System keeps 'Net portal open
Article Abstract:
Internet search engine Excite's new backup power system is made up of two 1,250-kw generator sets, to provide emergency power and redundancy. Excite also has an uninterruptible power supply (UPS) to supply electricity while the gensets come up to speed. The gensets were designed as a paralleled system that start up when the UPS takes over during a power outage. The active generator will continue running for 15 minutes before the transfer switches go back to the outside supply when normal power resumes.
