| Abstract: | Based on the examples of certain automatic meteorological station damages caused by lightning stokes several times, the analyzed causes for damages from lightning stoke due to improper direct lightning stroke protection methods, absence of signal cable shielding measures, and non-equilibrium ground potential. This thesis also puts forward precautions including the reformation of direct lightning stroke protection, the addition of cable shielding measures and the appropriate arrangement of grounding devices. |
