  • Zone-Packaged Ground Distance Relay: I - Principles of Operation

    Page(s): 1021 - 1044
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (3276 KB)  

    A novel basis has been developed for designing distance relays that will detect ground (earth) faults in a preset zone of transmission lines. The fundamental basis is described, and the relay performance is analyzed mathematically over a wide range of power-system conditions to show its constancy of reach and proper sense of direction. A relay designed on this basis can be zone-packaged and is inherently directional. View full abstract»

  • Bibliography of relay literature, 1961-1964

    Page(s): 1044 - 1053
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (2570 KB)  

    This bibliography is a continuation of similar bibliographies of relay literature which have been published previously in various volumes of AIEE Transactions. The papers listed include references to the subjects of service restoration, testing, and methods of calculation, as well as to the field of relaying. Only the more readily available foreign publications are included. Many of the articles are available in abstract form in Science Abstracts - Section B, the Engineering Index, and other digesting or indexing periodicals, as well as in the original magazine listed. The listing of the titles is subdivided into 13 sections depending upon the general substance of each article. The entries in each section are numbered consecutively and listed in alphabetical order. The name of the first author determines the alphabetical position. Each title is listed in only one section even though some of the papers referred to may cover material in various sections. A list of the periodicals which have been cited and their place of publication is given following the bibliography. View full abstract»

  • A New Multiplex Technique for Communication Systems

    Page(s): 1054 - 1059
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1266 KB)  

    A new technique for multiplex communication is described, in which orthogonal pulse waveforms are transmitted as simultaneous subcarriers. Information signals are carried in the form of independent amplitude modulations of each subcarrier, and are extracted by means of waveform correlation. Known as ORTHOMUX (orthogonal multiplexing), the new technique offers the advantages of: 1) high spectrum efficiency, 2) maximum rejection of crosstalk and noise, 3) information response down to zero frequency, 4) mixed information rates, 5) simple, compact equipment, and 6) modular flexibility.

  • Communication Circuits on 500-kV Lines

    Page(s): 1059 - 1064

    The characteristics of 500-kV transmission lines from a communication viewpoint are discussed based on tests and observations of the Tennessee Valley Authority's first 500-kV line to be placed in service. Dead-line carrier frequency tests included attenuation on the insulated shield wires and phase-coupled power-line carrier arrangements. Modal component attenuation, relative velocity of propagation, and other characteristics of natural mode behavior are covered. Experiences to date on operation of power-line carrier terminals and audio equipment are given, along with a brief resume of RI measurements. View full abstract»

  • A Guide for the Protection of Wire Line Communications Facilities Serving Electric Power Stations

    Page(s): 1065 - 1083
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (11352 KB)  

    Some of the wire communications circuits entering electric power stations are used for control and relaying purposes and often are called upon to perform certain operations during periods of power system faults. This constitutes a major problem in the design of the communications system, since power faults usually result in the introduction of extraneous currents and voltages into the commuuications circuit just at the time when the latter is most urgently required to perform its function.

  • Switching Surges: II - Selection of Typical Waves for Insulation Coordination

    Page(s): 1091 - 1097
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (3845 KB)  

    A number of wave shapes, which typify the whole spectrum of switching surges in electric utility power systems, are rationally selected. These surges were chosen to facilitate expansion of the basic knowledge of switching surges in regard to both the characteristics of such surges and the ability of insulation to withstand them. They should prove useful in the solution of insulation coordination problems. View full abstract»

    The author of the above-named work, which appeared on pp. 727-741 of the July, 1966, issue of these Transactions, has requested that several corrections be made: In the lower right-hand part of Fig. 1, Gri should be Gr1. The equations in the caption of Fig. 2 are corrected herein, and the caption of Fig. 3 should read, "The 2-area system with elastic tie line"; and Fig. 4, "A 2-area and an n-area stiff tie-line system."
