  • Engineering education as a preparation for any life work

    Publication Year: 1935, Page(s):358 - 361

    In our present day engineering civilization, is there a logical basis for the thesis that an engineering education is a good preparation for any life work? President Johnson says there is, and in this article gives strong supporting reasons for his contention. He concludes that a broad basic engineering education “which opens the mind and shows it how nature itself does its work, and teache... View full abstract»

  • Circuit breakers for Boulder Dam line

    Publication Year: 1935, Page(s):366 - 372
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4785 KB)

    Because of its length, 270 miles, the 275 kv transmission line from Boulder Dam to Los Angeles, Calif., requires extremely high speed switching for stability. To meet the requirements, a high voltage impulse circuit breaker, extending the oil blast theory to cover a multibreak construction with double cross-blast ports, has been built. It provides over-all switching times consistently less than 3 ... View full abstract»

  • Direct measurement of surge currents

    Publication Year: 1935, Page(s):373 - 378
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1630 KB)

    A new instrument, called the surge crest ammeter, based upon the principle of magnetic retentivity has made available a direct and simple method of measuring surge currents. A study of the behavior of 2 magnetic links under the influence of oscillatory surge currents has made this instrument useful in measuring the per cent oscillation as well as crest values of surge currents. Specimen measuremen... View full abstract»

  • Armature leakage reactance of synchronous machines

    Publication Year: 1935, Page(s):378 - 381

    An extension of the Potier method of testing for armature leakage reactance of synchronous machines is presented in this paper, wherein it is shown that the easily tested for Potier reactance varies considerably and therefore has a limited field of usefulness. It is further shown that if the Potier reactance is measured at high values of field current, the armature leakage reactance is closely app... View full abstract»

  • Cable sheath corrosion causes and mitigation

    Publication Year: 1935, Page(s):382 - 387
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2365 KB)

    The causes and mitigation of telephone cable sheath corrosion are dealt with in this paper, which describes particularly a method of applying a counter potential to the cable sheath for the mitigation of corrosion from localized currents. This method, although not new, has had but limited application. It may find extensive future use for controlling corrosion on intercity toll cables, and in local... View full abstract»

    In its introductory part, this paper explains why the transient speed changes of d-c motors under suddenly applied loads may affect the quality of the product rolled on a continuous rolling mill. In a later section, the paper analyzes the behavior of such motors driving a tandem tube mill, and points out the difference between the transient and the steady-state speed-load characteristics; the form...

    Definitions of power, power factor, and related quantities in an a-c circuit have been prepared in an effort to provide definitions which will be generally acceptable. If such general acceptance is obtained, they will be published as a part of the revised report on “Definitions of Electrical Terms” which is being prepared by the Sectional Committee on Electrical Definitions.

  • Instantaneous overcurrent relays for distance relaying

    Publication Year: 1935, Page(s):404 - 407
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (917 KB)

    Instantaneous isolation of faults on transmission and distribution lines is ever a problem of the relay engineer. The use of instantaneous overcurrent relays as applied to the system of the Oklahoma Gas and Electric Company is discussed in this paper. Relays of this type were applied in conjunction with already installed overcurrent time delay relays, giving a form of distance relay protection. Op... View full abstract»

  • Calculation of power flow and bus voltages

    Publication Year: 1935, Page(s):408 - 416
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1767 KB)

    The method for calculation of power flow and bus voltages in a-c networks described in this paper is based upon Kirchhoff's laws, and is novel mainly in that the power losses are lumped at the network terminals in determining power flow. The effect of circuit shunt capacitance is included. Problems in which the ratio of resistance to reactance in all branches is constant, and also problems in whic... View full abstract»

  • A criterion of quality of cable insulation

    Radial uniformity of oil impregnated paper cable insulation, that is, uniformity in a radial direction from conductor to sheath, is a characteristic of well manufactured cable that is fully as important or more so than longitudinal uniformity. Radial power factor curves for several brands of new cable included in this paper show marked irregularities which are attributed to poorly controlled manuf... View full abstract»

    A number of examples in which an increased intensity of illumination in industrial establishments resulted in an actual increase in production are cited in this paper. Other results also attributed to adequate lighting are that better work can be done, accidents are reduced, and waste space may be made available for production. View full abstract»

    The value of probability theory in the field of engineering is forcefully brought out in this paper, which explains the fundamentals of the theory, not by the use of mathematics, but by the solution of sample problems of types frequently encountered. View full abstract»

  • Lubrication increases life of meter bearings

    Publication Year: 1935, Page(s):428 - 431

    Recent research reported in this paper shows that lubrication of pivot bearings of electric watthour meters is essential for maximum bearing life. The performance of these bearings represents the most important mechanical factor in sustained meter accuracy. The comparatively high rate of wear in a new bearing is found to decrease rapidly with use, finally becoming extremely small. With a well lubr... View full abstract»
