ing T and t\ is then equal to r2, i\ isequal to i2, diagram A, and no current flows in the coil F, so thatthe exciter voltage and the booster voltage are both zero. If the generator load increases, the pull on r\ increases and itsresistance decreases and is now less than r2 so that i\… … 0 1 2 3 4 5 6 78 9 10 Minutes Fig. 197.—Load curves on the power house of a steel mill.
