| Risk assessment of damages to telecommunication sites due to lightning discharges |
 |
This Recommendation gives support to protection engineers in evaluating the risk for severe damages caused by lightning. It comprises a risk analysis that includes the effect from direct and nearby lightning strikes as well as overvoltages originating from incoming services, mainly power and communication networks. The analysis also indicates the most efficient additional protective measures for sites with insufficient basic protection.Part of this Recommendation deals with the risk of injuries to people being present at the site during thunderstorms.This Recommendation is based on a concept from IEC TC 81 and modified to be applicable to practical cases in telecommunication systems.The example in Appendix I applies to a telecommunication site with an adjacent antenna mast. |
