High Banks Series Capacitor Bank Station

The High Banks Series Capacitor Bank Station was a project to support adding additional generation to an existing transmission line. The intent of this project was to add a series capacitor bank to the middle of a transmission line. The scope of work included everything except the design of the capacitor bank platforms. My role in this project was related to the electrical and physical design and included collaboration with the capacitor bank manufacturer. One highlight of the project was representing the substation EOR at the capacitor bank FAT testing.
