In actual operation, the shielding failure rate of UHV transmission line is much higher than that in simulation, so it is crucial to study the lightning shielding performance by experimental research. The testing UHV transmission line model is scaled down in the ratio of 12.5 which is relatively large comparing to other testing models. Two kinds of negative switching impulse waveform were applied...
This paper explains lightning protection and earthing issues of RBS (radio base station) and discusses people's cognitive process to RBS's attack by lightning through four processes of Jiangmen (Guangdong Province of China) RBS's lightning protection and earthing transformation. This paper proposes the key to solve RBS's lightning protection and earthing questions qualitatively and quantitatively...
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...
