6 FAQs about Solar Base station power supply first level lightning protection

What is a lightning protection system (LPS)?

3.2.3 lightning protection system (LPS): Complete system used to reduce physical damage due to lightning flashes to a structure. NOTE – An LPS consists of both external and internal lightning protection system.

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.

Where should a Class I surge protection diagram be installed?

The Class I SPD should be installed in the main PDB. The building owner is responsible for the installation of the Class I SPD of the building. The 3+1 type surge protection diagram is recommended for three-phase AC power supply systems, as shown in Figure 25.

What is a radio base station (RBS) earthing network?

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.

How to protect the navigation light system in the equipment room?
