Nanodielectrics in Power Engineering: Review and Prospects

Nano-dielectrics are materials in which filler particles are dispersed to improve material characteristics such as toughness, enhance barrier properties, and increase resistance to fire. Nano-dielectrics, are expected to have improved dielectric properties which can be exploited with simpler manufacturing technologies, but have a wake of disadvantages. The engineering challenge is to maximize the former and minimize the latter. Nano materials are used or likely to be used in the near future in a large variety of applications in power industry, energy storage devices, and microelectronics, rotating machine insulation, electric stress control applications, and outdoor insulation. In this topical review the author discusses the progress achieved so far, challenges and prospectives in the area of electrical power, transmission and Distribution.
