115kV Breaker 12/16/20 MVA Substation

This substation was built to primarily to serve a large CO2 pumping station with a second feeder to serve the client’s future load in the area. Two deadend structures were provided, one for the substation and a second structure for using the mobile sub in emergencies. The transformer is rated at 12/16/20 MVA and 115kV/24.9kV. The switch structure on the low side allows the transformer to be disconnected and the lower set of single phase switches are provided for use with the mobile sub when needed. The station uses voltage regulators rather than LTC. The low voltage structure is the T&D vertical main and transfer design with disconnect switches to serve two feeders.
