At high temperature and high electric field, the accumulation of space charge would take place in epoxy resin which is used in ultra-high voltage direct current (UHVDC) dry bushings. The space charge accumulated would distort electric field distribution in epoxy resin under polarity reversal voltage. The epoxy resin samples were cast in vacuum condition. At different temperatures, the epoxy resin...
The optimization method combining Finite Element Method (FEM) and particle swarm optimization (PSO) algorithm has been applied to design of corona ring structure for composite insulator used along Ultra High Voltage (UHV) transmission line in the present work. Firstly, corona discharges have been investigated by means of ultraviolet imager (UVI) observation which indicates improper corona structure...
In this paper, the voltage-sharing performance of MOA (metal-oxide surge arrester) for 1000 kV UHV GIS is discussed using the secondary development of the finite element and boundary element numerical method by 3D simulation, ensuring the non-uniform rate of the voltage distribution can be controlled within 10%, reaches the requirements of electric field distribution and the voltage distribution on...
