Lightning damage is one of the important factors that affect the stable operation of seismic stations; thus, it is of significance to protect the stations from lightning. This study introduced the design of a lightning protection system for the geoelectrical resistivity monitoring stations in the Winter Olympic Games security project. Through the analysis of problems in the key design techniques of the lightning protection system, the overall design of a comprehensive lightning protection system in terms of the aspects of grounding grid, power supply, and comprehensive wiring was discussed, and the lightning protection system at Baochang Station was designed. On this basis, the design of the lightning protection system of all eight stations in the project was completed, and the effectiveness of the lightning protection system of the stations was improved. In this study, some new technical achievements were attained, i.e., (1) the power supply and measuring lines were buried; (2) the buried power supply and measuring lines were more than 10 m from the grounding body; and (3) the network signal lightning arrester with corresponding current values was installed in the stations that still used overhead lines. These research results can be used as a reference for the construction of the lightning protection system for national stations in the future.
