  • Regeneration of power with single-phase electric railway motors

    Publication Year: 1907, Page(s):1233 - 1244
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2520 KB)

    The conditions necessary in order that an electric motor may operate successfully in regenerating or restoring power to the supply circuit are: 1. The counter pressure generated by the motor must be greater than the impressed pressure of the supply circuit. 2. The value of this excess counter pressure must be under control and maintained in suitable relation to the impressed pressure. 3. There mus... View full abstract»

    For several years past some of our large manufacturers have used fractional pitch windings, for induction motors to a considerable extent, and for alternators to a lesser extent. View full abstract»

  • Commutating-pole direct-current railway motors

    Publication Year: 1907, Page(s):1265 - 1275

    General. In order to appreciate the development and reasons for the existence of a commutating-pole railway motor, it is well to discuss in some degree some other developments. In the beginning, railway-motor designers had many difficulties to contend with. View full abstract»

    Railroads signals may be divided into three general classes according to their functions: (a) Those which confer rights on trains, or restrict their rights, known as train-order signals; (b) Those which designate the route a train is to take, and insure the safe condition of all switches and opposing signals on such route known as interlocking signals; (c) Those which are used primarily for proper...

  • Discussion on “some facts and problems bearing on electric trunk-line operation,” at New York, May 21, 1907

    There are so many points on which I fully agree with Mr. Sprague that it is perhaps well at the outset to dwell on one matter where we appear to disagree, and that is the relation of those engaged in the conducting of trunk-line railroad operation to the electrical engineering profession which is now gazing with hungry eyes on that enticing field of new endeavor — the electrification of tru...

  • Discussion on “lightning phenomena in electric circuits”, “protection against lightning, and the multigap lightning-arrester”, and “new principles in the design of lightning-arresters”, at New York, March 29, 1907

    Dr. Steinmetz gives a clear description and classification of the lightning phenomena that aid us greatly in understanding the problems and the methods proposed for meeting them. They are, however, the simple problems; there is yet to discuss what occurs when two sets of waves started from different points on a long transmission line eventually come together. Aside from the increased constants (ca... View full abstract»

  • High-voltage direct-current and alternating-current systems for interurban railways

    Publication Year: 1907, Page(s):1353 - 1366
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1446 KB)

    The magnitude and direction of engineering development in apparatus for the electrical equipment of high-speed interurban railways is well illustrated by a study of the systems adopted by some of the more important lines recently built or now under construction. These systems may be divided into three classes, namely: 1. 600-volt, direct-current using either overhead trolley or third-rail. 2. 1200... View full abstract»
