Dept. of TransportationUS Transportation CollectionThe goal of this project was to collect the knowledge needed for the FDOT to either confirm orimprove the adequacy of the FDOT\ue2\u20ac\u2122s existing minimum standards for lightning/surge protection,including devices used and installation procedures. The project was conducted in four (4) tasks:\uef\u201a\ub7 Task 1: State of the Practice/Best Practice Study and Literature Search\uef\u201a\ub7 Task 2: Review of the IEEE Recommended Impulse\uef\u201a\ub7 Task 3: Review of the Effectiveness of Lightning Termination Devices\uef\u201a\ub7 Task 4: Final Report.The research conducted for this project included surveys of FDOT districts and other state DOTswith similar lightning environments, literature searches to determine the proper techniques to test surgeprotective devices (SPDs) and best practice in designing lightning protection systems, design andconstruction of an SPD test laboratory, and analyses of NFPA 780 and other related standards with respectto the most appropriate standards to employ in designing lightning protection systems for FDOT roadsideequipment.The results from this project included equipment and test procedures for an SPD test laboratory,recommendations for improved maintenance reporting to improve identification of lightning-relateddamage, and lightning protection system design recommendations. Implementing theserecommendations will reduce the FDOT maintenance costs and improve the reliability of intelligenttransportation system (ITS), traffic control, and roadway lighting equipment
