The introductory chapter discusses the current IEC/EN 62305 standards. These are standards in the field of lightning protection. The third chapter discusses sources of damage with respect to the location of the lightning strike, types of damage and losses. Furthermore, the fourth chapter describes risk, types of risk and risk management based on its components. The decision on the need for protection is made based on existing standards. Optimal protective measures are selected with respect to technical and economic aspects. The fifth chapter deals with the design of lightning protection systems, where methods for designing the arrester, down conductor and grounding systems are listed. Three methods of the arrester system are listed: the rolling ball method, the protective angle method, the conductor network method. The conductor network method is used in the demonstration example. When designing the down conductor system, natural down conductors and the measuring connection are mentioned. In designing the grounding system, there is a type A system and a type B system. An example of a building with lightning protection is in the sixth chapter. All data that serves as criteria for selecting the type of protection is listed. A lightning protection calculation has been performed for a car mechanic workshop.
