Transient fault Currents in Aircraft D-C Systems
Abstract
Two simultaneous differential equations have been derived which satisfactorily describe the transient fault current in a shunt-wound aircraft d-c generator in terms of easily obtainable parameters. Improved accuracy of the result is attributed to eliminating the assumption of constant field flux linkages during the transient and substituting the assumption of constant rates of change of field flux linkages with armature and field currents. The field flux leakage coefficient was assumed constant. Theoretical and empirical transients compared favorably for both separately and self-excited generators. The effect of a carbon-pile voltage regulator was successfully predicted. Transient resistance has been redefined in such a manner that its value can be predicted in terms of the physical parameters of the generator.
