Research on the Characteristic for the Dielectric of Building and the Material of Grounding by Lightning Stroke
How to effectively prevent the electronic equipments and information systems in building from lightning hazard is a key problem to lightning-protection. Here is a simulation model established for analyzing the electromagnetic field distribution of building, which is hit by lightning strike. The electric field intensity and voltage distribution of cement wall and soil medium are calculated by ANSYS software. The simulation results show that there are many kinds of lightning in nature. Therefore, lightning-protection measures should be based on specific structure features and characteristics of buildings internal device. The damage of lightning presents new characters and the damage degree of lightning induction is deeper than direct lightning strike. And the simulation results can also be a reference in the design of building lightning-protection.
