    The necessity of recognizing load factor in rate schedules is emphasized. To obtain load factor necessitates the measurement of maximum demand; a new maximum demand meter is described which depends upon heat and heat storage. The theory of such meters is discussed. A new method of measureing power factor and volt-amperes is disclosed and a method of recognizing power factor in the rate for electri... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2012 KB)

    The paper gives results and analyses of tests to determine losses in hysteresis loops wherein the magnetism is carried through cycles in which limiting values of flux are different in amount or the mean values of flux differ from zero. Such variations of magnetism occur in inductor generators, in teeth of induction machines and in materials magnetized from rectifier circuits, etc. The author finds... View full abstract»

  • The effect of displaced magnetic pulsations on the hysteresis loss of sheet steel

    Publication Year: 1915, Page(s):2321 - 2342
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2907 KB)

    Most modern revolving electrical apparatus has teeth on the rotor or stator, or both, which are subjected to constantly varying reluctance. This variation of reluctance causes high frequency changes of flux superimposed on the working flux. The result is a series of displaced hysteresis loops. This investigation was undertaken to determine the magnitude and, if possible, some of the laws governing... View full abstract»

  • Recent results obtained from the preservative treatment of telephone poles

    Publication Year: 1915, Page(s):2343 - 2387
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5897 KB)

    The results of an experience with treated poles over a period of 18 years have been analyzed. Data are given for poles treated by pressure, open tank, and brush methods. The relation of these methods of treatment to the conditions which have determined the choice of pole timbers in the United States is outlined. The experience with brush treatments has reached a more advanced stage than that with ... View full abstract»

    The repulsion start induction motor for single-phase current has come into considerable prominence during the last 10 or 15 years as is fully attested by the large number of motors of this type now in operation, and by the increasing demand and production. While there is considerable literature available on the subject of repulsion motors both compensated and noncompensated and on induction motors... View full abstract»

    It is frequently a question how far it is advisable to go in the application of automatic control, and the writer discusses a number of typical examples from the standpoint of a field engineer of a manufacturing company. Any successful scheme of control must be such as can be produced by the manufacturer and used by the purchaser with profit to both. A review of many of the well-established system...

  • Decomposing magnetic fields into their higher harmonics

    Publication Year: 1915, Page(s):2437 - 2454
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1315 KB)

    When it is necessary to decompose a magnetic field into its higher harmonics the same methods used for analyzing current and voltage waves may be employed. In many cases, however, the usual long mathematical operations can be avoided by representing the field shapes as geometrical figures, such as triangles rectangles, trapezoids, etc., all of which waves may be considered as composed of a number ...
