Discussion on “three-phase traction”

The presentation of this paper was prompted by the development, in the course of an investigation, of certain facts which indicated that the disadvantages of the three-phase motor for traction purposes had been very largely exaggerated, and its advantages either underestimated or overlooked. To present, in concrete form, a few of the points raised, it seemed desirable to take a specific case, and therefore that was chosen which is already familiar to the Institute, through the medium of Mr. Berg´s paper read some years ago.
