Y or star scheme of connectingthe three windings or phases A, B, and C. Another scheme for connecting the three windings A, B, andC (also for balanced loads),called the A (delta) or meshscheme, is illustrated in Fig. 128.Winding (or phase) A is connect-ed between rings 3 and 1; wind-ing (or phase)… … Fig. 12t). Collector Ring System for Three-Phase Alternator 135 124 ALTERNATING-CURRENT MACHINERY is called the positive direction through the circuit. This directionis chosen arbitrarily. The arrows in Figs. 127 and 128 indicate thepositive directions in the mains and through the windings. It…
