  • The frequencies of natural power oscillations in interconnected generating and distribution systems

    Publication Year: 1943, Page(s):791 - 803

    THE distribution of power in the steady state of interconnected electric networks with large numbers of generators and of consumers of power is well known for a given system. The flow of energy in detail depends on the distribution of the loads, on the admission of power to the prime movers, and on the data for all the connecting lines. With every change of the power distribution in any branch of ... View full abstract»

  • The Sorocabana railway electrification

    Publication Year: 1943, Page(s):804 - 818
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3543 KB)

    The Sorocabana Railway electrification is noteworthy in that the railroad is a meter-gauge line run largely on wood fuel. The lack of suitable national coal or oil sources and the increasing difficulty of obtaining wood fuel led the railway to electrify its line between São Paulo and Santo Antonio. Rolling stock is outstanding in that the locomotives will be the most powerful 3,000-volt nar... View full abstract»

  • The effect of corona on coupling factors between ground wires and phase conductors

    Publication Year: 1943, Page(s):818 - 826
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2505 KB)

    Measurements of coupling factors between ground wires and phase conductors, as a function of ground-wire voltage, have been made for a sufficient number of cases to determine them for any of the standard transmission-line configurations. It was found that the effect of corona can be expressed in terms of an effective corona ground-wire radius to be used in the conventional coupling-factor equation... View full abstract»

  • Pole-face loss in solid-rotor turbine generators

    Publication Year: 1943, Page(s):827 - 834
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (759 KB)

    ONE of the primary problems which confront the designer of electrical machinery is the predetermination of losses. This is peculiarly true for the designer of high-speed turbine-driven generators; the losses must be kept low, not only to increase the efficiency but also to keep the size of the apparatus to a minimum.

  • Application of carrier to power lines

    DURING the 20 years or so that have elapsed since power-line carrier was first introduced on a commercial basis, enormous advances have been made in the communication arts. In the somewhat specialized branch of power-line carrier, advances in technique and apparatus design have not been as highly publicized as those in some other branches of the art; nevertheless, they have kept pace with the fiel...

  • Safe ratings for overhead line conductors

    Publication Year: 1943, Page(s):845 - 853
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (938 KB)

    Many factors must be considered in establishing safe ratings for overhead copper line conductors. Most important is the low-temperature annealing and loss of strength of the hard-drawn copper itself. Others are the effect of atmospheric conditions and line location relative to structures and topographical features tending to obstruct the wind. The actual construction details of the line, such as g... View full abstract»

    The present war emergency requires that the maximum use be made of existing equipment and systems and that a minimum of critical material be used for new equipment. This publication and other guides and reports of this series have been prepared for the information of users during the war emergency. Upon termination of the war emergency, they will be reconsidered by the Standards committee and the ... View full abstract»

  • Theory of rectifier — D-C motor drive

    Publication Year: 1943, Page(s):863 - 869
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1407 KB)

    THE use of rectifiers for furnishing power to d-c motors is becoming more common, particularly for variable-voltage drives. The theory applying to drives such as those incorporating the Ward Leonard system is quite inadequate for use with a rectifier-d-c motor drive. This paper is an introduction to the theory involved when operating a d-c shunt-wound motor from a rectifier. It is hoped that furth... View full abstract»

  • Electronic control of D-C motors

    Publication Year: 1943, Page(s):870 - 877

    IN recent years the need for an improved adjustable-voltage d-c motor drive operated from an a-c supply has been continually increasing. Although the conventional drive of that type using a motor-generator set, and sometimes referred to as the Ward-Leonard system, adapts a d-c motor to an a-c line and provides adjustable armature voltage for the motor, it does not solve all of the problems involve...

    IN a previous paper1 the basic equations for the stator and rotor-winding currents of the capacitor motor were established in terms of certain coefficients which were functions of the fundamental constants of the machine. Application of these relations to establish the current loci was made to typical design data taken from earlier papers by Morrill,2 and Puchstein and Lloyd,... View full abstract»

    THE purpose of this paper at the present time is to make available for the aircraft industry knowledge and information on the newest types of transformers specially developed to obtain extreme small size and the lightest possible weight. It is felt that the aircraft engineers should be given every opportunity to take advantage of the latest developments without the delay of extensive research. Eve... View full abstract»

    LOW-frequency carrier has been applied extensively to distribution circuits for remote control of street lights, window lights, off-peak water heaters, and similar services. Since carrier makes available a control system whose operating flexibility can be duplicated only by the use of a number of separate wire or pilot circuits, it permits saving large amounts of copper and other critical war mate...
