During the last few decades, a large number of lightning related accidents and damages have been reported in many countries in connection with communication and broadcasting tower sites ( Kithil, 2006, Eriksson and Meal, 1984, Pierce, 1971 ). In a tower environment, lightning related hazards may occur at various stages of a lightning strike. a.
The lightning current will most probably enter the cables connected to the object struck, and flow into the signal feeding devices or power panels in the base transmission station (BTS) causing many other hazards to both equipment and staff. b.
Planning the management of lightning at a communication tower site should be done together with overall safety planning and the lightning safety procedures should be integrated with the master safety guidelines. A stepwise guidance for addressing the lightning safety issue is given below.
The general concepts of protection of structures and equipment against lightning have been covered in IEC 62305 1-4, 2006, American Standards NFPA, 2008, IEEE C62.41, 1999 and AS/NZS 1768:2007 (2007), etc.
Based on our observations we make a comprehensive list of recommendations for the installation of lightning protection scheme at a tower site and also discuss a concrete encased steel reinforcement system that can be used as a suitable grounding system for sites with very high soil resistivity.
In the 48 sites that we have investigated, there were 102 occasions of damage to the equipment in the base transceiver station (BTS) at 27 tower site and 13 cases of personal injuries at 08 sites. The exact nature of damages is highly complicated to analyze.
