    It is generally agreed that a sine wave of electromotive force at generator terminals and on transmission lines is best. A sine wave is now specified as standard by the Standardization Rules of the Institute, but the present methods for prescribing allowable limits and for determining how near an actual wave is to a true sine wave are very unsatisfactory. The Standards Committee, through a sub-com... View full abstract»

  • The high-voltage potentiometer

    Publication Year: 1916, Page(s):1187 - 1192
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1676 KB)

    The author describes a high voltage potentiometer which may be made at reasonable expense consisting of a water resistance potential distributor and a sparking probe potential difference detector. The water resistance consists of a column of water moving slowly through an ample length of garden hose, and tapping in points through which to connect the probe are provided by breaking the hose at regu...

  • Underground distribution systems

    Publication Year: 1916, Page(s):1193 - 1208

    The object of this paper is to show the importance of properly designing an underground distribution system for the district it serves and the particular service it is to supply. Simply placing the wires underground does not constitute an efficient system. Underground distribution is the ultimate solution of the distribution problem that confronts every Electric Light and Power company operating i... View full abstract»

  • Some features of domestic electric cooking and heating

    Publication Year: 1916, Page(s):1209 - 1219
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1199 KB)

    Although electric cooking and heating has always been considered possible, it has only recently become popular; hence the engineer is found unprepared with information on the characteristics of the load. From tests made on a number of domestic cooking and heating installations, it would appear that electric cooking has a better load factor than a lighting load and that this load factor improves as...

  • Testing for defective insulators on high tension transmission lines

    Publication Year: 1916, Page(s):1221 - 1235
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3171 KB)

    This paper discusses the importance and necessity of field tests on high-tension insulators and three methods of making such tests, viz.; with the oscillator, the megger, and the telephone receiver. The latter is described in detail, and some data given on its development and use on a 60,000-volt line in western Washington, covering a period of 2.5 years. Laboratory checks on 13 of the defective i... View full abstract»

  • Insulator failures under transient voltages

    Publication Year: 1916, Page(s):1237 - 1244
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4775 KB)

    The operation of a high-voltage transmission line involves changes in energy distribution that are very conducive to high-frequency disturbances and transients of very steep front. These are often superposed on the normal frequency voltage of the line in such a way as to impose great stresses on the insulators. The mechanism of failure of an insulator is of great importance to those designing and ... View full abstract»

  • An artificial transmission line with adjustable line constants

    Publication Year: 1916, Page(s):1245 - 1257
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (15654 KB)

    A description is given of an artificial transmission line which can be readily adjusted to represent 200 miles (321.86 km.) of commercial transmission lines of any spacing up to a maximum of 120 in. (3 m.) and any size wire up to 4/0 copper. It can also be made to correspond to aerial or cable telephone lines and to power cables. The use of this type of line in laboratory courses on transmission l... View full abstract»

  • Steel conductors for transmission lines

    Publication Year: 1916, Page(s):1258 - 1272
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1570 KB)

    The electrical tests of some steel conductors of moderately large size have been published, and they indicate that there is an opening for the profitable use of steel cables on the branch lines of power systems of all voltages, in the same way that small steel conductors have already been used on branch lines at low voltages. Mechanical weakness or corona loss prohibits the use of small copper or ... View full abstract»

  • A distribution system for domestic power service from commercial and engineering standpoints

    Publication Year: 1916, Page(s):1273 - 1280

    The adoption of electric heating and cooking has begun to reach' such large proportions that the average distribution system is unable to take care of the increased load. As the domestic power load in all probability will increase until every house is electrically equipped, this paper has endeavored to lay out a distribution sysem to take care of this class of business and to estimate the revenue ...

  • Temperature rise of insulated lead-covered cables

    Publication Year: 1916, Page(s):1281 - 1306
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1992 KB)

    After a brief historical note the factors that determine the rating of a cable are considered. The thermal conductivity of a cable is expressed in terms of the volume thermal conductivity of the insulation, the surface thermal conductivity of the lead sheath, and the dimensions of the cable. The values of the thermal conductivities as given by various observers including the author are compared. A... View full abstract»

  • Discussion on high-voltage D-C. railway practise (Renshaw), New York, April 14, 1916 (see proceedings for April, 1916)

    Frank J. Sprague: Mr. Renshaw's interesting paper offers a gratifying opportunity for reflection to one who has been identified with the development of electric railway advancement since its commercial inception, and who may fairly claim to have played a not inconsequential part in that development. It offers a luminous example of what is known in law as a plea of “confession and avoidance,... View full abstract»
