    Cited by:  Papers (96)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2428 KB)

    Recent advances in the theory of synchronous machines have introduced a large number of new constants. The method of symmetrical components requires sequence reactances, and an accurate theory of transients requires transient and subtransient reactances and time constants. Most of the published discussion on the constants has been concerned with the application, rather than the calculation of valu... View full abstract»

    This paper is essentially a mathematical study of transient voltages in transformer and other distributed windings, and is primarily concerned with showing the effects of wave shape, circuit constants and neutral impedances on the voltage distributions, and how these distributions may be controlled or changed. In the appendix there is derived the general differential equation for a circuit consist... View full abstract»

    The complete mathematical solution of applying suddenly a d-c. voltage to an electromagnetic circuit composed of an electric coil with a partly laminated and partly solid iron core containing an air-gap is presented in this paper. Starting from Maxwell's field equations for the eddy currents and the magnetic field in the iron core, the solution of the time conditions is reached with the aid of Hea... View full abstract»

    The services rendered by an interconnection between two or more electric power systems may be classified as: 1. Emergency service??by which assistance is given by one system to the other in event of breakdown of equipment or other abnormal conditions. 2. Load diversity??arising from the non-coincidence of the times of peak loads in the interconnected systems. S. Firm power??transactions involving ... View full abstract»

    The possibilities of interconnection can only be realized when the system is effectively developed and operated. The interconnected system functions as a unit but the companies owning the different parts have diverse interests which must be sufficiently coordinated both in development and operation to make the benefits of the interconnection available to all the participants. There is question as ... View full abstract»

    The paper outlines the communication requirements of electric utilities and suggests effective methods for meeting those requirements. Operating, customer service, and administrative activities are considered separately. However, the advantages of a unified communication system for all activities are outlined. The relative merits of cable, open wire, power line carrier and radio are reviewed. The ... View full abstract»

    In 1923 an amendment to the International Convention of 1875 relating to weights and measures gave the International Committee of Weights and Measures authority to deal with the electrical units. This committee was thereby confronted with two major problems concerning the magnitudes of the units and the best procedure for their legalization and maintenance. It set up an Advisory Committee of exper... View full abstract»
