With respect to phase balance -- or lack thereof, if one phase is much higher than the others (for example 75, 100, 75) the total power according to my generator's display is 46 kW, but would the diesel engine be loaded more? Maybe as if they were all 100 A, trying to spin and make the force required for largest magnetic field? (I'm not sure if my terminology is correct), or is it an average of them? Or root? Or something else?
The goal is to quantify the energy (fuel) being wasted (or not) by unbalanced loads on my generator. I'm not necessarily looking for an all encompassing equation to calculate the exact kW of power the engine output needs to produce 46 kW of electrical power given the unbalanced phases condition, but I would like to understand the major variables' proportional effect on the power required to make more power. ;-)
