What's New

• Generator Fuel Systems Affect Uptime
• 11 November, 2011
• Whether for a data center, health-care building or 911 call center, a great deal of time and effort are put into the design of the emergency backup generators, switch gear and UPS equipment that supply emergency backup power. Often very little attention is given to the design of the fuel oil supply system necessary to run the generators. A badly designed fueld system can cause a power interuption just as certainly as a failure of the the downstream equipment.

• Diesel Generator Failures: Lessons Taught by Hurricanes
• 09 November, 2011
• Understanding the reasons generators failed during recent hurricanes and applying some of the lessons learned may help ease future emergencies.
