HH Angus provided electrical engineering for a 50,000 ft2 raised floor computer area serviced by redundant feeds from the existing 27.6kV distribution to redundant 600V distribution systems. Four 2 MW parallel synchronized diesel generators with capacity to increase to six; two systems of four redundant 750 kVA UPS modules; and state-of-the-art life safety, alarm monitoring, and security systems.

Recent upgrades to the facility include the installation of two 3000A Static switches to the two parallel redundant 750kVA UPS systems, configured to not only permit seamless transfer of critical loads between utility and emergency power in the event one UPS system fails, but also to permit seamless transfer to the surviving UPS system.  HH Angus has functioned as Prime Consultant and Electrical Engineer for a series of reports, studies, distribution upgrades and raised floor expansions at the site.
