    Two 115-kV submarine cable crossings were recently completed by Puget Sound Power and Light Company under deep channels of Puget Sound. One was 14 100 feet long with a maximum depth of 720 feet. The other was 6400 feet long with a maximum depth of 388 feet. Laying directly from the factory reels proved satisfactory for the shorter crossing, but trouble was experienced with the cables of the deeper... View full abstract»

    115-kV lengths of oil-filled submarine cable were manufactured. Tests on samples from the center of 12 800-foot lengths were equal to tests on short lengths. Oil flow tests conducted in the factory and field tests of oil pressure are compared with calculated data. A flexible splice for emergency use was designed and tested. View full abstract»

    Viscosity and dielectric loss of insulating liquids have been recognized as exponential functions of temperature; however, sufficient coordinated proof was previously unavailable. This study correlates and analyzes the theoretical predictions with available experimental results and, also, clarifies the importance of the concept of the ion content of insulating liquids as an indication of electrica...

    The determination of the short-time transient temperature rises of self-contained oil-filled cable systems, which is a necessary part of the calculation of their oil demands and pressures, requires finding the roots of an equation involving Bessel functions. Families of curves are presented from which the roots may be obtained by simple calculations for any given cable system, together with other ... View full abstract»

    A study was carried out on the corona discharge rate and energy loss occurring within artificial cavities. An air gap with metallic electrodes was utilized to simulate the ionization sources within a cable. The corona discharge rates, obtained with varying gap spacings under different vapor pressures, showed marked deviations from the idealized behavior. thhe calculated tangent ¿ values, in terms...

  • Investigation of Cement-Fly-Ash Concrete Mixtures for Underground Conduit Construction

    Publication Year: 1965, Page(s):780 - 788

    Concrete mixes that are especially applicable to underground conduit-line construction are evaluated. Concretes in-herently release free lime which, in sufficient concentration, is corrosive to lead cable sheaths. Varying amounts of fly ash were used in trial concrete mixes, and the resulting reduction in free lime release was measured. A calcium lignosulfonate type of dispersing agent was added t...

    Lightning and other surges have been a major problem on aerial cable systems connected to open-wire lines. In 1957, an experimental cable line with variation in shield construction was installed in an area with high lightning incidence. This paper reports the service and test record of the line. In seven years, the line has suffered 19 test failures and one service failure. These failures occurred... View full abstract»

    Circulation of oil in pipe-type feeders has been employed, to a limited extent, to accomplish either of the following two objectives: 1) temperature-averaging to minimize the effect of unknown hot-spot zones, or 2) an increase in circuit capacity above the self-cooled level. This paper reports, in two sections, on both types of application, which were initiated in 1952 and carried out subsequently... View full abstract»

    In 1962, the Association of Edison Illuminating Companies and the Insulator Power Cable Engineers Association sanctioned 10°C higher conductor temperatures for use in rating calculations by utilities having thorough knowledge of the thermal characteristics of the soil in which a particular cable is to be installed. A 2-stage sampling scheme is described for obtaining such knowledge with a minimum... View full abstract»

    Surface discharge phenomena associated with unshielded nonmetallic sheathed power cables, particularly in the 3000- to 15 000-volt classifications, have been the subject of considerable research. These cables have induced surface voltages which are responsible for surface leakage currents and associated surface discharges, which combine to form a phenomenon generally referenced as surface-tracking...

    The reactive power flow in utility systems produces losses which utility engineers try to keep at a minimum with the installation of capacitor banks. Load flow studies usually furnish a good indication of where they will render maximum benefit. In many instances, they can be installed on primary feeders. A study is made of the optimum location, size, and timing of capacitor banks on feeders with u... View full abstract»

    A method is presented for calculating the radio noise level of a transmission line where the radio noise generation is produced by corona on station apparatus. Propagation of the radio noise energy is described by a set of noninteracting transmission modes. Field factors which transfer line voltages to electric-field values at the ground level are presented as modal quantities. Two specific exampl... View full abstract»

    This paper presents a practical design for unbalanced insulation of transmission lines and describes lightning performances on 70- and 140-kV lines. The basic practice of unbalanced insulation is to install one circuit at a higher insulation level than another circuit in order to eliminate double-circuit flashover. The effectiveness of this design was demonstrated by laboratory tests and field exp... View full abstract»
