Consumer A buys Generator B. ;)

1.Generator is rated at 10Kw at 88 amps (60 Hz) spinning at 1800 rpm.

Power One-Phase

Load Amperage at 120 volts ---

Maximum Load 88 Amps

Continous Load 83 Amps

Load Amperage at 240 volts ---

Maximum Load 44 Amps

Continous Load 42 Amps

Fuel used

Consumption at 0 load .35 gallons/hour

Consumption at 1/2 load 0.55 gallons/hour

Consumption at 3/4 load 0.76 gallons/hour

Consumption at full load load 0.94 gallons/hour

Customer A finds that the Generator is generally under no load most of the time, therefore decides to lower the rpm to 800.

Fuel used at this rpm at almost 0 load = .08 gallons per hour.

Problem is that at 800 rpm, voltage drops to about 32 volts at 27 Hz.

Goal: maintain 120 volts and 60 Hz if possible at 800 rpm under no load. As rpms increase I want to maintain voltage until its reaches its rated 1800 rpm where everything is gravy.

Ideas? Suggestiongs?
