As expectations have risen about the deployment of smart grids, it is important to investigate the diffusion process of smart equipment such as smart meters, photovoltaic generation, and electric/hybrid vehicles. However, since the revealed preference data have not been accumulated for smart equipment diffusion, this paper conducts a conjoint analysis to examine consumers’ stated preferences on...

The operation of the electricity sector has resulted in more sophisticated equipment and requires more attention from operators. This results in increased cognitive load and environments more conducive to error, which can cause failures that result in significant economic losses, physical damage, or threats to human life. This research aims to evaluate the workload of the operators in two Elect...

This is a collection of reports that consists of three parts. The author is a Professor of Power Electrical Engineering, so he focuses on the Tu-154M power electric system and all aspects of the air crash that relate to electrical equipment and wiring. Part I discusses the electric power system of the Tu-154M. After brief introduction to aircraft electric power systems, the results of reverse d...

objectives: the purpose of this study was to evaluate whether intra-canal application of controlled direct electric current (dec) could accelerate the amount of orthodontic tooth movement (otm) in young adult mixed breed dogs. methods: fourth premolars of both jaws of five young adult mixed breed dogs were divided into two groups of control and experimental groups. orthodontic force was applied...

Failure and circuit upset of electronic equipment due to transients is a problem now and is one which has promise of becoming more of a problem in the future as trends continue toward miniaturization and circuit complexity. Protection methods are used more or less extensively and often haphazardly. At present, there does not appear to be a clear approach toward achieving compatibility between t...

− One of the most applied procedures for detention of incipient faults in power transformers, such as partial discharges, electrical arcing and overheating, is the analysis of the concentration of gases dissolved in the isolating mineral oil. This analysis usually is carried through in a laboratory through chromatography in gaseous phase. Although it presents trustworthy results the chromatogra...

This paper presents an outline of the handling and recycling of SF6 mixtures in electrical power equipment. It is based on the CIGRE Guide for SF6 mixtures and addresses the application fields of SF6 mixtures in electric power equipment, their insulation and switching performance, the evaluation of their environmental advantage, and the processes and equipment for their environmentally responsi...

In power systems, graphical representations of the electric networks are systematically used when designing and operating a network. Being able to visualize the elements of a power system in a two-dimensional space is of paramount importance at these two stages of power system analysis and control. The graphical representation commonly used by all the Transmission System Operators (TSOs) is bas...

Automation and computerized control of processes in electric power plants were intensively started at the end of seventies and at the beginning of eighties during the introduction of microprocessor–based computer systems. The first generation of the information processing equipment has in most cases already become disused. From that time, visibility of controlled process has been increased by i...
