DESCRIPTION: This project was for the replacement of the failed 67C-T64 transformer at the 67C Whycocomagh Substation. As the sole electrical supply for the Whycocomagh area, the existing 67C-T64 138–26.4 kV, 15/20/25 MVA transformer was r...
AI summary This project involved replacing a failed 67C-T64 transformer at the 67C Whycocomagh Substation with an equivalent unit from a future project to maintain service reliability. The failure was due to a non-repairable phase-to-phase fault, and a mobile transformer was temporarily used until the replacement was installed in October 2025.
Why do this project? 67C-T64 experienced an unexpected failure, leaving the substation without a permanent source of supply. The unit was assessed and determined to be beyond repair, making full replacement the only viable option to restor...
AI summary The 67C-T64 unit experienced an unexpected failure, rendering the substation without a permanent power supply. The unit was deemed beyond repair, necessitating full replacement to ensure long-term reliability and system integrity.
Why do this project now? 67C-T64 experienced an unexpected failure, leaving the substation without a permanent source of supply requiring immediate replacement. The replacement was prioritized because winter load was approaching and mobile...
AI summary The substation 67C-T64 failed unexpectedly, requiring immediate replacement to ensure a permanent power supply. The replacement was prioritized due to approaching winter load and the need for mobile transformer flexibility. The work was completed in October 2025 to ensure asset readiness for winter.
