According to the characteristics of the aluminum conductors, coated-steel reinforced (ACSR), combined the feature that isotropic and continuity of the folded yarns, establish the calculated equation of the Poisson ratio of the discrete and anisotropic wires. After given the calculated equation of stiffness of large cross-section wires, we obtained the calculated equation of elastic modulus, shear modulus and Poisson ratio. These wires stiffness not only reflect the characteristics of the composite material, but also provide guidance and reference for the mechanical calculation of the wires and installation of overhead conductor and ground wires and the following equation also has certain value in mechanics calculation and lines of construction.

Mechanical deformations when a wire is stretched causes its rotation around its axis, which allows obtaining additional information about the wire behavior in an overhead transmission line and considering it no longer as a group of sections from one span but as a whole interconnected section with redistribution of mechanical loads between spans. To determine the tensile strength of wire by its torsion, a method for determining the mechanical parameters of an overhead transmission line was developed. It is based on the inclinometric method and the theory of force calculation of steel ropes. This technique takes into account the torsion, the angle of inclination and the wire temperature. The technique is implemented in the system for monitoring the status of overhead power lines. It takes into account the torsion angle of the wire and helps to prevent emergencies on the overhead power line by determining the tensile strength of the wire, checking for defects in wires of the overhead power line and defects in the suspension armature. The monitoring system includes control devices, data collection and data processing center, a dispatcher software package. Control devices are installed directly on the wire/ground wire of an overhead power line and are used to measure the angle of rotation, the angle of inclination and the wire temperature. The data collection and data processing station processes them according to the developed methodology in specialized software. The system for monitoring the status of overhead power lines based on the inclinometric method helps to prevent emergencies and reduce the economic costs of maintaining and restoring overhead power lines.

This thesis aims to examine the performance of Stockbridge dampers used to suppress aeolian vibrations on overhead transmission lines arising from the wind. In this respect, a computer program, based on the Energy Balance Method, is developed using MATLAB. The developed computer program has also a graphical user interface (GUI), which allows the program to interactively simulate Stockbridge damper performance for vibration control of overhead transmission lines. Field tests results obtained from literature are used in various case studies in order to validate and evaluate the developed software. Moreover, sample Stockbridge damper characterization tests, which then could be introduced to the software, are performed. A custom test fixture is designed due to its unavailability of commercial alternatives in the market. In the design of the test fixture, modal and transmissibility analyses are done by using ANSYS Workbench. To further validate the test setup, transmissibility test is done and consistent results with the transmissibility analyses are observed in the range of expected aeolian vibration frequencies. Finally, the stepped-sine and swept-sine tests are performed with and without damper for the characterization test, where the latter one is performed to eliminate the negative effects of the test setup. Both tests yield almost same damper power dissipation curves.

This thesis is focused on assessing the impact of retrofitting dielectric All Dielectric Self-Supporting Cable (ADSS) to existing MV overhead line. This type of optical cable is a means of future strengthening of the communication infrastructure of the distribution network. However, its mechanical properties are significantly different from the properties ACSR cable, due to which its installation can be problematic in terms of meeting the requirements of the PNE 33 3301 standard. In practical part, this work deals with the design of the ADSS installation on the existing MV line and the determination of its impact based on the assessment of the results of this design.

Thesis (M. Tech.) - Central University of Technology, Free State, 2011
The objectives of this research were to investigate and establish a procedure to determine the self-damping characteristics of transmission line conductors subjected to free and forced vibrations. The TERN and Aero-Z IEC62219-REV240609 conductor cables were the transmission line conductors that were readily available at the Vibration Research and Testing Centre (VTRC) of the University of KwaZulu-Natal (UKZN). The question to be answered was whether the self-damping characteristics of the TERN and Aero-Z IEC62219-REV240609 conductors were adequate to suppress Aeolian or wake-induced vibrations. In other words, is it necessary for external damping mechanisms to be used with these conductors? This study confirmed that the self-damping characteristics of conductors are not adequate to suppress Aeolian or wake-induced vibrations. Governing partial differential equations describing the characteristics of the catenary and parabolic cable conductors were developed to validate the experimental results. The experimental tests involved both conductors being subjected to an impulse function (a free vibration method) and also to a harmonic function (a forced vibration method). Measurements were carried out using accelerometers, and the recording equipment consisted of oscilloscopes and the PUMA system. With both the free and forced vibration methods, the damping factor of the TERN conductor was confirmed to be ζ ≤ 0.05, whereas the damping factor of the Aero-Z IEC62219-REV240609 was confirmed to be ζ ≤ 0.2. A procedure for determining the self-damping characteristics of the TERN and Aero-Z IEC62219-REV240609 conductors was developed, with the damping factor found to be ζ ≤ 0.2 for both conductors. These methods can assist in the implementation of procedural analysis of the self-damping behaviour of different types of transmission conductors and in finding the most suitable mass absorber (damper) to use in reducing the rate of failure of transmission line conductors. The results of this study can be used to improve the mathematical modelling of Aeolian and wind-induced vibrations where both self-damping properties and a mass absorber are incorporated.

This thesis establishes a rigorous procedure for overhead line uprating with guidance for calculating the increase in voltage rating that may be achieved for given configurations. It initially investigates different technical issues and conventional methods of voltage uprating of overhead transmission lines. Various issues such as clearance, insulation, pollution, transient overvoltages, surge arresters and its combinations were studied for optimised insulation coordination of voltage uprated transmission systems with reference to international standard IEC 60071 and British standard BSEN 50341. It then considers a case of existing 275kV line in 'L3' structures to analyse these issues and propose appropriate process for its possible uprating to 400kV system. In this investigation, overhead line uprating techniques used by different utilities around the world, as published in the literature were analysed. It was found that, the decision to uprate overhead lines is influenced by technical, institutional and financial issues. In this thesis, issues such as conductor air clearance, insulation electrical strength and overvoltages are investigated and taken into account to develop an appropriate methodology. For uprating overhead lines, an exemplar case study of uprating an L3, 275kV line to 400kV was used, introducing minimum structural changes to the tower. The selection of the L3 tower is made on the basis that it is not readily upratable to 400kV due to restricted air clearances it offers. This work has demonstrated that the voltage uprating of overhead transmission lines is possible with minimal modification to the existing line. In this case, the phase-to-earth clearance was found to be the critical factor which determines the level to which the voltage level of the line can be increased. Computations of overvoltages due to switching and lightning phenomena were conducted to estimate overvoltage levels and optimise the protection scheme required to minimise the required minimum electrical clearances. Employing gapless metal-oxide line surge arresters were proposed to be the most effective solution to control the overvoltages, thereby reducing the minimum phase-to-earth clearance requirements. This solution is preferred to modifying the tower structure in order to achieve the required clearance for 400kV system. The study of lightning and switching surge performances along the line under different arrester configurations was carried out so that the appropriate surge arrester configuration could be selected to maintain overvoltage levels within the targeted withstand level for the line. The extensive transient simulations performed in this work identified that, for a double circuit overhead transmission line as used on the UK system, the top-most phase conductors are prone to shielding failure lightning strikes whilst the bottom-most phase conductors are likely to be subjected to backflashover surges for the case of high tower footing resistance. The assessment of electric and magnetic field profiles of a 275kV line uprated to 400kV was computed. It showed that, the field intensities of voltage uprated lines are within the limits adopted by national and international standards and requires no additional wayleave for uprating.

Statnett wants to increase the transmission capacity in their 300 kV overhead lines by upgrading the operating voltage to 420 kV. To make this possible some modifications must be done. Insulator strings have to be elongated by two to four insulators and the air clearances must be checked. EN standards provide guidelines for how to calculate the air clearances adequately to provide required safety margins.It turns out that the formulas given by the standards provide greater safety margin than appropriate for upgraded transmission lines. By finding new proper safety margins, several towers which otherwise would have to be rebuilt to fulfill the requirements for clearances, can stay unmodified. When considering the number of towers in an average transmission line, there is obviously a great potential for saving money by putting some effort looking into proper minimum air clearances. By reduce the air clearance by approximately 10 cm, 6.5 mill. NOK were spared in a 65 km transmission line. It is therefore desirable to calculate the air clearances on the basis of smaller safety margins than described in the standard, but which is still within acceptable safety limits. In the formulas for minimum distances, the statistical withstand voltage U50%, gap-factors and altitude factors are examined for the cases of operating voltage, switching impulse and lightning impulse.Discrepancies between test results from a laboratory work conducted by STRI and calculations based on the EN standard of U50%, have been discovered. Tested U50 for switching impulses are 59 % higher than U50 from the standard. The same applies for lightning impulses where the tested value is 12 % higher than the standard. This gives reason to assume the standard to be somewhat conservative.Further, discrepancies are found between the standard EN 50341 that says that the gap factor when an insulator is present is the same as if no insulator is present, and Cigré report 72, which says that the gap factor should be corrected for the presence of insulators. Correction for insulators will lead to a lower gap factor i.e. lower break down strength along the insulator string than in the rest of the air gap. It turns out that the combination of rain and insulator string reduce the gap factor and thus, the withstand strength in the cases of switching impulses in the order of 6-13 % for V-string insulators and 20-34 % for I-string insulators and for continuous power frequency voltage in the order of 25 % for V-string insulators and 33-40 % for I-string insulators.Rain has no influence on the withstand strength of I-strings or V-strings exposed to lightning impulses.Several previous researches [1][2] shows the same tendencies of lack of correlation between U50 and gap factors when air gaps with insulator strings are exposed to lightning impulses. Thus, the gap factor is not sufficient to describe the discharge characteristics of air gaps with insulator strings exposed to lightning impulses.It is found that the air gap between phase and guy wire has approximately 7 % greater withstand strength than over the insulator string in a tower window. This additional safety margin is a desirable property in terms that the guy wires are the weakest point of a tower. This should however be verified by full-scale laboratory tests as this is mainly valid for the case of only the conductor-guy wire gap without the presence of the other air gaps that represent the tower window.

This Thesis describes a technique for collecting, moulding and testing naturally occurring ice accretions. Faithful reproductions of the ice shapes were cast in silicone rubber from which wind tunnel models were made. They were tested using a specifically designed wind tunnel rig which measured the aerodynamic lift, drag and pitching moment of the models. From the aerodynamic data the gradients of lift, drag and pitching moment of each ice shape were calculated. The aerodynamic data were consequently used in a two-dimensional two degree of freedom theoretical aerodynamic model which included aerodynamic lift, drag, moment, ice eccentricity, conductor wake effects and the mechanical properties of the conductor. Wind tunnel tests were carried out on a specifically designed wind tunnel dynamic rig. Instabilities of the coupled vertical/torsional galloping were established. Regions of instability were also predicted using a two-dimensional theoretical conductor model. The initial theoretical analysis formed the basis upon which a more sophisticated three-dimensional finite element aeroelastic model was developed. The effects of ice and wind on the natural frequencies and the stability of the conductor were investigated. The use of galloping control devices, the pendulum detuners was also examined. Results showed that the pendulums had a stabilising effect in controlling the vertical/torsional frequency ratio of twin bundles. The vibration characteristics and the stability of quad bundles were investigated using finite elements. In this case, the pendulums shifted the torsional frequencies of the bundle to higher values close to the corresponding vertical frequencies, thus enhancing coupling and having an adverse effect on stability. Finally, limitations in the performance of the pendulum detuners were predicted.

Overhead electric transmission lines are subjected to many natural hazards. Presently, the strength and remaining life of the transmission lines have primarily been determined by visual inspection. This paper presents results of our research, which has been focused on the feasibility analysis, and the development of an intelligent monitoring and integrity assessment system without the need for de-energizing or disassembly of transmission lines. This mechatronic system combines advances in electronics, mechanical system design, embedded signal processing and neural networks for signature analysis and feature extraction to create a smart diagnostic system for real-time operation. This paper also presents results from the actual field-testing of the Electromagnetic-Acoustic-Transducer (EMAT) monitoring system from utility companies. The utility companies are currently utilizing the EMAT to identify status of the overhead transmission lines without de-energizing and disassembly of their tower structures.

Nowadays, the electricity demand keeps increasing. To adapt to this request, an increase in the production of electricity, as well as in transmission and distribution capacities is necessary. Whereas the construction of a new site of energy production is relatively easy, it is extremely long and difficult to manage to build new overhead lines. Consequently, electricity companies are searching for means to maximize the transport capacity of their lines while preserving the minimal distances to the ground and the mechanical reliability of the lines. Real time monitoring of the line ampacity is one of the means which make it possible to optimize the use of high voltage lines.

Overhead electrical transmission lines are always susceptible to aeolian vibrations, caused by light to moderate winds. Spacer dampers are used in bundled transmission lines to keep the conductors at required minimum spacing and to suppress the wind induced vibrations. Mathematical models are necessary for the computation of the conductor vibrations for studying the efficiency of damping measures. The so called energy balance method gives good results for estimating the vortex excited vibrations of overhead electrical transmission lines. In its standard form it requires the knowledge of the eigenfunctions, which are routinely calculated for the single conductor lines. However, the problem becomes more involved in the case of bundled conductors with spacer dampers due to very dense spectrum of the natural frequencies. In the present paper some approaches towards solving the transcendental eigenvalue problem (EVP) for the bundled conductors with spacer dampers are discussed. It is formulated as an algebraic transcendental EVP, which however presents several numerical difficulties. Reasons for these numerical difficulties are discussed in some detail. A new approach, named as “continuous spectrum approach,” provides better engineering solution for the transmission line bundled conductors. The solution of the EVP gives the necessary input data for applying the energy balance.
