    The demand for strictly professional engineering service will diminish in volume but will rise sharply in its qualitative standards, while the demand for quasi-professional services will increase markedly. This is one of the opinions voiced by Doctor Wickenden in a recent address, full text of which is presented herewith. In order to prepare men to furnish these services most ef... View full abstract»

  • An improved electrothermic instrument

    Publication Year: 1935, Page(s):474 - 481
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1851 KB)

    An improved electrothermic instrument for measuring watts, amperes, or volt-amperes, actuated by the thermal expansion of a liquid in a closed system which includes a Bourdon tube, is described in this paper. The new instrument is not subject to the errors inherent in the bimetallic strip type of electrothermic instrument, it has a linear input-deflection characteristic, and its time period may be...

    The rapid increase in the use of electric power equipment in steel plants in the United States during the last 3 decades is outlined briefly in this paper, and the principal types of apparatus now in use are discussed. Power generation and distribution equipment is considered briefly and the types of electric motors used in different kinds of main mill drives are outlined. Synchronous motors and d...

  • A stroboscopic power angle recorder

    Publication Year: 1935, Page(s):485 - 488
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2153 KB)

    An automatic stroboscopic power angle recorder developed to study directly the transient performance of synchronous machines during load disturbances is described in this paper. A portion of the machine under observation is illuminated by stroboscopic light, and its oscillations are recorded directly by a moving-film camera. The operation of the device is made automatic by connecting a suitable re... View full abstract»

  • D-C braking of induction motors

    Publication Year: 1935, Page(s):488 - 493
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1310 KB)

    The rapid deceleration of induction motors from relatively high speeds to standstill by the application of constant potential to the terminals is considered in this paper. Applications in which d-c braking of induction motors is desirable are mentioned, and the fundamental principles involved in this method of braking are considered. The characteristics of the speed-torque curve are derived from t... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (6500 KB)

    Marking a new milestone in the history of the transmission of electric power, the 275 kv system that will transmit power from Boulder Dam to Los Angeles, Calif., embodies many novel engineering features. These features are discussed in this paper. The paper includes not only a description of the line and the terminal equipment and facilities, but also a discussion of the effects of the characteris...

  • Time-temperature tests to determine machine losses

    Publication Year: 1935, Page(s):512 - 515
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1495 KB)

    Time-temperature tests as a means of measuring losses in electrical machines are described in this paper, and some of the results which have been secured with such tests are described. The method consists principally in determining by test the initial slope of the time-temperature curve of some part of the machine, immediately after a steady load is thrown off. In this paper, application to the an... View full abstract»

  • Storage battery charging

    Publication Year: 1935, Page(s):516 - 525

    The fundamental reactions in accordance with the generally accepted “double-sulphate” theory of storage battery charging are comparatively simple. Additional reactions and phenomena, such as gas evolution, acid concentration, heating, and local action are factors which affect charging conditions. Data showing the effects of these factors are given in this paper. The ampere-hour law r... View full abstract»

  • An analysis of the induction motor

    Publication Year: 1935, Page(s):526 - 529
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (743 KB)

    For problems involving induction motors other than the usual balanced winding type operating under steady-state conditions, a general method of analysis is necessary. In this paper, a general analysis is presented, and in particular, its use in short-circuit problems is described. The comparison between tests and calculated results indicates that the method does properly describe induction motor p... View full abstract»

  • The determination of circuit recovery rates

    Publication Year: 1935, Page(s):530 - 539
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2001 KB)

    Actual interruption of an a-c circuit depends upon the ability of the circuit breaker to prevent the re-establishment of the arc after the current goes through zero and the arc goes out. In some circuits full voltage appears across the contacts as quickly as 40 to 80 microseconds following the current zero. This recovery rate in volts per microsecond depends upon the triple product of: the current... View full abstract»

  • Capacitive excitation for induction generators

    Publication Year: 1935, Page(s):540 - 545
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1421 KB)

    Up to the present, applications of induction generators have been limited, mainly because they must be paralleled with an existing synchronous system to determine their frequency and voltage and to obtain their necessary excitation. The tests described in this paper show that an induction machine may be operated as an independent or isolated generator at a predetermined voltage and frequency, with... View full abstract»

  • Effects of saturation on machine reactances

    Publication Year: 1935, Page(s):545 - 550
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1330 KB)

    The effects of magnetic saturation on the various types of reactances used in calculations on synchronous machines are considered in this paper. Saturation factors for the important constants used in transient and unbalanced load calculations are presented in curve form. These data are taken from short-circuit tests on a large number of machines. The saturation factor for transient reactance under... View full abstract»

    Complex hyperbolic function charts covering the range ordinarily found in problems dealing with long electric power transmission lines are presented herewith. By restricting the charts to this range, it has been possible to draw them to a large scale so that good accuracy can be obtained from these comparatively small charts. View full abstract»
