Consumer A buys Generator B. ;)
1.Generator is rated at 10Kw at 88 amps (60 Hz) spinning at 1800 rpm.
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
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.
