    “Cosmic rays” is the name applied to the ultimate cause of that part of the ionization of the air that cannot be ascribed to any known agencies. In spite of this prosaic definition, however, seldom if ever has there been a subject of research in physics in which intrinsic importance and romantic associations so happily are combined. In view of the fundamental importance of cosmic ray... View full abstract»

    Distribution transformers in several locations on a New England system have been operating for several months with the primary lightning arrester ground interconnected with the transformer secondary neutral. Experience over the past few months definitely indicates the advantages of this connection in reducing troubles due to lightning, without increasing the hazard to the customers' wiring. Increa...

    IN SWITZERLAND, the country of the “white coal” as electricity is called there, another important electrification has been accomplished by the construction of a large seasonal storage plant, the Oberhasli hydroelectric development above Meiringen in the Bernese Oberland. Construction work on the first step of this project was completed recently and the Handeck generating station was ... View full abstract»

    AN ADDRESS “The Era of Public Enterprise” was delivered by Walter Rautenstrauch, professor of industrial engineering, Columbia University, New York, N. Y., at a meeting of the Advertising Club of New York, held March 1, 1933, in that city. Following Professor Rautenstrauch's address, which extolled the benefits expected from increased public enterprise, an address was given by Dr. Vi... View full abstract»

  • I — Public enterprise

    Publication Year: 1933 , Page(s): 234 - 236

    THE MANY suggestions for the solution of our economic difficulties put forward during the past 3 years of the depression are so varied in their proposals and in the principles underlying them that it seems almost hopeless for us to arrive at any concerted action to get us out of our difficulties. This seems to be due to 2 causes: First, an entire lack of common understanding of basic economic prin... View full abstract»

    THE REAL difficulty with the pattern of public enterprise, the idea of having a government of any sort, whether of engineers, economists, or Tammany politicians, run our industries and businesses in an orderly fashion lies in this simple fact: We, as a people, and as individuals, are not made in the way we would have to be to fit into the pattern. Perhaps we can be made to fit some day, but that i... View full abstract»

  • Sheath grounds affect traveling waves in cables

    Publication Year: 1933 , Page(s): 238 - 239

    Traveling waves may appear in power cables connected to high voltage transmission lines. The differences in voltage that will appear between the conductor and sheath of a cable at various points depend upon the nature and location of the cable sheath grounds. A few of the results of a considerable number of tests made to determine their effect are presented in this article, and some conclusions re... View full abstract»

  • Conductor vibration from wind and sleet

    Publication Year: 1933 , Page(s): 240 - 242
    Request Permissions | Click to expandAbstract | PDF file iconPDF (450 KB)  

    Conductors on electric power transmission lines have been observed to vibrate with amplitudes as great as 20 ft during sleet storms with the temperature just below freezing, and with a heavy wind blowing transversly across the line. An explanation of this phenomenon is given. View full abstract»

    Some important requirements for modern steel tower transmission lines are presented in the following outline prepared by Group II of the A.I.E.E. subcommittee on steel transmission towers and conductors. This material is intended as a general guide to designers and is not a specification. Clearances, mechanical reliability, strength against lightning, and prevention of vibration, are considered.

  • Non-linear circuits applied to relays

    Publication Year: 1933 , Page(s): 244 - 246
    Request Permissions | Click to expandAbstract | PDF file iconPDF (452 KB)  

    In this article are described applications of simple series and parallel non-linear electrical circuits to a-c voltage and current relays; such relays are characterized by great sensitivity. The special properties of the resonant-current relay make it especially adaptable for use as an undercurrent or undervoltage relay. View full abstract»

  • Some new ideas in circuit breaker design

    Publication Year: 1933 , Page(s): 247 - 248

    IN THE LIGHT of the present trends that are influencing the design, application, and operation of circuit breakers in electric power systems it seems reasonable to expect that the satisfactory circuit breaker of the future must have the ability to interrupt, in a few cycles and with minimum arcing, a circuit carrying a large load, and do this effectively without the use of oil. In the course of el... View full abstract»

    Among the many interesting and valuable applications of that versatile device, the 3-electrode hot-cathode gas-filled thermionic tube, is the inverter. Of the several different types of circuits developed, the “parallel” type gives promise of becoming of some importance, and already has been used commercially for supplying power to a-c radio sets from d-c systems.

    “Reactive power” is discussed in this article from the point of view of the practical operating engineer. The direction of flow in a transmission line of this reactive power with respect to the “active” power is shown to determine whether the current lags or leads the voltage. It is urged that only one kind of reactive power (lagging) be recognized, and that its directi... View full abstract»

  • III — Reactive and fictitious power

    Publication Year: 1933 , Page(s): 268 - 270

    The single-phase and polyphase definitions of reactive power are considered in this article. It is shown that the single-phase definition is unsatisfactory with complex waves. The polyphase definition is better, but requires independent recognition of distortion and mesh distribution. A distinction is made between fictitious power and reactive power. View full abstract»
