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.
The most important objective of the radio base station (RBS) earthing network is to minimize the differences in potential between the conductive parts within the RBS site (equipotential bonding), which is beneficial for the safety, lightning protection and electromagnetic compatibility (EMC) performance of the equipment.
The study results show that for the improved protection of the primary system against lightning, the total power grid must be considered as a source of improvement for studying shielding influence and the protection levels provided inside this substation.
In this study, a 110 kV substation is designed, and the lightning voltage and current, and the LPS protection of the substation during a thunderstorm are calculated. The designed LPS results in the reduced impact of lightning disturbances and improved robustness of the grid substation.
