  • The properties of electrons

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2647 KB)

    The physical properties of electrons form the basis of electrical engineering, and a thorough understanding of them is essential for successful investigation in some departments of research. No specific treatment of the subject has appeared in the printed publications of the Institute. It is therefore hoped that what follows will be of service to the membership. No attempt has been made to treat o... View full abstract»

  • Choke-coils versus extra insulation on the end-windings of transformers

    Publication Year: 1907, Page(s):685 - 688
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (418 KB)

    Surges along a transmission line are stopped and thrown back by choke-coils in a manner analogous to the reflection of water waves by a breakwater at the entrance to a harbor. The quiet of a harbor is obtained by setting up a strong wall capable of withstanding the shock of the waves that strike against it; so is the analogous quiet of a transformer obtained by placing a choke-coil in the path of ...

  • Protection of the internal insulation of a static transformer against high-frequency strains

    Publication Year: 1907, Page(s):689 - 694
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1390 KB)

    Most forms of lightning-arresters, especially of the multigap type, protect transformers against high-frequency even better than against low-frequency strains so far as these strains exist between either the high- or the low-potential windings, or between either of these windings and any other part of the transformer; because the high frequency causes a greater condenser charging current to flow a...

  • Transmission line towers and economical spans

    Publication Year: 1907, Page(s):695 - 711
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1260 KB)

    For any given transmission line there is a certain length of span which is most economical. A determination of what the economical span is, in any case, can only be made by obtaining data showing the variation of each item of cost which changes with the length of span. In a steel-tower line the cost of the tower is probably the most important among those items which vary with the length of span. A... View full abstract»

    The following is practically a summary of lightning trouble during the years 1904, 1905, and 1906, on a steel-tower, long-span transmission line in the states of Michoacán and Guanajuato, Mexico. View full abstract»

  • Location of broken insulators and other transmission line troubles

    Publication Year: 1907, Page(s):723 - 733
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1581 KB)

    Injury to a single insulator, under certain conditions of operation, renders an entire transmission line, many miles in length, entirely inoperative until the faulty insulator be discovered and replaced. The longer the line the more difficult it becomes to find a broken insulator, or to locate other irregularities in operating conditions, and a correspondingly long time is consumed in restoring th...

  • One-phase high-tension power transmission

    Publication Year: 1907, Page(s):735 - 741
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (579 KB)

    The recent advance in Europe of the Thury direct-current system of power transmission demonstrates the fact that unless an alternating-current system approaching it in simplicity of design and economy of material is developed, it is only a question of time before the high-tension direct current will gain a footing upon this continent. Consequently, the writer proposes a high-tension one-phase syst... View full abstract»

  • Some power transmission economics

    Publication Year: 1907, Page(s):743 - 757
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3606 KB)

    In designing power transmission systems, it is always well to bear in mind that the ultimate development of the art and of the country has not yet been reached. In the early days of railroading, the roads and equipment were not of the present trunk-line standard. Light rails, engines and cars, and unfenced right-of-way, and unballasted roadway sufficed. To construct at that time up to the present ... View full abstract»

  • The vector diagram of the compensated single-phase alternating-current motor

    Publication Year: 1907, Page(s):759 - 764
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (412 KB)

    Although the compensated single-phase motor is simply a series circuit in physical connection, there are incidental reactions which have the effect of a combination of series and parallel circuits. These reactions have an effect on the efficiency and power-factor of sufficient importance to warrant a careful analysis of their character and cause. View full abstract»

  • Inductive disturbances in telephone line

    Publication Year: 1907, Page(s):765 - 777
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (770 KB)

    The inductive action of one telephone line on another, producing what is commonly known as cross-talk, presents an important problem to the telephone engineer. The induction is both electromagnetic and electrostatic. A variable current passing through any circuit is accompanied by a variable magnetic field, which will produce electric currents in neighboring circuits. In addition to this there exi...
