    The object of this paper is to present in compact form the data and formulæ, together with their derivations, required for the determination of the mechanical and electric characteristics of transmission lines, together with a set of charts whereby the various mathematical operations involved may be accomplished rapidly and with the minimum effort. The treatment naturally falls under two he... View full abstract»

  • Transmission system of the Great Western power company

    Publication Year: 1911, Page(s):1417 - 1420
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (567 KB)

    The Great Western Power Company operates a long-distance, extra high-tension transmission system which extends from its hydroelectric plant at Big Bend, 16 miles north of Oroville, Cal., to Oakland, Cal. The nominal line voltage is 100,000, at 60 cycles. The length of the main line is 153.6 miles. A branch line 1.1 miles long taps the main line 136.5 miles from Big Bend. Both the main and branch l...

    Publication Year: 1911, Page(s):1425 - 1429
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (689 KB)

    The Great Falls Power Company is at present operating a total of 282 miles of transmission line at 100,000 volts. The principal transmission is from Great Falls to Butte, Montana, a distance of 130 miles. Over this distance two separate, single-circuit, tower lines are used, a single line being extended from Butte to Anaconda, a distance of 22 miles. View full abstract»

  • Some recent tests of oil circuit breakers

    Publication Year: 1911, Page(s):1431 - 1448
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4396 KB)

    Whenever an electrical circuit carrying considerable energy is opened in oil, gases are generated. These expand and rise, and tend to force the oil out of the containing vessel. They also form with air explosive mixtures, and either explode, or burn for a considerable length of time when ignited. It is important, therefore, that oil circuit breakers be provided with strong oil containing vessels i... View full abstract»

  • Development of the modern central station

    Publication Year: 1911, Page(s):1449 - 1461
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1444 KB)

    The predecessor of the huge modern central station is the Edison direct-current three-wire station, which was developed 20 years ago. By a system of feeders and mains, direct current was distributed at 220-volts from a station located at the center of power demand. When the limit of economical distribution from a single station was reached, additional stations were built, and all the stations conn... View full abstract»

  • The commercial loading of telephone circuits in the bell system

    Publication Year: 1911, Page(s):1463 - 1484
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3739 KB)

    The year 1900 may be considered to have marked the beginning of a very important period in the development of telephony. For some time prior to that date it had been known to those who gave study to the matter that the transmission efficiency of long telephone circuits would be improved by increasing the uniformly distributed inductance of the circuit. This knowledge, however, did not lead to any ... View full abstract»

  • The law of corona and the dielectric strength of air

    Publication Year: 1911, Page(s):1485 - 1561
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (9574 KB)

    For several years an extensive investigation on the dielectric strength of air, and more particularly, on the law of corona, has been carried on by the Consulting Department of the General Electric Company, under the general supervision of Dr. C. P. Steinmetz. The facilities were practically unlimited in regard to power, apparatus, instruments and their standardization, and available engineering s... View full abstract»

  • Automatic motor control for direct current motors

    Publication Year: 1911, Page(s):1563 - 1581

    “The flexibility of the electric motor”. is a well worn phrase and one which is quite commonly accepted at its face value. As a matter of fact an electric motor has quite definite characteristics, and these characteristics usually must be modified by some form of controller to adapt a given motor to various conditions.

  • Elevator control

    Publication Year: 1911, Page(s):1583 - 1603

    The elevator problem is really one of service, and the general character of the elevator equipment must depend upon the character of service to be rendered. The service to be rendered by an elevator depends upon the number of passengers carried and the number of floors served; and is limited by the time taken by passengers entering and leaving the car, and the time required for acceleration and fo...

  • Some limitations of rheostatic control

    Publication Year: 1911, Page(s):1605 - 1619
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1694 KB)

    We may consider the limits of rheostatic control under three classes, functional, where the limitations are inherent to the type of control; resistance material, where the limitations are due to physical characteristics of the rheostat material, and switching devices where the limitations apply to the method of adjusting resistance.

  • Electric line oscillations

    Publication Year: 1911, Page(s):1621 - 1668

    In the summer of 1910 some tests were performed on the lines of the Great Western Power Company, which are operated at 100,000 volts, to obtain information on oscillations and rises of potential, due to switching operations. In these experiments the oscillograph was extensively used and this paper deals with some of the most important and representative records. View full abstract»

  • The use of power-limiting reactances with large turbo-alternators

    Publication Year: 1911, Page(s):1669 - 1720
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (6843 KB)

    In large electric power systems the maintenance of a very high degree of reliability, that is, continuity and uniformity of service, must be the constant aim and is one of the principal problems of the engineer. While the problems during the earlier years of central station work often appeared very difficult, the advent of the large capacity, high-speed turbo-generators coupled to systems containi...
