  • The dielectric circuit

    Publication Year: 1937, Page(s):1434 - 1440
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3718 KB)

    The dielectric circuit is a baffling enigma to many undergraduate students of electrical engineering; indeed, to many engineers whose work is not intimately concerned with it. This outline of some of the elementary notions regarding electrostatics and the dielectric circuit is presented here because of its possible interest and value to students and others wishing to review the subject with the ai...

    Improvements in the transmitter and receiver, instruments basic to the telephone art, continually have led to a higher grade of service and further economies. Research work has made possible predetermination of performance by calculation; the effect of studies of speech sounds, hearing, materials, and testing methods on the development of instruments giving high quality for conversation is shown b...

    THE BOSTON Elevated Railway serves a population of about 1,531,000 people, distributed over an area of 111.56 square miles and segregated in 14 municipalities, including both towns and cities. Within its territory the railway supplies practically all of the public transportation, except taxicabs. The backbone of its system is formed by its rapid-transit division, with elevated lines, subways and s... View full abstract»

    THE INVESTIGATION described in this paper was undertaken to determine the magnitude and characteristics of the abnormal voltage transients accompanying the operation of load ratio control contactors on power transformers. As test results definitely established the fact that currents may be abruptly ruptured at other than normal current zero, accompanied by very severe over-voltages, the main purpo...

  • The enlarging concept of engineering

    Publication Year: 1937, Page(s): 1475
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (382 KB)

    IN proportion as the concept of “laws of nature” grows larger to include individual human behavior and group action, the engineer is called upon to apply his time-tested methods to broader problems of state and country. The usual definition of engineering, as the science and art of applying laws of nature to human needs, still holds; only the laws of nature cannot be limited any long... View full abstract»

  • Network-analyzer solution of multiple unbalances

    Publication Year: 1937, Page(s):1476 - 1482
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1734 KB)

    SOME EXAMPLES of multiple unbalances on a 3-phase network are: 1. Two or more unsymmetrical short circuits at different points of a network. Faults involving more than one circuit are not unusual on multicircuit lines, and simultaneous faults sometimes occur even at geographically separated points, especially on systems grounded through high impedance. System stability or operation of relays durin... View full abstract»

    This paper describes the operation of a modern trolley coach system. This system was installed one year ago with a single line and a few coaches. Now there are 7 lines in operation, the total route lengths exceeding 45 miles and requiring 40 coaches, each of which has a seating capacity of forty persons. The paper is generally divided into 2 parts, the first dealing with descriptions of the system... View full abstract»

  • Stray-load losses of D-C machines

    Publication Year: 1937, Page(s):1487 - 1491
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1395 KB)

    This article describes a method of measuring stray-load losses which is readily adaptable to the test departments of the manufacturers. Usually no additional test apparatus will be required beyond that already available. The same arrangement used for a pump-back heat-run test is used with only slight modification. Experimental data are given showing the effect of speed, load, and field strength up... View full abstract»

  • Oil oxidation in impregnated paper

    Publication Year: 1937, Page(s):1492 - 1501

    MUCH HAS BEEN written recently on the influence of oil oxidation on the properties and stability of impregnated paper insulation. It is thought by many to be a principal cause of deterioration in high voltage cables. Oxygen is highly soluble in cable oils; if present in appreciable quantity and at moderate temperature elevation, the oils oxidize rapidly with consequent loss of insulating value. Ho...
