Abstract:
Abstract The paper shows a new idea of aluminium alloys. New alloys with specially selected alloying element i.e. silver have electrical conductivity similar to pure aluminium at ambient temperature and better than pure aluminium electrical conductivity at increased temperatures. Al-Ag alloys for electrical applications (mainly for electrical conductors) due to high electrical conductivity at increased temperatures at the level of the maximum conductor working temperatures give possibility of better current capacity of conductors. The experimental results of basic mechanical properties and the electric conductivity versus temperature relation are shown in the paper as well as examples of the tested material operational properties. The summary gives theoretical analysis based on examples of the potential applications of Al-Ag alloys (new conductor designs) which provide the benefits of the new solutions in comparison to traditional conductors.

Abstract:
In this paper, we present some results of investigations carried out in the electric field distribution of both horizontal and vertical lightning conductors in the case of discontinuous earth. The conductors may be situated as well as in the upper or the lower earth part. The electric field distribution was determined in the case of lightning conductor situated between the high voltage rod and the discontinuity (interface) and also in the case of high voltage rod situated between the lightning conductor and the discontinuity. In some situations the electric field distribution on the plan are smaller than defined by the electro-geometrical model. We attribute this result to the great field intensity at the discontinuity, which reduce the lightning conductor discharge capture effect. This is in concordance with the results concerning the electrical strength of such air gaps without lightning conductors.

Abstract:
This paper concerns about a failure analysis of an electric all aluminum alloy conductor (AAAC) damaged and broken for fretting fatigue phenomena induced by aeolian vibrations. Life of electric conductors is often reduced by various degradation mechanisms such as repeated bending, fluctuating tension, distortion, fatigue, wear and corrosion phenomena. However the main limiting factor of the electrical conductors is related to aeolian vibrations in the high frequency range (between 5 to 50 Hz). Conductor oscillations may lead to fretting fatigue problems (otherwise called fretting wear) caused by wind excitation, mainly in the suspension clamp regions, spacers or other fittings. The induced aluminium wire fracture imply a drastic reduction in the transmission line service. Vibration dampers are considered the most effective method to extend service life of electric conductors, as they are the means to reduce fretting damage of aluminium wires. The aim of the present work is to investigate the failure of an AAAC conductor of a 400kV overhead transmission line (twin conductors) located in Touggourt Biskra (Algeria); the damaged and broken conductors were operated in-service only for six months without spacers or dampers. Three different types of conductors have been taken as experimental samples: the in-service broken conductor, another in-service damaged conductor and a new conductor from warehouse as terms of comparison. Samples have been analysed to identify the root cause of the failure and to verify the conformity of the conductor elements to the international standards. The investigation has outlined the morphology of the fretting damage: in all cases the fractured wires have shown typical static deformation marks and dynamic fretting wear tangential marks associated with intense presence of Al2O3 debris.

Abstract:
A typical example in courses on electricity and magnetism is that of a conductor carrying a steady current. It is said that the electric field inside the conductor is parallel to the current and that there is no transverse (radial) component of the field. While this is reasonable assumption justified for pedagogical purposes, it is not rigorously true. In this paper, the transverse electrical field is calculated as being different from zero, but negligible from an experimental point of view. For various conductors, the transverse electrical field is a polynomial function from steady current.Keywords : Transverse electrical field, steady current, conductor

This paper analyzed the influence that divided conductor to electrical fast transient burst. Divided conductor may change the magnetic field distribution around the conductor, but accordingly increased conductors electrical susceptance. The mechanism that the disconnecting switch cut off the power line when the no-load current is at peak and electric arc distinguished when the current pass zero and accordingly restraining measure is proposed. The outcome showed that the model can simulate the electrical fast transient burst in capacitive power line and makes it easy to analysis complex power system problems based on simple model. The method is proved to be correct and enforceable by validation of protective measures.

Abstract:
Abstract Power system state estimation is a process of real-time online modeling of an electric power system. The estimation is performed with the application of a static model of the system and current measurements of electrical quantities that are encumbered with an error. Usually, a model of the estimated system is also encumbered with an uncertainty, especially power line resistances that depend on the temperature of conductors. At present, a considerable development of technologies for dynamic power line rating can be observed. Typically, devices for dynamic line rating are installed directly on the conductors and measure basic electric parameters such as the current and voltage as well as non-electric ones as the surface temperature of conductors, their expansion, stress or the conductor sag angle relative to the plumb line. The objective of this paper is to present a method for power system state estimation that uses temperature measurements of overhead line conductors as supplementary measurements that enhance the model quality and thereby the estimation accuracy. Power system state estimation is presented together with a method of using the temperature measurements of power line conductors for updating the static power system model in the state estimation process. The results obtained with that method have been analyzed based on the estimation calculations performed for an example system - with and without taking into account the conductor temperature measurements. The final part of the article includes conclusions and suggestions for the further research.

Abstract:
The results from an experimental study of crosstalk interference between twisted pairs of conductors of an electrical wire bundle model are presented. The aim of the study is to determine the crosstalk interference levels in a shielded twisted pair of conductors when there is heterogeneity in the form of a gap between the shield of bundle conductors and the electrical connector body. The studies were carried out on the electrical wire bundle mockup consisting of shielded and unshielded twisted pairs of conductors. The unshielded twisted pair of conductors was used as a source of crosstalk interference. The shielded twisted pair of conductors had a gap between the shield of conductors and the electrical connector body and was a receptor for the crosstalk interference. To study the crosstalk interference levels, the gap length of the shielded twisted pair of conductors was varied. As a result of the study, the crosstalk interference levels for gaps of different lengths were determined. The effect of an electrically conducting connection made using a jumper in the gap between the shield of a twisted pair of conductors and the electrical connector body of the electrical wire bundle mockup on the crosstalk interference levels was studied. A comparative analysis of the results obtained from measurements of the crosstalk interference levels in a shielded twisted pair of conductors with heterogeneities in the form of gaps of different lengths with the crosstalk interference levels in a shielded twisted pair of conductors with a homogeneous shield is carried out. A conclusion about the need to ensure connection of the shields of electrical bundle conductors with the bodies od electrical connectors without gaps has been formulated.

Abstract:
Dynamic Line Rating (DLR) is a process which electrical network operators can implement to improve efficiency by dynamically adjusting the load capacity as conditions allow. To implement DLR an accurate model of the conductors and their clearances is needed. Airborne LiDAR, while expensive, is the most common method of collecting line data as it is fast and is of high quality. State of the art methods for automatically reconstructing conductors first classify conductor points before fitting conductor models. This approach works well for high tension lines with significant separation between conductors but tends to perform poorly in urban environments where conductors are packed tightly together and surrounded by clutter. The method presented in this article attempts to overcome these challenges by performing an informed search for the conductors, anchored to the utility poles. Before the conductors are classified, their layout and sag are estimated, converting conductor segmentation into a linear problem; and a 3D to 2D projection is used to improve density and simplify clustering. The work also attempts to reduce the cost of conductor reconstruction by utilising lower-cost vehicle-mounted LiDAR. By avoiding point classification, higher precision can be achieved in scenarios where previous methods have suffered from significantly degraded performance.

Abstract:
Background: This article deals with the analysis on improved performance and efficiency of induction motor by using nano composites for stator winding. Methods: The nanocomposites are added with different enamel. Enamel is mostly preferred for induction motors’ winding, due to three main reasons: adhesion, infusion and plaster. To predetermine the plaster and nanocomposite conductor’s behavior when they are used for transmitting AC currents and developing AC magnetic field, a numerical analysis is performed. The total heat losses are determined by the heat run test. Open circuit and short circuit tests are used to analyze the performance and efficiency of the proposed induction motor. Results: The AC losses of composite and plaster conductors having good accord are compared with previous solid and hollow conductors. Analysis of the coil by a composite and plaster conductor shows that the AC losses in low current are lower than the coil, which is wrapped by a solid, and hallow conductors. Due to this reason, composite and plaster conductors are considered advantageous for low and medium power motors. Conclusion: Adding nano composites with the plaster material will help to improve electrical, thermal and mechanical characteristics. The property of enamel can change the lifetime of induction motor. The induction motor winding makes use of nano composites SiO2 and TiO2 with enamel coated.

Abstract:
When repairing and replacing electrical wiring in enterprises, the main difficulty is the lack or poor quality of documentation, plans for conductors laying. Distinguishing wires (cables) and their cores by the color of the shells or using tags attached to the ends is difficult if the shells have the same color and there are no tags. Devices and technical solutions used to identify wires and cables do not allow recognizing conductors without breaking the electrical circuit, removing insulation, and de-energizing the network. Searching for the right conductor is a time-consuming operation. (Research purpose) The research purpose is developing a new microcontroller device for identifying wires using an acoustic signal. (Materials and methods) Literature sources has been searched for devices for conductors identifying. (Results and discussion) The article proposes a method that involves feeding an acoustic signal to a wire at one point and capturing it at another, in order to recognize the desired wire. The article presents results of comparison of the developed microcontroller device for identifying conductors using an acoustic signal with known devices and methods for conductors recognizing. (Conclusions) The article reveals the shortcomings of existing methods and means of identifying wires and cables. Authors performed a theoretical calculation of the sound pressure in the conductor at a given distance. The article presents the calculation of speed of acoustic waves in conductors with different types of insulation. Authors designed a microcontroller device for identifying conductors using an acoustic signal and tested it. It was determined that the device increases the safety of work, reduces the cost of operating internal wiring and identification time; eliminates the violation of wire insulation, the need to disable electrical receivers. The convergence of theoretical calculations and experimental data was shown.

Abstract:
In this project, different molecules have been investigated with the purpose of creating anohmic contact between metals and carbon nano materials. In particular, we considered simplemolecules connecting a graphene layer and a copper-slab. In order to determine the capability of such systems, the electronic structure was computedusing Density Functional Theory (DFT). Structural relaxation was performed in order to findcandidates where the metal and the graphene binds chemically with the hypothesis that thehybridization of the states will induce more states at the Fermi level. Six different molecularchains were tested and three of them were found to chemisorb to the graphene sheet and thecopper surface simultaneously. The electronic properties for these systems were then furtherinvestigated using the density of states (DOS). An overlap density of states (ODOS) wasdefined in order to evaluate the respective contribution of the graphene, metal and molecule. From the DOS analysis, we report that these systems did not form ohmic contacts as the resultshows too few states close to the Fermi level. The most interesting case was using a hexanolchain which had some partially overlapping states seen from the ODOS of the graphenemoleculeand graphene-Cu at the Fermi level. However, these were only small contributions.Further research is crucial in order to find a more suitable molecular chain between thegraphene and the copper for an ohmic contact.

Abstract:
The object of this thesis is to develop a method for calculating the losses developed in steel conductors of circular cross-section and at temperatures below 100oC, by the direct passage of a sinusoidally alternating current. Three cases are considered. 1. Isolated solid or tubular conductor. 2. Concentric arrangement of tube and solid return conductor. 3. Concentric arrangement of two tubes. These cases find applications in process temperature maintenance of pipelines, resistance heating of bars and design of bus-bars. The problems associated with the non-linearity of steel are examined. Resistance heating of bars and methods of surface heating of pipelines are briefly described. Magnetic-linear solutions based on Maxwell's equations are critically examined and conditions under which various formulae apply investigated. The conditions under which a tube is electrically equivalent to a solid conductor and to a semi-infinite plate are derived. Existing solutions for the calculation of losses in isolated steel conductors of circular cross-section are reviewed, evaluated and compared. Two methods of solution are developed for the three cases considered. The first is based on the magnetic-linear solutions and offers an alternative to the available methods which are not universal. The second solution extends the existing B/H step-function approximation method to small diameter conductors and to tubes in isolation or in a concentric arrangement. A comprehensive experimental investigation is presented for cases 1 and 2 above which confirms the validity of the proposed methods of solution. These are further supported by experimental results reported in the literature. Good agreement is obtained between measured and calculated loss values for surface field strengths beyond the linear part of the d.c. magnetisation characteristic. It is also shown that there is a difference in the electrical behaviour of a small diameter conductor or thin tube under resistance or induction heating conditions.

Abstract:
All semiconductor devices need electrical accessibility and thus some form of metal contact is required. This contact may be rectifying or ohmic, but the metals used in the chip construction are often unsuitable for making connections to the outside world. Invariably, layered metallizations are used to make the top metallic layer suitable for wire or tape ultrasonic-thermocompression bonding, usually involving aluminium or gold, or soldering using lead-tin alloys. When a semiconductor device is fabricated, it goes through a number of processes at the end of which it is metallized, passivated, encapsulated, and packaged, or any combination of these. The device engineer knows the structure of the device which will include a number of semiconductor-metal, insulator-metal, and metal-metal interfaces. In order to ascertain the operational reliability of the device, accelerated life-tests and predelivery burn-in or screening (or both) based on life tests are often carried out. This stressing involves operating the device either at high temperatures or at high current densities in normal atmospheric, corrosive or highly irradiated environments, or in environments consisting of combinations of these. The different interfaces in the device may change their characteristics through materials transferred by various means at the different stages mentioned above. The interfacial changes and any resultant alterations in the bulk of the constituting materials invariably alters the electrical or mechanical performances (or both) of the device which is said to have degraded. More importantly, operation of the device at high power levels or at high stressing causes thermal runaway and device failure. The work carried out and described in this thesis focuses on failures which occur in the connective paths, known as lines between individual device internal transistors. Firstly, the operation of the VLSI device in adverse elevated thermal and elevated current density conditions will be described. Whilst the process failure mechanisms under these conditions are well documented and mathematically defined, a new technique involving mechanical stress modelling has been developed to predict failures locations in the Al-Si 1% lines. Secondly, a new procedure has been developed to artificially 'age' VLSI devices in order to observe any degradation which may occur in the connecting paths. Several factors have been identified which can contribute to line degradation. These are high current density, high temperature and high mechanical stress. These factors together give rise to electromigration, resulting in the physical movement of line material, which eventually results in catastrophic line failure. It has been previously thought that only temperature and current density were the controlling factors, but this investigation has shown that mechanical stress has a major influence. A new model to predict electromigration phenomena locations in conductive paths has thus been developed based on mechanical stress, in addition to current density and surrounding temperature.

Abstract:
Due to increasing weight of electrical component and wiring harnesses in a vehicle contrary to the demand of light constructed vehicles as well as the constantly increasing and fluctuating price of copper compared to aluminium’s stable and far lower price, the use of aluminium conductors as an alternative have been promoted.  This thesis work lay theoretical research of the available methods used for electrical connection of aluminium conductors in order to increase the knowledge about the available termination techniques.  Due to aluminium’s characteristics such as lower conductivity and strength, tendency to form oxides and relax over time, differences in thermal expansion coefficient and high potential for galvanic corrosion, there is a risk of deterioration and degradation of the connection if the termination of aluminium conductors is not done correctly without being aware of the challenges when it comes to aluminium connection.  The founded solutions are different welding and soldering techniques such as friction welding, ultrasonic welding, resistance welding, plasma soldering and many other modifications of conventional crimp.  A robust termination system that faces all those challenges and ensure a reliable connection during the entire life length of the vehicle and in order to inhibit corrosion different type of sealing of the contact interface will be required.  In order to evaluate the performance of the founded connection method, testing with evaluation of, tensile strength of conductor to contact attachment, tightness demand, corrosion resistance, vibration and heat evolution at the contact attachment have to be conducted.

Abstract:
Abstract Elevated temperature performance of advanced conductors are investigated with a one-dimensional joule heating model. Step-by-step development and validation of the ampacity prediction model are discussed and results from case studies are provided. A potential advantage of advanced electrical conductors is their relatively low density. Copper — as reference — is compared with carbon-based conductors and copper nanocomposites, on the basis of equivalent volume and equivalent weight. It is shown that while doped carbon nanotube (CNT) conductors may potentially result in an improved conductor compared with copper on a weight basis, ultra-conductive copper (UCC) can outperform copper on both volume and weight bases.

Abstract:
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.

Abstract:
Copper is a traditional material for hollow conductors used in generator stator water cooling. However, stainless steel is a promising and proven alternative for use as hollow conductor material. In 30 years of industry experience, no failures were encountered related to cooling water chemistry with this material. This paper describes the history, electrical and mechanical considerations, water chemistry and materials behavior, and experience with stainless steel hollow conductors. Recommendations are provided on use of high purity water with no restriction on oxygen content.
