Abstract: Lightning protection for buried gas-pipelines has not yet being studid. Gas-pipes made of steel are covered with polyethylene sheath. When there is a high structure nearby the gas pipelines, the polyethylenefs insulation may be destroyed by lightning surge. In this study, we have evaluated the possibilities of insulatin breakdown of polyethlene sheath using a finite element method. As there is no rule on countermeasures in the world, we have to investigate the phenomenon when a lightning strikes the pipelines. Even the gas company normally use aditional sheath pipe or griddles to protect the gas pipelines from lightning surge , the effectiveness of these counter measure methods have not yet been evaluated. In addition to these methods, we have also investigated on the effectiveness of buried shielding wire normaly used for burial telecommunications lines. In this study, we have simulated various lightning protection measures such as a sheath pipe, griddles and !
buried shielding wire by using finite element method so that called JMAG.
