Ameren, 5kV Switchgear Replacement
St. Louis, Missouri
The existing service switchgear was replaced at the electric utility’s St. Louis headquarters. The new switchgear has two mains (preferred and alternate) with automatic and manual throw-over, metering, 5kV feeder breakers, 5kV feeder work, and 120 volt DC control power. Numerous existing substations were served by this switchgear and had to be reconnected. A short circuit, coordination, arc flash study and a detailed phasing schedule was included.
