d. Generators for lighting and power service are generally flat-compound machines wound for 125 or for 250 volts. For railwayservice the generators are overcompounded so as to maintain thetrolley voltage at some distance from the power house. Streetrailway generators are invariably wound for 600… … Line Current la Fig. 100.—Regulation curve of a series generator. in a series generator would be if armature resistance and armaturereaction were negligible; the voltage would increase with the loadcurrent since this is also the exciting current. Curve A is reallythe no-load saturation curve of the…
