  • The best control of public utilities

    Publication Year: 1915, Page(s):1 - 23

    The author states as an axiom that “the best control of a public utility is that which develops an eagerness and ability on the part of the company to furnish the service, and an equal eagerness and ability on the part of the consumer to purchase the service.” Five elements requisite for the development of this eagerness and ability on the part of the company and the consumers are st...

  • Theoretical investigation of electric transmission systems under short circuit conditions

    Publication Year: 1915, Page(s):25 - 69
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3351 KB)

    The following features of a transmission system under short-circuit conditions are discussed: 1. Mechanical forces between the phases of three-conductor, three-phase cables when carrying short-circuit current; also the forces between busbars are investigated. 2. The heating of the conductors of the cable from the instant of short circuit to a time 0.8 seconds later is traced analytically, during t... View full abstract»

  • Discussion on “voltage testing of cables” (Middleton and Dawes), Detroit, Mich., June 25, 1914. (see proceedings for June, 1914)

    W. A. Del Mar: The factor of safety of an insulated wire or cable, being the ratio of the breakdown voltage to the normal operating voltage, cannot be determined experimentally without testing the insulation to destruction. It can, therefore, never be definitely known in practise, although susceptible of approximate predetermination in the absence of faults, by calculation based upon tests. If, ho...

  • Discussion on “methods of keeping down peaks on power purchased on a peak basis” (Tynes), Detroit, Mich., June 23, 1914. (see proceedings for June, 1914)

    Rudolph Tschentscher: Power contracts, as you all know, are usually made on a peak basis, and the question of the reduction of these peaks is a most important one. I believe it is desirable to emphasize the point Mr. Tynes has mentioned, namely, that the reduction of peaks is of material benefit to the power generating company. Paul M. Lincoln: This point that Mr. Tynes has raised is an exceedingl... View full abstract»

    R. Tschentscher: The division entitled “Gas Engines” comprises internal combustion prime movers using natural gas, producer gas, or blast furnace and coke oven gas. The relative measure in which each enters into the problem is not given. In 1907, blast furnace gas engine installations began in the iron and steel industry. It was my lot at that time to place in service and operate the... View full abstract»

  • Discussion on “the sphere gap as a means of measuring high voltage” (Peek), “the electric strength of air — V, the influence of frequency” (Whitehead and Gorton), and “sphere gap discharge voltages at high frequencies” (Clark and Ryan), Detroit, Mich., June 24, 1914.

    L. W. Chubb: These three papers presented under the auspices of the Electrophysics Committee are very interesting, and they add a gread deal to our knowledge of high-voltage phenomena. The paper on the sphere gap by Mr. Peek adds some valuable experimental data on the effect of barometric pressure on the gap voltages. The effect of temperature, however, as expressed in the empirical formula, seems... View full abstract»

    P. M. Lincoln: We may represent a three-phase system as in this diagram, in which the figure ABC may be assumed to rotate around its center O. The instantaneous voltages will then be proportional to the lengths of the projections upon a line, as XX. For instance, at the instant represented in the figure the instantaneous voltage of leg AO is zero, that of phase CB is a maximum, and those of phases... View full abstract»

    J. Harisberger: There has been considerable discussion as to the necessity of synchronous condensers on this system. I would like to know what actual practise in the operation of the system has brought out; could the system be operated satisfactorily without the use of synchronous condensers? Mr. Woodbury's paper states that under conditions of short circuit the waterwheel governors shut off water... View full abstract»

    Paul Lebenbaum: This paper looms up as an oasis of facts in a desert of glittering generalities, and records a distinct step forward and upward in heavy railway electrification. It is unique in that it sets forth, not only facts, but actual figures on operating results, for a road that made the change from steam to electricity solely in order to obtain increased capacity and greater economy in ope...
