Analysis of the Use of Active and Passive Lightning Conductors

The article deals with the issue of external lightning protection, comparing two systems of this protection. These are the external ESE lightning protection system and the external LPS lightning protection system. In the first part of the article, the legislation on lightning protection is presented, and indoor lightning protection is also discussed. Subsequently, the article contains a theoretical comparison of the risk analysis according to STN EN 62305–2 and NF C 17–102. The aim is to highlight the differences in the relationships, probability, and loss determination used to calculate the risks in both standards. The paper analyses the design of external lightning protection according to both standards for a selected building structure. The article concludes with recommendations on external lightning protection.
