Moroni Communication Green Base Station Lightning Protection

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.

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.

Is a telecommunication tower impacted by lightning?

If the antenna is installed on the top of telecommunication tower, e.g., antenna positions 1 of Figure 29, it is considered to be impacted by or exposed to direct lightning strikes. Refer to [IEC 62305-3] for detail information about the protection angles and volume protected by an air termination system.

Can a navigation light monitoring unit be installed in a PDB?

Refer to [IEC 61643-12] for the relevant information. If the NL is directly powered by PDB in the equipment room, an SPD should be integrated into the PDB. The bonding conductor of the PDB is recommended to be shorter than 1 m. The protection module of the navigation light monitoring unit can be installed in the NLCB or in the PDB.
