4. Lineage Power - Total Efficiency TM 4 © 2009 Lineage Power Losses Typical AC installations engineered to trade copper cost against losses - 3% Voltage drop in the ac loop - Gives 3% power loss with 3Ø 480Vac rectifiers, 5.9% loss with 1 Ø 240Vac DC Losses from engineered cable resistance, trading cable cost for loss Centralized Architecture - Rectifier to load – 3.9V drop in cable and distribution - Possible 7.4% Power loss Lineage Hybrid Architecture reduces the DC losses by 60% 270KW Example Centralized Architecture 5,000A Load Current Engineered voltage drop – Up to 3.9V 3.9V x 5,000A = 19.5kW losses = $17,082 LOST / yr @10c/KWh Lost Energy is heat – Additional HVAC cost ~ $5,000 / yr 270KW Example Hybrid Architecture DC Distribution (VI) losses reduced to loop of <1.0V from 3.9V Losses now 1.0V x 5,000A = 5.0KW SAVINGS: 19.5KW -5.0KW = 14.5KW = $12,702 / yr @10c/KWh HVAC Savings: Approximately $4,000 Total Savings: $16,702
