    This paper describes what is believed to be the nation's first completely transistorized pole-mounted 10-watt VHF land mobile radio repeater station powered by a combination rechargeable battery and thermoelectric generator unit. Over 2 years of field experience has been accumulated since this Station was installed December 7, 1962. The Unique power supply, which has been an unqualified success, c... View full abstract»

  • Power Line Carrier Coupling Investigations on a 500-kV Line

    Some previously accepted concepts of power line carrier coupling do not apply on power lines with very few transpositions. For such lines, the attenuation and impedance of the carrier circuit may be strongly dependent on which phase conductor is selected for coupling. This phenomenon has been investigated in a series of tests on a long 500-kV line with one transposition near the middle. The result... View full abstract»

    This paper will investigate the technique of modal analysis applied to propagation of signals on overhead transmission lines. The propagation problem is first analyzed in phase quantities at a constant frequency and then with modal transformations in the original differential equations. From the model analysis, properties of modal transformations are deduced. This analysis shows that when earth co... View full abstract»

    This paper will discuss the magnitude of earth correction terms calculated from available references. It is concluded that Carson's earth correction terms are predominant, and curves detailing the magnitude of these are presented. Examples showing the magnitude of Carson's earth correction terms for a given line at 60 c/s, 50 kc/s, and 1 Mc/s are shown. A modal analysis, using the technique develo... View full abstract»

    A method of coupling with directional characteristics can have two significant advantages in power line carrier work: it will remove the need for wavetraps, and it will expand the communication capacity of the power lines. The disadvantage is that system inefficiencies may require more transmitter power. A simple theory for directional couplers is provided, and the theoretical results are compared...

    A transistorized relay recently installed to predict generation instability resulting from major system disturbances is described. The relay can be used to initiate corrective measures, such as generation tripping or dynamic braking, to maintain stability. Several advantages over the present methods of initiating corrective action are obtained by use of this relay. View full abstract»

  • Calculation of the Ratio and Phase-Angle Errors of Phase-Shifting Autotransformers

    Publication Year: 1965, Page(s):224 - 228

    The determination of the ratio and phase-angle errors of a phase-shifting transformer is quite difficult without special test equipment of adequate sensitivity and precision. Although formulas for the calculation of these errors in two winding potential transformers are available, they cannot easily be applied to the interconnected autotransformers used for phase shifting. This paper demonstrates ... View full abstract»

    The two aspects of engineering education are the teaching of science and the teaching of design. By ``design'' is meant the procedure of selecting and combining distinct elements to create complete systems which will perform useful functions. In this paper, the author describes the application of this concept of design teaching at The Technical University of Denmark, after a procedure which includ... View full abstract»

    Many problems of insulation coordination are concerned with the protection of an air gap by means of another air gap: protection of the external insulation of a bushing by means of a rod gap, protection of line-to-tower insulation by means of the ground hardware of an insulator string, protection of the open gap of a switch by means of the line-to-ground insulation of the stack, etc. When dealing ...

    This paper develops a theoretical method which leads to an efficient practical one and provides a mathematical basis for establishing EHV switching-surge ratings. Detailed analyses of the major factors involved in EHV testing are presented. Application of statistical and probability mathematics to the test results indicates the necessity of a rigorous evaluation of the test data and the need for d... View full abstract»
