Abstract :
ECI and others have conducted applied practical research to the question of how trees cause sustained as well as momentary interruptions. This research has led to the development of a conceptual model of tree-initiated faults on overhead distribution systems. Information gained from this newfound understanding into distribution system construction, tree species, and voltage impacts on fault risk has implications for tree maintenance programs and construction standards. ECI has used this understanding to help utilities optimize maintenance cycles to reduce annual asset maintenance costs, while reducing interruptions associated with tree growth.
