Undersome conditions, many considered normal, agenerating set could fall short of the requirements ifcertain operating FACTORS are overlooked. Readthrough the bulletin and follow the examples onselecting a GENERATING AFFECTING GENERATING SETOUTPUTE ngine power and generator capabilities determineoutput of a GENERATING set. A main factor affectingoutput is the ratio of engine power to power requiredby the generator. Engines with considerable reservehorsepower are only slightly affected by a small lossof engine efficiency. If the engine must operate nearits maximum rated power output, any engine powerloss will also result with a generator output the variable FACTORS affecting GENERATING setoutput is- Fuel High Altitude High Ambient TemperatureIf anyone condition affects engine power enough, therating of the GENERATING set has to be lowered or"derated.
