Shunt excited generator
WebTo learn how to connect both the compound and the differential compound generators. To obtain the armature voltage vs armature current load curves for both generators. DISCUSSION. Self-excited shunt generators have the disadvantage in that changes in their load current from no-load cause their output voltage to change also. WebSignificance of Saturation in Self-Excited DC Generator Saturation makes the voltage buildup in the self-excited shunt DC generator feasible. Suppose the armature voltage was linear with the field current, as shown by the heavy solid line in Figure 3. The field circuit equation also is a straight line.
