tes a Bullock three-wire balancer set. The action of the balancer is complex, and a full explanationis not desirable here. In general terms, however, it may be statedthat when there is no current in the middle wire of a three-wiresystem the current through the balancer armatures is only enoughto… … Fig. 41. Current through Balancer Set. 50 DIRECT-CURRENT MOTORS power. This is illustrated in Fig. 41, where one outer wire carries100 amperes, the middle wire 20 amperes, and the other outer wire80 amperes. If the balancers are equal, and there are no losses, the20 amperes divide equally between…
