This paper discusses effect of shielding lines on reduction of electric field produced by overhead lines. Charge simulation method is used. Influences of height, space and number of shielding lines on electric field are calculated. Space between shielding lines has reverse roles on influencing area and maximal electric field. Number and space of shielding lines should be carefully selected to shielding a certain area. Analytical method is also used to express induced electric field by shielding lines. Result of comparison with charge simulation method shows that it is suitable for area outside of three phase lines.

Abstract Electrostatic induction charge which generated by the coupling effect of hybrid electric field of AC/DC cross line and metal object under the transmission line can cause different levels of electric shock injury to human. In order to find out the distribution law of the hybrid electric field and reduce the effect of electrostatic induction, this paper set up shielding lines which paralleled to the AC and DC lines respectively on the outside of the side conductors and along the diagonal of parallelogram at crossing point, then measured the electric field distribution in shielding areas of 750kV AC and 500kV DC lines and the induced voltages of shielding lines in different states, analyzed the effect of shielding line on power frequency electric field and DC composite electric field. The results showed that shielding lines have a reducing effect on the hybrid electric field of the cross lines, the average power frequency field strength is reduced by 12.6%, the DC composite field and power frequency electric field at the crossing position was far less than the limits specified in the respective standards. Both induced voltage of bare lines and shielding lines wrapped with adhesive tape increase with the raise of erection height. Under the same conditions, the average induction voltage of bare conductor is 9.3% higher than that of shielding lines wrapped with adhesive tape. There is no obvious difference between parallel and vertical erection methods of the same number of shielding lines in the degree of reduction of induced voltage.

Wood Poles are extensively used in North America as supports for electric distribution lines. On average, wood poles have a service life of 40 years with a replacement cost of approximately $2000. Since the distribution network is of relatively recent construction, maintenance and replacement costs have been relatively small compared to the total number of poles in service.
The goal of this thesis is to use the FORM/SORM algorithm to evaluate the reliability of a single pole and the results obtained when applied to a sample of 887 wood poles inspected in the field. The procedure was also applied to a sample of poles designed according to the current codes in order to calibrate the evaluation procedure. The results indicate that the proposed procedure will improve the current maintenance and replacement strategy by guarantying a more uniform level of reliability throughout the network and by decreasing by up to 33% the number of wood pole replacements.

Thesis (MScEng)--University of Stellenbosch, 2001,
ENGLISH ABSTRACT: A frequency domain Power Line Carrier (PLC) simulation program, with the ability to simulate signal attenuation including the coupling equipment, was developed. This simulation program was put to the test against the independent program of Professor L.M. Wedepohl and against practical field measurements. The predictions of the two programs were in precise agreement for a wide range of input parameters. Results from the field tests and predictions also showed close agreement. Further investigations, applying the simulation program, explained how ground conductors and soil resistivity influences PLC signal propagation. An experiment, which was developed to monitor PLC signal attenuation, was installed on the PLC system between Koeberg power station and Acacia substation, both near Cape Town. Data logged continuously over 28 days, indicated measurable and deterministic PLC signal attenuation variations with typical time constants of a few hours. Simulations of the PLC system indicated that the signal amplitude variations were influenced by changes in the height above the ground plane of the phase conductor. This significant finding creates the possibility to obtain real time knowledge of the sag of an Over Head Transmission Line (OHTL) by exploiting an operational PLC system. The knowledge about real time sag can be used in economical dynamic ampacity control systems. The practical and financial benefits to the electricity supply and distribution industry can be significant.
AFRIKAANSE OPSOMMING: 'n Frekwensie gebied "Power Line Carrier" (PLC) simulasie program wat die sein verswakking en die koppeling verliese kan naboots, is ontwikkel. Die program is getoets teen die onafhanklike program van Professor L.M. Wedepohl asook praktiese metings in die veld. Die vooruitskatings van beide programme is presies die selfde vir 'n wye reeks van parameters. Metings en nabootsings het ook noue ooreenstemming getoon. Verdere ondersoek, m. b. v. die program, is gedoen ten einde te verduidelik hoe grond-geleiers en grond weerstand die PLC sein se voortplanting beïnvloed. 'n Eksperiment om die PLC sein se verswakking mee te monitor is ontwerp. Die eksperiment was geïnstalleer in die PLC stelsel tussen Koeberg kernkragstasie en Acacia substasie, naby Kaapstad. Die eksperiment was vir 28 dae geaktiveer en die data wat die eksperiment opgelewer het toon meetbare PLC sein verswakking met tyd konstantes van 'n paar uur. Verdere nabootsings het gewys dat die veranderende verswakking in die PLC seinsterkte toegeskryf kan word aan die wisseling in hoogte van die fase geleiers bo die grondvlak. Hierdie bevinding is van besondere belang aangesien dit die moontlikheid oopmaak om die gemiddelde sak van kraglyne in reële tyd en onder bedryfs toestande te kan meet. Die informasie van die reële sak van kraglyne kan gebruik word in effektiewe stroomdrae-vermoë beheer stelsels. Die praktiese en finansiële voordele wat krag voorsieners en verspreiders hieruit kan put kan aansienlik wees.

Several methods for calculating the electrical phase and modal parameters of overhead transmission lines are described in this thesis; then, a graphical method for evaluating communication frequency response of delta transmission lines -based on the guidelines given by W. H. Senn [12,13,14]- is developed. The graphical method, combined with the parameters calculation methods, obviates the need of large mainframe computers for the analysis of power line carrier (PLC) systems. A new technique for assessing coupling alternatives, based on Senn's method, is developed. The technique is applied to generate coupling recommendations; it is found that many of the current recommendations given elsewhere [21] are not reliable. Finally, future work to be done in this field is proposed.

Abstract Flexible printed circuits (FPCs) are widely used in electronic devices such as movable part line or wearable sensor. Inkjet printing is attracting attention because it can draw electric lines of any shape without a photo mask. The mechanical characteristics such as flexibility or durability of electric lines have been evaluated by bending and tensile tests. Moreover, the reliability characteristics of metal particle ink lines under electric current loading have been recently evaluated. However, the electronic line has not been evaluated under both the mechanical stress due to bending deformation and the electrical stress due to electric current. According to scaling down of electric devices, the current density and Joule heat in interconnect line increase and electromigration (EM) damage becomes a serious problem. EM is a transportation phenomenon of metallic atoms caused by electron wind under high-density electric current. Reducing EM damage is extremely important to enhance device reliability. In this study, high-density current loading tests of flexible electronic line were conducted under bending deformation of the substrate in order to investigate the effect of mechanical stress on the EM damage of the electronic line. As the results of current loading tests, the specimens with bending deformation became open circuits in shorter time than that without bending deformation. Therefore, it is considered that the bending deformation is affected on the electric reliability characteristic of the flexible electronic lines reflecting EM damage.

Abstract Flexible printed circuits (FPCs) are widely used in electronic devices such as movable part line or wearable sensor. Photolithography is one of the most popular processes for fabricating electric interconnect lines. However, inkjet printing has attracted attention because the method can draw an arbitrary-shape electric lines without any mask. Therefore, nanoparticle metal ink is widely used for printing of conductive electric lines with lowering cost and small-lot production. The physical characteristics such as flexibility or durability of metal nanoparticle ink lines have been evaluated by bending or tensile tests. By contrast, the evaluation method has not been sufficiently established for the electrical characteristics of these lines, and the failure mechanism under high-current density has not been clarified. According to scaling down of electric devices, current density and Joule heating in device lines increase and electromigration (EM) damage becomes a serious problem. EM is a transportation phenomenon of metallic atoms caused by electron wind under high-current density. Reducing EM damage is extremely important to enhance device reliability. In this study, current loading tests of metal nanoparticle ink line were performed to discuss damage mechanism and evaluate electrical reliability under high-current density condition. As the results of current loading tests, the thickness of cathode part of straight-test line was decreased. It is considered that atomic transport from the cathode to the anode occurred by EM phenomenon. The line surface became rough and aggregates of particles generated at middle or anode parts of straight-test line by high-current loading. Both of atomic transport and aggregate generation were closely related the changes of potential drop, their dominances were varied depending the current density value.

To allow for optimum operation of the secondary system of lines, it is essential that the performance of the system be evaluated. Optimal functioning refers to the most desirable and favorable system of operation such as: improved system reliability, adequate and satisfactory electric potential profile, no imbalances in the phases of electric potential and electric charge, complete absence of overloading of electrical conductor used and energy converting devices and approved and allowable loss. This investigative research assesses the efficiency of the distribution system of lines resulting from electric potential deviation, electric potential imbalances, electric potential losses and electric potential fluctuation through the use of MATLAB/Powerlib tools. This research offers most desirable and favourable assessment of Typical, Sub-Saharan Africa secondary unbalanced system of lines. The system of lines was designed with approved and accepted system of line parameters for secondary Sub-Saharan Africa typical system of lines through the use of MATLAB/Powerlib software. The desire outcome got from the MATLAB model with the 500 meters distance for unbalanced system of lines is within permitted actual electric potential limit of minus five per cent for electric potential loss, plus and minus five per cent for electric potential deviation, electric potential imbalances is less than 2 per cent, and the electric potential profile at the end users is within 0.95 and 1.05 per-unit.

Resumo:

Electric road systems (ERS) enable dynamic charging—the most energy efficient and economical way to decarbonize road vehicles. ERS draw electrical power directly from the grid and enable vehicles with small batteries to operate without the need to stop for charging. The three main technologies (i.e., overhead catenary lines, road-bound conductive tracks, and inductive wireless systems in the road surface) are all technically proven; however, no highway system has been commercialized. Electric Road Systems for Dynamic Charging discusses the technical and economic advantages of dynamic charging and questions the current investment in battery-powered and hydrogen-fueled vehicles.

Resumo:

Research into the induction and conduction coupling response of a pipeline co-located with an electric power transmission line to assess the high voltage coupling response under fault conditions. Capacitive discharge tests were performed on primarily fusion bonded epoxy and coal tar enamel coatings containing discrete individual holidays (circa 1985). A pipeline coating response model to high voltage stress was developed, but questions arose within the pipeline community as to the veracity of capacitate discharge coating testing when the coupling was from overhead alternating current electric power transmission lines.

Electric and natural gas utilities often find it advantageous to share rights-of-way. Available methods for evaluating electrical effects on gas pipelines have been difficult to use at best, and at worst, incorrect. A generalized approach that addresses inductive and conductive interferences has not been available. Initiated to fill that need, this work is part of a research effort cosponsored by EPRI and the Pipe Line Research Council International, Inc. (PRCI) �A generalized approach to the analysis of the effects of transmission line faults on natural gas transmission pipelines has been developed and is presented in this report. A state of the art user-friendly computational tool has been developed and verified for the analysis of interference between electrical power lines and nearby buried or aboveground pipelines. This computer program, ECCAPP, is distinguished by its ability to model and analyze accurately complex, realistic interactions between pipelines and power lines, using easily obtained input data. The final report consists of three volumes. An independent fourth volume was also developed to simplify the installation of the ECCAPP software.Volume 1 contains the theory upon which the ECCAPP computer program is based. A parametric analysis and graphical charts have been formulated using ECCAPP to permit estimates to be made in the field or during preliminary analyses for situations that are not too complex. A discussion of various useful mitigation methods is included. The discussion is based on previous research work and on the results of the parametric analysis.Volume 2 is a detailed user's manual which describes not only how to use the program itself, but also which engineering data must be sought during an analysis and how to assimilate it into a computer model. A detailed sample problem is included. A detailed \Glossary of Terms\" used by ECCAPP as well as suitable input data forms to be filled by power line and pipeline engineers are provided in the appendices.Volume 3 discusses the modeling and performance of pipeline insulation or coating.

The economics of high voltage direct current for long-distance transmission of electrical energy have been reported as very attractive, to the extent that several projects are in the making. Several reasons other than the savings in transmission costs, for example the exchange of peak power between time zones and seasonal zones, would permit utilities to save on plant investment for generating capacity while maintaining a high level of service. This report summarizes work on the initial phase of a study to determine the effects of high-voltage direct-current (H.V.D.C.) electric transmission lines on buried pipeline systems. Pipeline Research Council International, Inc. initiated this work in response to an anticipated threat posed by the Pacific Northwest-Southwest Intertie H.V.D.C. system now being designed (and other possible H.V.D.C. lines in the future) because of the announced plans to pass direct current through the earth. The objectives of the overall program are:(1) To determine the nature and magnitude of problems that will be created by the earth current from H.V.D.C. systems, and(2) To devise means of protecting pipelines from the effects of such currents. A computer program was written based on a mathematical model of a buried pipeline in the environment created by an H.V.D.C. system. Excellent agreement was obtained between computed soil potential gradients and measurements obtained during a field test of H.V.D.C. in Oregon. Reasonably good agreement was also obtained between measured pipe-to-soil potentials on the Pacific Lighting Gas Supply Company pipeline near Camino, California, and computed values during a field test of H.V.D.C. power transmission.

Resumo:

Major advances have been made in recent years in the production of electric resistance-welded (ERW) and high-frequency induction (HFI)-welded line pipe, particularly in the area of automated process control procedures designed to ensure uniform, high-quality seam welds. ERW/HFI pipe produced from microalloyed, controlled-rolled steels can be obtained in larger diameters and heavier wall thicknesses than were formerly available, and with reportedly excellent seam-weld quality as well as pipe body properties. Thus, it is feasible to consider the application of ERW/HFI pipe in a number of additional applications in gas-transmission lines. The lower cost of the ERW/HFI pipe compared with double submerged arc welded (DSAW) pipe of comparable size has resulted in increased interest in the greater use of this product. This work was undertaken to determine whether the seam weld quality of modern ERW/HFI pipe has been improved to justify more widespread use, particularly in critical locations, with resultant reductions in construction costs. The report describes the test protocol and results from six samples ranging from X60 through X70 pipe provided by PRCI member companies. Variations in weld zone properties in one of the samples are reviewed and attributed in some detail.

In recent years, several pipe mills have produced heavy-wall, large diameter pipe from plates of microalloyed steels that were controlled-rolled to develop properties to meet the API 5LX Grade 70 or Grade 80 requirements and that were electric resistance welded (ERW) using advanced techniques. The use of advanced electric seam-welding practices on the steels produced using advanced steel making and processing methods offers the possibility of obtaining high strength line pipe at a lower cost than pipes produced from similar steels but with double submerged arc seam welds. The present study was undertaken to evaluate the properties of the pipe body and the ERW seam-weld region of a recently produced heavy-wall X70 line pipe. This report describes the evaluation of that pipe. The mechanical properties of the weld zone from this pipe were evaluated and reported under Task 18-89. Those data are included in this report. A high-frequency electric resistance welded (HFERW) X70 line pipe was evaluated to assess the strength properties, fracture behavior, thermal stability, and susceptibility to environmentally induced degradation that may affect its behavior in gas transmission service. A 20-inch-(508 mm)-diameter by 0.500-inch-(12.7 mm)-wall high-frequency, electric-resistance-welded (HFERW) X70 line pipe was evaluated to assess the strength properties, fracture behavior, thermal stability, and susceptibility to environmentally induced degradation that may affect its behavior in gas transmission service. The steel from which the pipe was produced was processed using advanced steel-making practices that resulted in a low sulfur content and was microalloyed with Cb, V, and Ti. The steel was controlled rolled with 75 percent of the rolling reduction being accomplished at temperatures below 1418 F (770 C); the finishing temperature was 1328 F (720 C) and the steel was hot coiled after finishing. The seam weld was produced by high frequency electric resistance welding and the seam weld region was post-weld normalized.
