Project: T173700 #3272

The objective of this study will be to create an industry best practices guide and decision tree through the identification of practical solutions for maintaining transmission line clearances which improve safety, reliability and compliance while reducing total cost of transmission operations. All types of activities which contribute to maintaining transmission line asset management compliance will be considered such as ground patrols and inspections, aerial patrols etc. in the evaluation. However, particular attention will be paid to the use and benefit of remote sensing as it applies to achieving these objectives. The study will include an analysis of optimal return frequency intervals for data recapture and analysis as well as a comparison of various technologies such as LiDAR vs PhoDAR in terms ofaccuracy, price and value. The study will also describe how the recommended frequency and type of data capture can benefit the transmission line asset management verticals described above.
