ioo SYNCHRONOUS ALTERNATORS. [Exp. 



unless, in addition, the resistance drop is separately stated. Tests at 

 zero power factor are also objected to because such tests are made 

 when the distorting influence of cross-magnetization is absent. (See 

 Vol. I., p. 761, Int. Elec. Cong., 1904.) 



55. References. References are given below to a few leading 

 articles on the subject of alternator regulation. A complete list would 

 be a long one, but the references here given are the best ones to consult 

 first; they contain references to practically all that has been written 

 on the subject. Rushmore's paper, with twenty-four references, sum- 

 marizes the work of others and is one of the best papers to read first, 

 particularly in connection with variations of the magnetomotive force 

 and electromotive force methods. The discussion, found at the close 

 of some of these papers, will be found very valuable.
