DESCRIPTION: This project is to rebuild the L-5046 tap at its intersection with L-5017, which is in the Wolfville, Annapolis Valley area. The tap structures and switches at this location were identified as requiring replacement as part of...
AI summary This project involves replacing 9 transmission structures and installing a new switch (83V-504) at the L-5046 tap in Wolfville, Annapolis Valley. The work is divided into two phases, aiming to enhance operational flexibility through on-load switching and a permanent bypass. Upgrades will improve transmission system reliability and isolation efficiency.
Why do this project? The equipment at the L-5046 and L-5017 tap, as well as the 83V-504 switch are degraded. The assessed condition of these assets, as determined through NS Power's transmission line inspection program, was found to be det...
AI summary The L-5046 and L-5017 tap equipment, along with the 83V-504 switch, are degraded and require replacement to prevent outages affecting 5,500 customers. Upgrading the switch will enable live line operations, reducing disruptions during maintenance and future construction.
Why do this project now? This work has been prioritized based on the condition of the transmission line assets as determined through NS Power's transmission line inspection program results, as well as the criticality of the line to the ove...
AI summary This project is urgently needed to replace deteriorating transmission line structures and switchgear serving 5,500 customers, preventing unplanned outages and enhancing system reliability. Design changes aim to eliminate outage risks during switching and address vehicular access issues, emphasizing the criticality of timely infrastructure upgrades.
Why do this project this way? The existing location of the switches has posed serious safety issues when accessing the location during winter conditions, impeding access that is required for operation and maintenance of the existing switch...
AI summary The project relocates switches to a roadside location to address winter access safety issues, enabling live line switching and eliminating customer outages during maintenance. The original site was deemed infeasible due to accessibility challenges, prompting the shift to a more efficient location for maintenance and faster restoration.
