    Resonant transmission lines may be used as circuit elements in the ultra-short wave range as a means of obtaining high impedance with low loss. The lines may be of either concentric tubes or 2 wires, and are sufficiently small that they may be placed within the apparatus. These circuits can be made highly selective, and when used to control oscillator frequency will give stability comparable to that of a crystal. The mathematical relations governing their operation and several applications are discussed in this paper. View full abstract»

    Edison's observation of the discharge of negative electricity from the carbon filament of an incandescent lamp to an auxiliary electrode in the bulb, commonly known as the ``Edison effect,'' remained unexplained until the beginning of the 20th century. Since that time, an entire new industry??radio??has grown up as a result of continued research in the emission of electrons from hot cathodes. This article, seventh of a series prepared under the sponsorship of the A.I.E.E. committee on education, reviews some of the more important observations and conclusions obtained from investigations in this field.

    Although much is yet unknown about the many Factors concerned in insulator arcover, humidity tests presented here lead to a theory of arcover. The geometrical design of the insulator is shown to be a minor factor at power frequencies, but of importance for withstanding impulse voltages. View full abstract»

  • A Glow Discharge Anemometer

    Page(s): 1068 - 1073

    A glow discharge at atmospheric pressure is responsive to air velocity, and may be used as an anemometer. The properties of such a glow are discussed in this paper, and data relating to glow current, voltage, glow length, and air velocity are presented. It is also shown that the glow discharge responds to rapid fluctuations in air velocity and is therefore a practical device for investigating turbulence. A comparison of such an anemometer with the previously used hot wire method is given. View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1932 KB)  

    The behavior of distance relays during system oscillations is analyzed in this paper, and curves are presented for determining whether the oscillations are likely to cause relay operation. Different types of distance relays are considered and general methods of analyzing system conditions are discussed. View full abstract»

  • Reignition of an Arc at Low Pressures

    An investigation of factors influencing the reignition potential of an alternating current arc at low pressure is reported in this paper. The investigation was undertaken to determine if such data could throw more light on the transition from a glow discharge to an arc. The results are consistent with a theory proposed previously by one of the authors. View full abstract»

  • The Expulsion Oil Circuit Breaker

    In the expulsion type of oil circuit breaker the arc occurring on circuit interruption is ``expelled'' from the contact chamber by a high velocity gas blast. Breakers of this type have demonstrated their capability of consistently interrupting short circuits on a typical large electric power system within 1 or 2 cycles of arc. In this paper the theory of this type of breaker is presented and its performance is analyzed. View full abstract»

    Tests have been conducted on an experimental transmission line equipped with a counterpoise for reducing the tower Footing surge impedance so as to give added protection against lightning. The results of these tests are presented herewith, and should prove valuable to engineers engaged in the design and operation of transmission lines. The desirability of further tests made under a variety of conditions is indicated. View full abstract»

  • Field Tests on Conductor Vibration

    Field tests on transmission conductor vibration as affected by dampers and suspension clamps have been made in an attempt to find a solution to the important problem of stopping such vibration in an economical manner. This paper presents some data in regard to number and spacing of the ``Stockbridge'' type damper. The question of whether vibration is transmitted through or stopped by various types of suspension clamps also is discussed, and actual records of frequencies on both sides of suspension clamps shown.
