Abstract Research purposes : The study is done on the actual application of grounding for lightening protection for metro station for the purpose of providing safe and comfortable environment for passenger&staffs.
Research results:The steel bar couple with manual grounding network in overhead waiting hall and application of SPD for power supply device provide good ways for over-voltage protection and current-release. The integration of equipotential coupling, natural grounding body, manual grounding network and surge protection device(SPD ) can be used for grounding for lightening protection far metro station.
