    THE GENERAL ELECTRIC Extra-High-Voltage Project (called “Project ehv” for short) involves the design, construction, and operation of a complete a-c transmission system which will carry power at voltages from 460 to 750 kv. This system will be a prototype of future extra-high-voltage systems. Data obtained from the system will be integrated with analytical studies, model investigation... View full abstract»

    Today's compelling need is that of absorbing the impact of science and technology for the common good. This is a responsibility of all of us, because each advance affects the whole spectrum of our society and its institutions. The essential requirement is an enlightened citizenry, prepared to submerge individual interests in the group interest and to orient to new values when and as necessary. View full abstract»

  • Dielectric strength and voltage life of polyethylene

    Publication Year: 1958, Page(s): 681
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (251 KB)

    AMONG the most promising types of material for insulating high-voltage cables are those in the polyethylene family. Since its introduction around 1940, polyethylene has been used successfully for submarine telegraph and telephone cable, for high-frequency coaxial communication cable, and for multiconductor control cables. It has also been used, in increasing quantities, for high-voltage cable. Its... View full abstract»

  • Frequency response of a nonlinear closed-loop system

    Publication Year: 1958, Page(s): 689
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (237 KB)

    THIS ARTICLE PRESENTS two general concepts which are very valuable in analyzing nonlinear servomechanisms. A graphical procedure is introduced by which the frequency response of a nonlinear closed-loop system can be determined from the describing function. The theory is even valid for the general describing function which is both amplitude and frequency dependent (Fig. 1). View full abstract»

  • Mechanism for nontracking organic insulations

    Publication Year: 1958, Page(s): 699
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (259 KB)

    MOST ORGANIC INSULATIONS are not suitable for high voltage applications in contaminated atmospheres. Under surface arcing conditions, the organic constituents of the insulation decompose to form carbonaceous paths and the apparatus will fail by progressive creepage tracking. This article describes a proposed internal oxidation mechanism to eliminate formation of carbonized tracks upon exposure to ... View full abstract»

    Many utilities, faced with the problems of expansion, have initiated long-range studies to evaluate the possibilities of using extrahigh transmission voltages, such as 345 kv. In this article, 345-kv systems are compared with the more commonly used 138-kv systems on the basis of right-of-way requirements, reliability of operation, and cost. View full abstract»

  • Current-carrying capacity of acsr

    Publication Year: 1958, Page(s): 719
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (244 KB)

    THE CONTINUOUS current-carrying capacity of transmission lines is dependent upon the allowable temperature of operation of the conductors. A great deal of test work has been performed in the investigation of this problem on ACSR (aluminum cable, steel reinforced). However, two factors—the effect of the sun and of the altitude of the line—have not received consideration heretofore. View full abstract»
