Phase Balancing: The Last Few Inches Of a High-Efficiency Power System

Click here for the full white paper

White Paper Summary
Within enterprise data centers, the power used for operating the facility, lighting, running IT loads and cooling is the largest operational expense. With large data centers operating in the tens of megawatts, incremental increases in efficiency translate into appreciable savings. This paper discusses the effect on efficiency of load balancing across phases in a 3-phase distribution system.

Though it is well known that an attempt should be made to balance loads in a 3-phase system, losses attributed to the failure to balance are not typically discussed. Higher efficiency leads to better utilization of your available power, and thus operational cost savings.  As amperage delivered to the data center cabinet continues to increase from 30A to 60A to 100A+, losses in the feeder wiring should be considered. 

Discover what the efficiency loss in your data center may be if your 3-Phase power is imbalanced.  For more, click here.

DatacenterDynamics - Washington DC
August 31st
With President Barack Obama's recent memo endorsing Federal CIO Vivek Kundra's plans for government data centers, the race is on to submit final data center consolidation plans to the Office of Management and Budget for approval by August 30th.

But what happens in the meantime? Looking forward, how will government agencies balance the requirement for consolidation with current operational needs and existing plans for infrastructure upgrades without risking service disruption?. Register to attend today.
