  • Surface leakage as a factor in insulator design

    Publication Year: 1920, Page(s):803 - 806
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (845 KB)

    The various factors influencing surface resistance and methods of increasing it, are discussed. It is shown that the most economical way of decreasing the leakage is the addition of properly proportioned corrugations on the under side of the flange or skirt. Typical computations are given, showing the approximate increase to be expected when corrugations are added. View full abstract»

    THE Hog Island Shipyard, near Philadelphia, Pennsylvania, constructed as a war measure, and which is known all over the world as one of the largest shipyards in existence, is operated throughout by electrical power purchased from the Philadelphia Electric Company and transmitted over a double-circuit, 66,000-volt stranded copper No. 00 tranmission line. There is also another single-circuit line op... View full abstract»

    Data are presented giving the iron losses for five-mil, 4 per cent silicon steel sheet for a range of frequencies from 5000 to 50,000 cycles per second. An approximate separation of hysteresis and eddy current losses is made showing the result of skin effect on these losses. A method of test is described which if desired could be used over a much wider range of frequencies than those indicated. Th... View full abstract»

    POWER for the electrical operation of the Chicago, Milwaukee & St. Paul Railway, between Harlowton, Mont. and Avery, Ida., is delivered to the transmission system of the Railway in the form of 100,000-volt, three-phase, 60-cycle current. The power is supplied under two separate contracts, one for the Rocky Mountain Division, extending from Harlowton to Deer Lodge, and the other for the Miss... View full abstract»

  • The electric dynamometer test of the Pierce arrow engine

    Publication Year: 1920, Page(s):819 - 821
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3394 KB)

    THE electric dynamometer is now generally recognized as the standard equipment for testing automobile engines. Dynamometers are used not only to measure the power of the engine in the final test but also are employed as tools in the production of the engine. Engines when first assembled are “run in” on block test dynamometers until the bearings, etc., are worked in. In this process t... View full abstract»

    IN some investigations by the authors during the Great War occasion arose to solve the following problems: Problem A. Given the dimensions and permeability of a straight cylindrical iron core, how many ampere-turns, uniformly distributed over the length of the core, are required to produce a given magnetizing force (magnetic field intensity) at a point on the axis of the core at a distance from it...

  • The current-carrying capacity of lead-covered cables

    Publication Year: 1920, Page(s):831 - 839
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1928 KB)

    This article gives data whereby the carrying capacity of lead-covered cables can be calculated on the basis of thermal limitations. Carrying capacity as limited by voltage drop or economical considerations is not discussed. The article shows how further data can be applied as these are determined. An appendix contains some numerical examples illustrating the use of the data. It also contains a cha... View full abstract»

    The proposed electrification of the industries of the island of Ceylon, and a partial transformation of the transportation systems from steam to electricity, offer a large opportunity in hydroelectric development today. The proposed scheme, developed by the Public Works Department, has been under consideration for a number of years past. Definite action was delayed because of the war, but it is ex...

    A new form of weir and a simple, straight-line formula have been devised by Clemens Herschel, Past-President, Am. Soc. C. E., for gaging the flow of water in open channels. This weir and the accompanying formula are results of experiments made by Mr. Herschel with the support of Engineering Foundation, at the laboratory of Massachusetts Institute of Technology. A report of the experiments was pres... View full abstract»
