al to E, and the switchS is closed. The load on B is then zero. To make the twomachines divide the load, the excitation of B is increased so as toincrease its generated voltage and thereby cause the machine todeliver current to the mains. If, due to a momentary increase in speed or for some other… … Fig. 179. —Loading back test ona generator. Art. 195] OPERATION OF GENERATORS 165 the higher voltage at that instant. Furthermore, if the engineconnected to B fails for an instant, that machine slows down, itsgenerated voltage drops and the load is automatically thrown onA; if this generated…
