Abstract :
In the body of the paper by Fortescue and Wagner, presented at the recent Midwinter Convention, and in the companion papers by Evans and Bergvall, E. B. Shand, and Evans and Sels the conditions of stability are discussed by means of graphs. This method has been chosen as that best fitted for presenting these important factors in the problem of power transmission before the engineering public in the form best adapted for practical application.
