Soil resistivity plays a central point in the vulnerability of a sub administration pipeline resource being struck by lightning. The target of this report is to build up rules for the establishment of single earthing indicates in nearness high weight gas pipelines. Soil resistivity is the most powerful factor on the impacts of a lightning strike on sub surface resources. Limited soils can possibly differ enormously; the models communicated in this archive might be as exact as the estimation taken. A lightning channel strike circuit by means of a sub-surface conductor comprises initially of the striking of an over the ground defensive gadget. From that point, the current is occupied to the earth stake or sub-surface conductor. The present at that point streams from the conductor through ground zone 1. This zone comprises of the spiral soil obstruction between the closest point to the pipe and the earth stake. The obstruction of this zone is called R(to_pipe). The hypothesis accept we have spiral current stream. Since ground obstruction is frequently not uniform this presumption may display some impediment in states of high soil opposition change.
