Demand monitoring equipment is installed in each factory or office, and is linked to the Mitsubishi Electric Head Office via the intranet, where a centralized monitoring server provides comprehensive control (Fig. 1). The multi-demand viewer uses its wide-area control function to collect electric power data from each site in real time, and sends out an alert e-mail when there is a high probabil...

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...

Outdoor high-voltage equipment is exposed to moisture, rain and pollution. Water droplets on insulators influence negatively the material-aging process. A numerical procedure is presented which simulates the droplet behavior in a strong electric field. It consists in an iteration over an electric and a mechanical sub-problem to solve a coupled system of boundary value problems on the free domai...

The study bases its analysis on projections that the electric grid will rely more on renewable energy and non-emitting power generation. It corroborates earlier findings that a decarbonizing grid accommodating a fleet of electric vehicles would reduce emissions relative to scenarios in which transportation, industrial and other fleets continue to rely primarily on petroleum fuels. With the wide...

To reduce greenhouse gas emissions, ports around the world are considering using electric cargo handling equipment. To assess the benefits of the strategy, this study provides a comparative life-cycle assessment between diesel and electric yard tractors in a case study of the Port of Los Angeles. Results indicate a significant reduction in life-cycle emissions as the port shifts to electric veh...

Implementing the objectives set at European and national level to minimize dependence on fossil fuels mitigate impact of transport environment by introducing fiscal facilities has led an increase in market for electric vehicles. This requires development expansion charging infrastructure The transition from supply classic fuel vehicles ones elimination some risks appearance new stations’ mainte...

Energy delivery at well construction in regions with hard climate is distinguished by variable demand in electric and heat power. Energy consumption of drilling equipment, production and living facilities varies greatly during the year, depending on power load charts and climate conditions. Power supply of remote well construction sites is mostly accomplished by operating autonomous power sourc...
