    Coupling to high-voltage transmission lines for purposes of carrier-current communication was first. universally made by means of coupling wires. This type of coupling usually required high-power transmitting equipment, but when coupling capacitors were substituted it was possible to reduce the carrier input to the line without affecting the received signal strength. The paper gives an approximate... View full abstract»

  • The Relation Between Frequency and Spark-Over Voltage in a Sphere-Gap Voltmeter

    The standard instrument for measuring crest values of high alternating voltages at 60 cycles is the sphere-gap voltmeter, which measures a voltage by the distance which it will flash between spheres. In much of the high-voltage research, however, very high frequencies are used. For measuring the voltages used in these high-frequency tests, the sphere-gap voltmeter is used, the assumption being mad... View full abstract»

    A qualitative analysis of the nature of the space charge created about a conductor in corona, particularly with respect to relative magnitudes and polarities, rather than actual quantitative measurement, is described here. This work was the principal work on corona during the past year in the Ryan High-Voltage Laboratory. In tests with the arrangements of a wire and a plane, and of a wire and a cy...

    This paper, after referring to the results of a previous study of the electric oscillations on the three-phase aerial line obtained by Dr. Bekku, describes the additional work done by the writer concerning the electric oscillations in the double-circuit, three-phase transmission line, and shows that there are three kinds of traveling waves. The nature of these waves, and some of the important resu... View full abstract»

    The paper deals with records which have been obtained during short circuits upon the Southern California Edison's 220-kv. system. The main features of the system are outlined, and such operating data as are necessary to afford an understanding of the various conditions which have to be met are included. The general scheme of relays is described, and the causes of flashovers and their times of occu... View full abstract»

    This paper discusses the characteristics of equipment which have been found most suitable for use on 220-kv. systems or on extensive lower voltage systems. Consideration is given to general system design, governors of prime movers, generators, excitation systems, transformers, high-voltage oil circuit breakers, transmission line, and the equipment of substations. The result of four years' operatio... View full abstract»

  • Static Stability Limits and the Intermediate Condenser Station

    The principal features of this paper may be summarized as follows: For static stability calculations, power systems may be represented by a network with constant impedance and admittance branches with as many terminals as the number of synchronous machines requiring individual consideration. This method is justified because, as developed in the paper, loads may be represented by the equivalent con... View full abstract»

    The paper reviews the general characteristics of large synchronous condensers, with particular reference to the possibilities of greater standardization in condenser specifications. Particular emphasis is placed on the question of the ratio of lagging to leading kv-a. capacity, and it is concluded that about 50 per cent lagging capacity is normal, while any important increase in this ratio require...

    Part I is an introduction, showing the need for reliable records of power disturbances in transmission lines, and showing that the incandescent-lamp oscillograph is the only practicable recorder of such chance disturbances. Part II describes the Power Osiso which is a very compact and highly efficient oscillograph, having an instantaneous wattmeter, a permanent-magnet galvanometer, and a relay arr...
