Thesp.info Why does lightning strike tall power transmission structures?A lightning strike on tall power transmission structures is inevitable. When this surge is buried into the earth, it needs a path to dissipate. If this path is unavailable (due to high resistivity soil, for instance) the ground potential rises at the point of contact.See all results for this questionsp.info How is a bus shielded in a substation?The grounded steel structure is enough to shield the buses and apparatus below it when there are no objects to protect above the substation’s top. In small substations, masts or rods erected at the corners or columns shield the buses and apparatus falling within their protective cones (Figure 5).See all results for this question
