Numerical Analysis of Lightning Electromagnetic Environment inside a Typical Telecommunication Building

Abstract

This paper presented a numerical evaluation of the lightning electromagnetic environment inside a typical telecommunication building when a lightning strikes at its lightning protection system (LPS). A model based on ‘circuit approach’ was constructed to simulate the building reinforced steel structure. Through numerical simulation, the magnetic field inside the building for two different types of LPS and for two typical lightning stroke positions was evaluated and compared. From the analysis result, some advices were proposed to protect electronic equipment against the impact of the magnetic field.
