Outside Right-of-Way Tree Risk Along Electrical Transmission Lines

By: Siegfried Guggenmoos

Abstract - For power transmission systems compliant with safety codes and reliability standards there remains a risk of tree-caused interruptions from the in-fall of trees from outside the right-of-way. This paper reports on the quantification of tree exposure outside National Grid’s transmission corridors and examines the variables impacting the risk of a line contact by trees
