What is a lightning ground system?
A lightning ground system should be capable of dispersing large amounts of electrons from a strike over a wide area with minimum ground potential rise. It should be capable of doing this very quickly (fast transient response).
How do you protect a power station from lightning?
In most cases the best approach is to drive one or more ground rods into the earth near a window or access point to the station. Bonding to this ground rod will provide needed protection against electrical hazards and provide some lightning protection.
What is an effective station electrical ground?
An effective station electrical ground bonds the chassis of all station equipment together with low-impedance conductors and ties into a good earth ground as near as possible, or where the electric service panel has its origin. Notice the very large ground bus in the illustration above.
How should a lightning protection System (RBS) be formed?
The earthing network of an RBS should be formed by a ring loop surrounding the tower, equipment room and fence, at a minimum. The mean radius re of this ring loop should be not less than l1, as indicated in Figure 1 and this value depends on the lightning protection system (LPS) class and on the soil resistivity.
