting even one of them would violate the integrity of the whole system and will reduce to zero all the building lightning protection measures. Therefore, the design and installation of lightning protection should only perform a specialized organization.
