I have diesel generator and when I loaded it up to 400 KW trip due to low ferquncy in which its total load 905 KW after I check up , I think that because fuel is not increase to feed injuction pump so that I want to know how actuator working ?
By the revolutions of the generator, or the (presuming AC output) frequency of the power generated. If the frequency is low, the revolutions are low. If the revolutions drop off when load is added, or frequency falls, you have a problem. somewhere.
