The main task of a lightning protection system is to capture the lightnings, which strike the building. It is important to avoid thermal mechanical or electrical side effects, since it can cause damage of securable object structure and appearance of, dangerous for human, contact or pace voltage inside the building. The main task of the lightning protection is to prevent the danger of spark formation inside the protective building structure.
Sparking occurs in such cases, when during the passage of lightning current through a conductor (lead wire), a high potential difference arises between metal or electrical conductive parts of the unit. Power supply equipment, wired and wireless communication equipment require the special protection, since, a direct connection between the outer lightning rod and the electrical wiring in the house is supported through the grounding and potential equalization system.
