High voltage insulation of the heat-resistant polymer composite material mainly composed of synthetic resin matrix, reinforcing materials, inorganic fillers, pigments and other components. In addition, according to the technical and performance requirements will be added in the resin matrix curing agent, thickener, mold release agents, solvents and so on. By different proportions of the resin matrix and filler and other additives, under conditions in certain insulating polymer composites were prepared to explore the relationship between components, the best formula and the ideal insulation material.

ABSTRACTThis paper investigates the development process of emergent materials for architecture by looking at the example of Phase Change Materials. In the context of the complex nature of the constructed environment and the functional and performance requirements for buildings, emergent materials have to be carefully tuned for maximum performance. Investigating the relationship of time, space and matter in the design and development process through interdisciplinary endeavors is at the heart of this investigation. Furthermore, a shift from multidisciplinary endeavors to truly interdisciplinary collaboration that crosses the traditional boundaries of the individual fields is suggested.

High Voltage Insulation

High-voltage insulation space-components are critical to the reliability of traveling wave tube amplifiers on satellite. Unlike in atmosphere, high-voltage components working in space can easily discharge due to insulation molding defects, which will lead to failure of amplifiers. We can solve these problems through adopting epoxy resin matrix composites as filler and applying vacuum-pressure injection molding technology for insulated molding process.

The insulation should be high quality for power transmission and high voltage application, in this way we are studying about the various type of insulation material such as epoxy resin, vulcanized fibres and polyethylene which are having different capacitance value, the power transmission equipment’s has less efficiency due to degradation of insulation material. In this paper, we are studying the partial discharge for the different type of insulation materials.

The development of offshore wind farms (WF) is inevitable as they have exceptional resistance against climate change and produce clean energy without hazardous wastes. The offshore WF usually has a bigger generation capacity with less environmental impacts, and it is more reliable too due to stronger and consistent sea winds. The early offshore WF installations are located near the shore, whereas most modern installations are located far away from shore, generating higher power. This paradigm shift has forced the researchers and industry personnel to look deeper into transmission options, namely, high voltage AC transmission (HVAC) and high voltage DC transmission (HVDC). This evaluation can be both in terms of power carrying capability as well as cost comparisons. Additionally, different performance requirements such as power rating, onshore grid requirements, reactive power compensation, etc., must be considered for evaluation. This paper elaborately reviews and explains the offshore wind farm structure and performance requirements for bulk offshore power transfer. Based on the structure and performance requirements, both HVDC and HVAC transmission modes are compared and analyzed critically. Finally, a criterion for selection and increasing popularity of HVDC transmission is established.

Reactions To Feedback

This paper focuses on explaining how individuals set goals on multiple performance episodes, in the context of performance feedback comparing their performance on each episode with their respective goal. The proposed model was tested through a longitudinal study of 493 university students’ actual goals and performance on business school exams. Results of a structural equation model supported the proposed conceptual model in which self-efficacy and emotional reactions to feedback mediate the relationship between feedback and subsequent goals. In addition, as expected, participants’ standing on a dispositional measure of behavioral inhibition influenced the strength of their emotional reactions to negative feedback.
