BACK SPAN CONCERNS This discussion has focused only on the main span. Vibration of conductors such as experienced on this crossing is not limited to a single span. The motions are fed through the suspension clamps to the adjacent span that...

AI summary The discussion highlights concerns regarding the vibration of conductors on the new Canso Strait 230 kV crossing, emphasizing the need to inspect back spans and adjacent structures for damage. It also critiques Salvi's new damping scheme for being insufficient in frequency range and suggests using airflow spoilers from the old crossing for better protection.

in the original engineering design. The existing vibration control dampers had experienced fatigue-related deterioration and were no longer providing adequate long-term protection for the conductors. NS Power retained external experts to a...

AI summary NS Power identified deterioration in vibration control dampers on the L7005 transmission line, leading to potential conductor damage. External experts recommended mitigation measures, which NS Power implemented between 2022 and 2024. The Board recognizes L7005 as a critical asset, with conductor failure posing public safety risks and disrupting power flow through a key transmission corridor.
