  • Modern developments in precision timekeepers

    Publication Year: 1932, Page(s):542 - 549

    Clocks of the gravity or pendulum type have for many years been used as precision timekeepers; but through recent refinements they have been made more accurate and reliable. Another development of the last decade is the use of the elasticity of quartz crystal oscillators as the restoring force in precision timekeepers; this has been made possible by the vacuum tube and associated electrical circui...

    Police organizations throughout the country rapidly are adopting the teletypewriter, the latest development in record communication. By this means alarms are typed at one point and simultaneously recorded in printed form at a large number of widely scattered stations. The engineering of facilities required for a modern police system involves the solution of many special problems. View full abstract»

    Analysis of various circuit problems may be facilitated by the substitution of equivalent circuits which reduce the complexity and permit the replacing of magnetic coupling with simple impedance links so that the calculating board may be used for solution. In this article, general methods of solving the transformer, network, and zero phase sequence problems are presented along with useful diagrams... View full abstract»

    The proximity effect, usually considered as undesirable and wasteful, may be used to concentrate heating currents in predetermined strips of conducting bodies. Both the current density and shape of the strip may be so controlled as to make this method valuable in a number of heating processes. View full abstract»

    Field tests substantiate the results of theoretical and laboratory investigations of conductor vibration on electric power transmission lines treated in an article appearing in the July issue of ELECTRICAL ENGINEERING. Among other important findings it is shown that adequate practical protection against damage from conductor vibration can be provided by the proper use of armor rods or dampers. View full abstract»

    Because of the relatively high voltage used and the necessity of mounting the apparatus in a limited space, many new problems of control design were encountered in the 3,000-volt d-c. suburban electrification of the Lackawanna Railroad. This article describes the construction and operation of some of the more important of the control apparatus developed, and the tests made to assure its suitabilit... View full abstract»

    By building large capacity mercury arc rectifiers from a group of several small sections, the better efficiency, reliability, economy, and flexibility inherent in the smaller rectifiers can be retained in the larger units. Experiments on a 3,000-kw. rectifier composed of 4 750-kw. units, shows an efficiency one per cent higher than for the conventional single unit type. View full abstract»

    An improved voltage limiting gap for protecting electric power station apparatus has been developed, the breakdown characteristics of which may be varied over a wide range so as to conform to the characteristics of the station insulation. For the best protection, a lightning arrester in parallel with the gap is recommended. View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (354 KB)

    THE SYSTEM LOAD of the British Columbia Power Corporation, Ltd., is concerned principally with lighting, domestic power, and small industrial power. With one exception no heavy contract load is carried. Owing to the seasonal and climatic influences the load factors are inherently low, the annual load factor ranging for several years between 45 and 48 per cent, with little immediate prospect of imp...

  • Segregation of hydroelectric power costs

    Publication Year: 1932, Page(s): 583
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (354 KB)

    THE PRODUCTION COST of electric power is made up of the power or demand cost per kilowatt and the energy cost per kilowatt-hour. The relative amount of each of these items which make up the total cost of power at the power station determines the cost at any load factor. The above segregation of the annual production cost of power is essential in determining the power rates and the economic design ... View full abstract»

    THE ELECTRIFICATION of the Reading suburban service in the vicinity of Philadelphia was first placed in operation July 26, 1931. The lines now under electrical operation include 65 route miles and 157 track miles, which will be increased by January 1, 1933, to 87 route miles and 203 track miles. These lines consist of 6 branches and cover all the suburban territory north of Philadelphia, between t... View full abstract»

    ELECTRIFICATION of the Great Northern Railway's main line between Skykomish and Wenatchee, 73 route miles, was carried out in conjunction with the building of a new tunnel 7.79 miles long, and the relocation of approximately 17 route miles of troublesome track and other minor improvements, aggregating an expenditure of approximately $25,500,000. Although all of these improvements were placed in op... View full abstract»

    AN ANALYSIS of the theory of the 3-wire d-c. generator using a 2-phase static balancer is presented in this paper with the particular object of explaining the very large unsymmetrical magnetizing current peaks which occur in the balancer windings. These peaks are evidence of unsymmetrical flux variation attaining high values of flux density; and as their value may be equal to, or greater than, the... View full abstract»

    CONTENTS of previous publications on metering of symmetrical components have been confined to the components of current and voltage in 3-phase 3-wire systems. This paper discusses the method of metering the positive and negative sequence power and energy in 3-phase 3-wire systems, and positive, negative, and zero sequence power and energy in 3-phase 4-wire systems. Networks are described which mak... View full abstract»

    NONE of the methods previously available to improve transformers is capable of producing an important requirement of the power industry; namely, the high accuracy, high voltage, low ratio, bushing type current transformer operated at a high secondary burden. However, in analogy with the molecular theories of magnetization, a method of shaping magnetization curves has been advanced for securing con... View full abstract»

    DESIGNS and factory procedure for factory assemblies of medium voltage substations which may be applied to either network or radial distribution systems are described in this paper. These substations may be divided roughly into 2 principal classes, those for serving large individual power consumers and those for general distribution to a community of varied customers. In the latter class may be in... View full abstract»

    DURING the summer and fall of 1931, measurements at the Harris J. Ryan Laboratory, Stanford University, Calif., extended the range of corona loss data for conductor sizes beyond those investigated during 1930. In these latter tests the 3 conductor specimens studied were a 1.125-in. hollow copper cable, a 1.49-in. hollow copper cable, and a 2.0-in. hollow aluminum cable. The losses were measured on...
