An illustration from Electrical machinery; a practical study course on installation, operation and maintenance, 1921, leaf 222
t the voltage atthe armature terminals, 107 volts, gives point b on the curve.Increasing the load to 90 amperes will cause the voltage todrop accordingly, or, as shown at point c on the curve, to be105.5. Now, if the load is further increased, a correspondingdecrease in voltage is obtained.… … Fig. 225 Fig. 226 Fig. 227 Figs. 223 to 227.—Diagrams of shunt-connected and series-connected generators. What actually happens in a shunt generator is that thevoltage decreases as the current is increased up to a certainvalue and then both volts and current decrease to zero orapproximately so.…
