Power Line Structural Assessment
Engineering models of transmission line routes provide a convenient method of analyzing the effect of different loading scenarios on transmission networks. Network Mapping has powerline expertise, ready and able to model networks from level 1 (stick towers) through to level 4 (full structural models). Analysis of loading events identifies failing and critical members.
Network Mapping can provide a schedule of replacement members, using optimisation tools to find the most appropriate replacement members for any steelwork experiencing overstress.
The engineering model allows for the modelling of many loading scenarios, such as heavy ice and high wind. As well as identifying overstress in the steel members we can calculate the footing reactions at each tower. This site-specific foundation design can reduce the amount of concrete required for the footings by anything up to 50%. As well as the significant cost advantages, the reduction in materials required and the reduced number of vehicle movements can make for a major environmental benefit.
The LiDAR survey of the transmission line route provides XYZ point data and photography of the proposed line route. Our powerline experts model the line route to precisely replicate the 'as erected' behavior of the transmission line. The studies of structural capacity can be performed for the existing conductor system, or alternative conductor systems can be readily appraised.
