报告人简介：

George Chen: IEEE Fellow and IET Fellow. He received his B.S. (1983) and M.S. (1986) in Electrical Engineering from Xi'an Jiaotong University and his Ph.D. (1990) in Electrical Engineering from the University of Strathclyde, UK. He joined the University of Southampton in 1990 as a postdoctoral researcher, became an academic staff member in 1997, was promoted to Reader in 2002, and became a Professor in 2012. He is now Professor of High Voltage Engineering (University of Southampton) and head of the Power Engineering Research Group. He is a member of the IEEE DEIS HVDC Cable Working Group and participated in the development of two IEEE standards on space charging and partial discharge measurements. He is also a member of the IEC TC 112 UK expert to develop the IEC standard on PEA measurements. Leading EPSRC and Industry funded research projects involving high voltage systems and electrical insulation, including developing HVDC cables for industrial partners. Direct supervision of 1 research fellow and 4 PhD students. Successfully supervised 30+ PhD students to completion of doctoral thesis.

报告简介：

Nanodielectrics have been actively investigated in last two decades as they have shown some improved dielectric properties that are important for high voltage insulation applications. One of these improvements is the reduction in space charge when the nanodielectrics are subjected to dc electric fields. The formation of deep trap after introducing nanoparticles in the material has been widely reported. However, the mechanisms that are responsible for the charge suppression are not detailed. This seminar intends to give an overview on nandielectrics and some of our research on charge dynamics in nanodielectrics and their impact on electrical performance.
