| Conformance assessment of radio base stations regarding lightning protection and earthing |
 |
This Recommendation provides the technical requirements and measurement methods to assess the validity and reliability of the lightning protection and earthing system of radio base stations (RBSs). It focuses on the quality control in the process of construction, acceptance, inspection and maintenance.
Normally, the conformance assessment is carried out during and immediately after the construction period and it results in the commissioning of the installation to start its operation. Routine inspections are scheduled in order to assure the maintenance of the lightning protection and earthing characteristics, during the operation life of the installation.
Depending on the function and installation location, the lightning protection system of a RBS can be partitioned into 4 parts which consist of air-termination and down conductor system, earthing system, equipotential bonding network and surge protective devices (SPDs). The conformance assessment is directed to these parts, and may consist in visual inspection, measurement, analysis and other applicable methods.
The assessment requirements of each part for commissioning and routine inspections are presented in Clause 8 to 11 separately. In addition, management rules are introduced in Clause 12, which are effective for conformance maintenance during the operation life of the RBS.
