Envisaging links between fundamental research in electrical insulation and electrical asset management

The trend of industrial and even institutional funding for research in the electrical energy world is going clearly in the direction of short-term, applied projects. On the one hand, this may be unavoidable with globalization and the fast increase in the energy needs of developing countries, while on the other hand it may affect in the long term the capability of developing base research in a sector that requires, more than many others, innovation and interdisciplinarity. Research financial institutions, such as the EC, EPRI, CRIEPI, etc., are going in the direction of promoting applied work. This can be seen with favor as long as it can correct distortions of the past, when fundamental research had been seen sometimes as a permanent exercise of speculations without oversight for an applied end; but the risk is to lose the fundamentals of knowledge which is the only way to promote real and stable innovation.     

Polyethylene under electrical stress

Fifty years ago, the concept of an intrinsic electric strength for insulating solids was fashionable. It was supported by the sophisticated theoretical models of von Hippel, Frohlich and others for the interaction of electrons with crystal lattices in an electric field. The models came to be applied, rather implausibly perhaps, to polymers such as semi-crystalline polyethylene (PE). In that climate, the work of van Roggen on the high-field conductivity of single lamellar crystals of PE was notable. Since then, the picture of the insulating properties of PE has had to be painted with an increasingly complex palette in which the electrical elements have had to be supplemented by mechanical, chemical, and optical ones. The present review of the conducting properties of the polymer considers these other features, but concludes that the fundamental characteristics of the lamellar PE crystal are still the determining factors.     

Partnerships for electrical safety

The authors present a case study of the successful development of an educational partnership between industrial collaborators and university researchers to promote electrical safety. For industrial and academic organisations considering a similar approach, we identify a development methodology to align people and resources to implement electrical safety education. Educational partnerships offer a bridge to speed the movement of technologies and concepts between different communities like those represented by a plant and a local hospital. This case study reviews the development of a direct R&D technology transfer educational project targeting electrical safety. Motives to partner were: to become more creative; to identify the best process and best practice; to facilitate the availability of the best care/treatment for those injured on the job through rapid technology transfer; and to specifically move electrical safety principles to a higher level of awareness for individuals, their workplaces, and their communities     

Response to electrical stimuli

Electrical safety is important in industrial work. This article provides considerable detail on how current can pass through different parts of the body and each parameter that can impede or limit the flow of current. Electric currents flowing through a human body can have varying effects, ranging from little or no perceptible effect, to shocking sensation, to possibility of electrocution, depending primarily on the magnitude and the duration of the current flow. The effect of current flow is a function of the applied voltage level, the duration of the exposure, and the resistances or impedances of the body and the other available current paths. A key consideration with energized objects is that, in order for the electric current to flow through the body, one body part must make contact with an energized object or conductor and another body part must make contact with the earth or an object or conductor that provides a path for the current to return to its source. This article supplies considerable detail on how currents can pass though different parts of the body and each parameter that can impede or limit that flow of current. The information presented indicates that the most likely scenarios for a dangerous condition would be that when a person comes in contact with an energized metallic object energized at 120 V and the person is barefoot and the ground is moist or wet as are the persons' hands or feet. Nearly, any other condition such as dry ground, rubber, or leather soled shoes; dry hands and so on have a lower probability of creating current flows that would be considered damaging or disruptive.     

Thermodynamic model for electrical tree propagation kinetics in combined electrical and mechanical stresses

In this paper we develop a kinetic model for the growth of electrical tree structures in solid polymeric insulation that allows for combined electrical and mechanical stresses. We present an energy balance analysis during the tree growth process and show the total tree extension driving force is not a material constant due to the existence of a damage process zone around the tree tip and the dissipated heat and the trapped energy remaining in the damage process zone. We derive both the tree growth rate equation and life formula of tree propagation to breakdown, based on the specific tree growth mechanism and the fractal nature of tree structures. We perform electrical tree growth tests in epoxy resin samples with and without mechanical residual stresses, and present results which show that the proposed model can give predicted tree propagation times to failure in good agreement with the experimental data of the tree growth subjected to a combined electrical and mechanical stress     

Local heating of electrical pathways of power electrical equipment under emergency conditions and overcurrents

Based on the positions of classical and quantum electrodynamics, this paper shows that when a direct, alternating or pulsed current of high density (100 A/mm² or more) flows in emergency situations through metal electrical pathways of power electrical equipment, such electrical pathways in areas of their narrow “hot” longitudinal sections may experience intense local heating. It was found that Joule heating temperatures, which occur in this situation on the “hot” longitudinal sections of the electrical pathways due to periodic localization of electrons on them, are higher by up to 3.5 times than the corresponding temperatures on their adjacent “cold” sections and may lead to electrothermal destruction of these electrical pathways. Experiments confirmed the main results of calculations.     

Engineering your electrical engineering education

Electrical and computer engineering (ECE) courses are usually structured in such a way to provide the student with the basics to solve problems in the field and then challenge the student with increasingly more difficult problems to effectively stretch those basic problem-solving approaches into more advanced techniques. While most of this problem-solving focus is placed on the technical arena, this is only one part of the educational experience for an ECE student. There are many nontechnical facets to one problem-solving repertoire that require development to become a successful practicing engineer in industry or academia after graduation. This article serves to provide some of these facets in a career-direction informational guide to junior- and senior-level undergraduate students and graduate students early in their ECE career. It also serves as a guide to outline some useful strategies not found in an engineering text to maximize one's educational experience at the undergraduate and graduate levels as well as the transition between them.
