how to calculate lightning protection level

PDF REPORT

When analyzing the project, you will obtain a complete and personalized technical report with the characteristics of the lightning protection system that your structure needs to protect.

Calculation of the level of protection according to the regulations IEC 62.305-2, UNE 26.186: 2011, NFC 17.102: 2011.

You can carry out all the projects you need.
