Wireless sites demand a low impedance lightning protection, bonding and grounding system to maintain critically important up-times. Since 1960, Harger has provided the best structural lightning protection, bonding, and grounding for commercial applications.
The earthing and lightning protection systems are to be installed indoors and outdoors in electrically exposed locations, less than 1,000 metres above sea-level. The maximum wind (gust) velocity is 50 metres per second. The humidity is high and the atmosphere is often salt-laden.
In the earthing system for a single wireless base station, the earthing network, down-conductors and metal conductors make a test loop. By using a clamp meter, the earthing resistance of the entire loop can be measured, but not the earthing resistance of the earthing network.
The indoor earthing bar and the power distribution box (PDB) are installed close to the feeder panel. The PDB has SPDs connected between the power conductors and the earthing bar. The indoor earthing bar is provided for the bonding connection of the PDB and all the equipment inside the equipment room.
Bases and steel support structures shall be connected to the grid by a single connection, unless these form part of primary equipment support in which case a double connection shall be applied. Steel towers, including the individual towers of portal structures shall be connected to the substation earth grid by double connection.
Also, special features of combining overvoltage protection devices with SMA inverters are described. The document covers lightning protection in as far as it influences overvoltage protection. Lightning protection systems are intended to prevent damage to buildings from lightning strikes.
