The plan which has beenused satisfactorily in our recent equipments is t use a gener-ator with an automatically drooping characteristic obtained byputting a differential -cries field cither on the generator or onthe exciter. Curve No. 3 of Figure No. 1 shows the character-istic of such a generator and Figure No. :! shows the cor-responding scheme of connections. Theoretically such an equip-ment dots not load the engine through as great a range as can Serieseld. iGovemor enerator
