8kW gasoline generator TO9000ETGasoline generator in calibration.At ambient temperature, engine oil should have good fluidity.At temperature, it is particularly important for air-cooled gasoline engines to have appropriate kinematic viscosity. When the generator is at rated no-load voltage, add an equivalent25%Three phase symmetrical load with rated power (functional factor)conФ＝0.8Lag), and then add to any phase25%A resistive load with rated power that can operate for a long time, at which point the three-phase line voltage.Value（.The difference between the small value and the average three-phase line voltage is not greater than the average three-phase line voltage5％。
