PHASE B I 545.—Diagram of two phase mesh grouping. Ques. How is the two phase mesh connection arranged ? Ans. In this style of grouping, the two phases are divided CONSTR UCTION OF AL TERN A TORS 1,245 into two parts, and the four parts are connected up in cyclicorder, the end of one to the beginning of the next, so as to form asquare, the four corners of which are connected to the fourterminals a, b, a , b, as shown in fig. 1,545, or in the case ofrevolving armatures, to four slip rings. Ques. Describe a three phase star connection? Ans. In three phase star grouping, one end of each of thethree circuits is brought to a common junction M, usually. PlG. 1,546.—Diagram of three phase star grouping, commonly called Y grouping owing to itsresemblance of the letter Y. The current in each main is obviously equal to the currentin each phase winding, but the terminal pressure is the vector sum of the pressures in thecomponent phase windings, that is, V3 multiplied by the pressure in one phase. insulated, and the three other ends are connected to threeterminals a, b, c, as shown in fig. 1,546, or in the case of revolvingarmatures to three slip rings. Ques. What other name is given to this connection,and why? Ans. It is commonly called a Y connection or groupingowing to the resemblance of its diagrammatic representationto the letter Y. - ha: \ectricity F*i. 1-547.—Radial <Ka-
