ABSTRACT: The purpose of this proposal is to demonstrate the feasibility of reducing fuel consumption by efficiently providing single phase 120VAC power distribution that is automatically load balanced over existing 240VAC three phase generator produced power. This device, coined the Automatic Load Balancing Device (ALBD), will supply single phase 120VAC for distribution within Forward Operating Bases (FOB) and mitigate the majority of generator small load overcompensation. The proposed ALBD device will provide a method to spread or balance the single phase 120VAC load across all three phases of the generator three phase outputs equally without modification to existing generators or infrastructure. The effect of this balancing will minimize the normal generator reaction to increase RPM since the load is spread and the voltage drop will be divided. BENEFIT: The most obvious benefit to the development of the ALBD is the immediate reduction in FOB fuel consumption. No less important are generator maintenance issues especially related to engine wet stacking caused by no load high speed operation.
