    Marked economies may be secured by standardizing industrial products to eliminate all unnecessary sizes and ratings. Based upon a system of “preferred numbers” selection of desirable sizes may be made with reasonable accuracy through the use of algebra and geometry supplemented by judgment and common sense.

  • Steam vs. electricity for driving power station auxiliaries

    Publication Year: 1932, Page(s): 20
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (206 KB)

    During the past few years important changes effected in power station and system design have reduced operating expenses materially. At present, however, station designers are giving more attention to the reducing of investment costs. This reduction of plant investment quite naturally affects the plant auxiliaries as well as other station equipment. Many large stations built recently have practical... View full abstract»

  • Steam vs. electricity for driving power station auxiliaries: I — Importance of reliable auxiliaries

    Publication Year: 1932, Page(s):20 - 21
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (571 KB)

    A WELL DESERVED reputation for continuity of service is enjoyed by the electric service industry as a whole. The public has become accustomed to receiving continuous service; furthermore, the large investments of the power station companies and of their industrial customers demand an uninterrupted supply of energy. One of the most important factors vitally affecting continuity of power service is ... View full abstract»

  • II — Steam driven plant auxiliaries

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1569 KB)

    RELIABILITY may be set down as the most outstanding requirement of electric power station auxiliaries since, among other things, an uninterrupted supply of power depends upon the ability of the essential auxiliaries to function continuously. Thus any arrangements made for guaranteeing the operation of these auxiliaries should be appropriate to the degree of service reliability expected from the st... View full abstract»

    A REVIEW of the history of auxiliaries for steam power stations shows a gradual change from complete steam drive to the other extreme of complete electric drive, except for a few reserve steam driven auxiliaries such as boiler feed pumps and service pumps. During an intermediate period, dual steam and electric drive was used quite extensively for some of the essential auxiliaries, but the number o... View full abstract»

    INSULATING MATERIALS of the type at present being used in electrical design are difficult to interpret from the standpoint of fundamental characteristics and behavior, not only because of their underlying complexities, but also to a large degree because of their lack of purity. As yet satisfactory methods for gaging the chemical purity of such materials have not been developed despite the fact tha... View full abstract»

    PROCEEDINGS of the second session of the insulation conference held recently at Harvard University (see footnote) are reviewed here. Like the preceding session under the guidance of the subcommittee on chemistry, this general session was featured by a distinct scientific atmosphere. Several papers were presented dealing with the electrical properties of important types of simple and complex dielec... View full abstract»

    IN THE session of the Harvard University insulation conference (see footnote) held under the auspices of the subcommittee on physics, a series of five papers bearing on present physical theories of dielectric behavior was presented. In the first of these, W. F. G. Swann drew a series of analogies amongst the accepted mathematical developments of the theories of steady currents in conducting media,... View full abstract»

    ARC WELDED steel framing for dwelling houses is representative of some of the recent experiments in modern building construction. Many advantages are claimed for the welded type of construction, among them being: rapidity and noiselessness of construction, flexibility of design, rigidity and solidity, low rate of depreciation, and a lower insurance rate resulting from the fireproof construction wh...

  • New high speed distance relay with impedance reactance characteristic

    Publication Year: 1932, Page(s): 39
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (328 KB)

    THE TWO general types of distance relays for isolation of faulty sections of transmission line are impedance relays, operating upon the impedance of the line between the relay and the fault, and reactance relays, operating upon reactance alone. Each of these types has certain advantages as well as certain disadvantages; it is the purpose of this new relay to combine the principal advantages of bot... View full abstract»

  • The theory of oil blast circuit breakers

    Publication Year: 1932, Page(s): 39
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (328 KB)

    DIRECT experimental proof of the oil blast theory of arc interruption has been assembled. A circuit breaker has been constructed having oil driven between its electrodes at a measurable velocity, and tests show that a correlation exists between the rate of recovery voltage rise and oil velocity. This correlation corresponds to an oil dielectric strength of 55 kv. per 1/10 in. of oil. To determine ... View full abstract»

    DEVELOPMENTS in theory, calculation, and test results of circuit interruption by means of the oil blast, have placed new tools in the hands of designers, enabling them to construct apparatus of greater efficiency and consistency of performance than heretofore possible. Various applications of these new methods have been made to circuit breakers of all classes and voltages. Circuit breakers equippe... View full abstract»

    THE EXTINCTION of an a-c. arc by the deion grid method has been very successfully applied during the past two years to the design of an extensive line of arc rupturing devices for oil circuit breakers of all voltage classes. Refinements have been made in the theory of operation of deion grids and in the construction of several types. Field operation and special tests have given much information re... View full abstract»

    IN CIRCUIT breakers employing arcs submerged in liquids such as oil, carbon tetrachloride, or water, the surrounding liquid surface serves both to restrict the are space and to furnish a gas blast by rapid decomposition under the influence of the high temperature arc. The fiber tube of the common expulsion fuse acts in a similar manner. In the liquid circuit breakers, various devices are available... View full abstract»
