    This paper is presented for the purpose of describing a new method of compensation, by the use of which the ratio and phase-angle errors of current transformers are materially reduced. There are several similar methods now in use, but these methods possess some undesirable features which are not present in the one described in this paper. By the use of this new method, in which a portion of the se... View full abstract»

    In addition to surveying the field of application of “telemetering” and relating it to “supervisory control,” the paper presents several innovations in the types of “telemeters” available. Operating requirements and channels available for the transmission of readings are discussed, and an installation of the varying frequency type of telemeter on the Monta... View full abstract»

  • Abridgment of anomalous conduction as a cause of dielectric absorption

    Publication Year: 1929, Page(s):186 - 189

    THE two most important properties of an insulating material are high dielectric strength and long life. The close correlation with changes in dielectric loss clearly indicates that an understanding and control of the loss will point the way to longer life. The close relationship between dielectric absorption and dielectric loss has been shown experimentally,37 and in fact the familiar d... View full abstract»

    The paper presents an accurate theory of the split-phase motor, both as regards starting and running performance. The general equations for an unbalanced two-phase motor are first derived, and the results are then applied to the special case of the capacitor motor. Evidence of the validity of the theory is given in the form of curves, comparing test results with calculations. The principal factors... View full abstract»

    STARTING with the basic assumption of no saturation or hysteresis, and with distribution of armature phase m. m. f. effectively sinusoidal so far as regards phenomena dependent upon rotor position, general formulas are developed for current, voltage, power, and torque under steady and transient load conditions. Special detailed formulas are also developed which permit the determination of current ... View full abstract»

    The objections to unnecessary noises in electrical apparatus are becoming so insistent that the manufacturers are making every effort to reduce them. In order to attack the problem intelligently it is first necessary to determine the amplitude and frequency of the components of the complex sounds. The first requirement then is a simple portable sound analyzer. Descriptions are given of the resonan... View full abstract»

    The purpose of this investigation is to give a mathematical theory of the cyclograms of corona obtained by a cathode ray oscillograph. In the case investigated a long wire of small diameter is connected to one terminal of an a-c. source; the other terminal of the source is connected to a concentric cylinder of considerable diameter, or to a metal plate at some distance from the wire. A cathode ray... View full abstract»

    Besides the copper loss and the dielectric loss, the losses occurring in single-conductor armored cables, whose sheath and armor are bonded and grounded at more than one point, are the circulating-current losses in the sheath and in the armor, and the additional iron losses in an armor of magnetic material. The circulating-current losses are due to the currents induced in the sheath and armor circ... View full abstract»

    That simplified practise will be applied on an increasing scale by industry and business in 1929 is forecast by the increasing number of requests to the division of simplified practise for its cooperation; by the increasing number of inquiries reaching it regarding the application of simplified practise to wholesaling and retailing; and by the increased recognition and support accorded completed s...

    The experience of the Alabama Power Company with carrier-current telephony over power lines and supervisory control is outlined in the paper. A sketch is included of the early development of these systems, and this is followed by descriptions of the systems later installed throughout the Company's territory. In an Appendix extracts are given from the general specifications for the equipment employ... View full abstract»

  • Abridgment of flux linkages and electromagnetic induction in closed circuits

    Publication Year: 1929, Page(s):219 - 223
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1021 KB)

    It is shown that the flux linkages of a circuit may be changed in two very different ways — either the flux may be varied causing a voltage to be induced according to Faraday's Law of Electromagnetic Induction, or the turns may be varied by a substitution of circuit without inducing a voltage. In the Appendix, it is mathematically shown that the flux may be changed either by transformer or ... View full abstract»

    In 1923 the “mile of standard cable” was replaced in the Bell System by a new unit for expressing telephone transmission efficiencies and levels. At that time, the generic term “transmission unit” was taken to designate this new unit, since it was considered desirable to defer the adoption of a more distinctive name until this unit had been given further consideration b...

    This paper describes an experimental attempt to separate the stray load losses of large ac turbine generators, making use of the fact that the loss in any of the various parts is proportional to the initial rate of temperature rise in that part. Comparisons are made between tests conducted with rotor structure removed and short-circuit tests. View full abstract»

    The A.I.E.E. Standards have provided high-potential test values as a means of establishing a standard basis of design and construction of insulation. Many purchasers test equipment after installation before placing it in service to be sure that the connections and equipment are in a safe condition for service. It is recommended that a standard test voltage be established that may be used under the... View full abstract»

    Many manufacturers of polyphase squirrelcage induction motors in the integral horsepower sizes have now added to their other products, a modified form of squirrelcage motor in which the starting current is reduced below that of the standard squirrelcage motor. The reduction in starting current is sufficient to warrant the power companies throughout this country to permit the starting of these moto... View full abstract»
