In order to improve the reliability of one of the State’s data centers, a redundant backup generator was needed. Puckett Engineering provided the design, construction admin, and commissioning. Puckett Engineering’s solutions began with an assessment of the existing emergency power system to determine the best way to incorporate a redundant generator. The resultant solutions included a 2000 kW generator, Generator-to-Generator Bypass-Isolation Transfer Switch system, surge protection for power and low-voltage systems, and monitoring via the building management system and remote annunciator. The emergency power system was fully tested in order to confirm proper operation and monitoring of the generators and transfer switch system, including various scenarios for both normal and fault conditions.
