the case of a com-pound generator, the serieswinding may be so con-nected as to produce amagnetizing effect thataids the shunt field, andwith an increase in loadthere is an increase mtotal field excitation. If this increase in field excitation is just sufficient to main-tain the terminal voltage… … Load Current Fig. 154 THE DIRECT-CUERENT GENERATOR 189 Increase in load the machine is said to be under-compounded.The external characteristic curve of an over-compounded gen-erator is shown by curve (A) ii.
