hexagon in-scribed in a circle whose diam-eter is equal to the effectivevoltage across the rings of asingle-phase rotary. Measuredin terms of the d. c. voltage, wehave shown that V^ equalsEac X .354. In the dotted triangle 1-3-5it will be noted the lines 1-3,3-5, or 5-1 represent the voltagebetween… … Fig. 16. Relation of A. C. Voltages ina Six-Phase Rotary Converter 148 MANAGEMENT OF DYNAMO-ELECTRIC MACHINERY 27 will be seen to be equal to diameters of the circle. Therefore thesame relation exists as for a .single-phase rotary. Thus thealternating-current voltage across rings 1 and J^, 2 and 5,…
