The example of calculating the excitationfield at no-load for a large turbogenerator shows that the advantages of arc elements are highly accurate and easy to use.

The effect on the generator excitation magnetic field is different when the capacity and power factor of load are different, and the effect on the internal impedance voltage drop is different, too.
In the high tension field, the excitation and ionization of particles on the fuel drop surface only need the lower cylinder temperature to realize the better second atomization.
