The Naval Surface Warfare Center Dahlgren Division, Dahlgren Laboratory is a premier research and development center that serves as a specialty site for weapon system integration. J.E. Richards, Inc. performed this electrical installation with careful coordination with our client and the facility. The power distribution consists of (2) 13.8KV transformers, (2) 3000A switchboards, (1) 800A Motor Control Center, Approx. (60) distribution panels with (5) different power sources being transformed in the building: 120/208V 60 Hertz, 277/480V 60 Hertz, 440V 60 Hertz, 440V 400 Hertz, 115V 400 Hertz, which are all used to simulate/test equipment used on Naval ships and submarines.
The challenge was intercepting the existing 13.8KV feeders in order to install new four way switching and three new transformers to serve the surrounding existing buildings and the new facility while maintaining uninterrupted operations at the base.
Panels are distributed throughout the facility as well as labs on the 1st floor. Navy personnel will utilize for various equipment to test, maintain and return to the fleet. The facility will also house Navy Administrative Staff on the 2nd floor.
J.E. Richards, Inc. was recognized by The Washington Building Congress with an Award for Outstanding Craftsmanship for Power Distribution.
