This new technology helps a building become electrically invisible to lightning. UPS - Delta evaluated several small UPS units to support computers at gates and other customer service sites. The application requires a small footprint, long battery uptime, and serviceability. Exide's OneUPS Plus 300 UPS units across the country wherever Delta flights are scheduled. The Home Depot's data center processes sales for hundreds of stores and functions as a zero downtime facility.
High uptime requires highly reliable electrical and mechanical systems.
Using the parallel redundant UPS units already in place, PTG installed a 750kW Standby Power Generator in case of a long term utility power outage. PTG was challenged with avoiding single points of failure, minimizing downtime during the buildout, and achieving a seamless power transfer from UPS to generator power. Each switch transfers the load from the UPS to the generator sequentially, softening the application of the load to the generator. This method stabilizes the generator and protects the UPS and computers. Site Monitoring System - Information system availability depends on functioning foundation equipment like UPSs, generators, cooling towers, and air handlers.
