Research on Equipotential Earthing Optimization Bonding in Radio Base Station

Earthing is the foundation of lightning protection of the RBS (radio base station), providing a way for discharging the lightning current. Equipotential bonding can protect equipment from lightning attack, providing a potential reference point for all equipment. There are two methods for the equipotential bonding. The first is the constant bonding, that is, equipment are grounded directly through earthing wire and the other is the instant bonding which should be used for the earthing through SPD (Surge Protective Devices). The paper will discuss the implementation problems on equipotential bonding of the RBSs. Keywords—Earthing, Equipotential, Optimization, Bonding I. SUMMARY For the lightning protection of RBS, the problem of the equipotential bonding has always been talking about. The earthing of RBS is necessary and foundational. Till now, many technicians have only focused on the connection of devices which can be earthed directly; Some people mistakenly think SPD is not useful for they ignore an important issue: how to implement connection for many systems, such as power supply, signal ports that can not be earthed directly in the RBS.
