| Popis: | Lightning protection is required to ensure safe and stable electric railway transportation. In this thesis, the lightning surge characteristics of the facilities in electric railway systems were measured. The characteristic of earthing impedance was also investigated from the viewpoint of lightning surge. In addition, some numerical models of railway specific apparatuses for circuit analysis method were developed by applying simulation technology for power system and confirmed their accuracies by actual measurements. The responses to lightning currents invaded into the facilities were clarified by the measured and calculated results. These results can be fully utilized in the design, maintenance and analysis of electric railway systems. Doctor of Philosophy in Engineering Doshisha University |
