Research on equipotential bonding of 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.
