Capacity Increase and Feeder Upgrade


January 2016 – August 2016

The scope of the project was to replace the existing 72-25 kV 5 MVA transformer with a 72-25 kV 11/25 MVA transformer. It also required station upgrade of the metering, upgrading the feeder protection controllers and the addition of a remote monitoring and control system. This project is a great example of using engineering to combine new technologies and equipment with existing.
