This means less performance andtherefore a reduced power exploitation. As soon as temperatures increase, anengine runs less economically and electrical components have more resistance.For every 500 meters above high altitudes of 1000 meters above sea level, theperformance of the generator is reduced by 3%. For outside temperatures above40 degrees Celsius, the generator performance is reduced by 3% for everyadditional 5 degrees. The tables shown help with the high altitude and outsidetemperature performance devaluation. In order to determine the true generatorperformance, it may be necessary to consider both the high altitude andtemperature devaluation factors.
