Weight, especially nonlinear load is larger and when generating set capacity is smaller this harm just become apparent from, it is main when unit is with UPS
Show following several phenomenons：
（1）The output voltage of generating set increases suddenly, causes UPS to damage.
（2）Generating set output frequency causes UPS protection acts to 50~60Hz.
（3）There is serious mechanical resonance phenomenon while the frequency of occurrences or electric voltage exception in generating set, and oil machine occurs
Rhythmical wave rises and falls with sound, also occurs the energized circuit and AVR that damage generator when serious（Automatic voltage regulator）.
（4）UPS automatically shuts down rectifier because detecting overvoltage or overfrequency, from backup battery group to load discharge or
Directly powered to the load from bypass.
