Digital modelling: An essential tool for UHV and HVDC bushings design

Finite Element Analysis (FEA) has evolved over the years from a purely academic pursuit into everyday product development due to the evolution of the computation power and software developments. Engineering simulation technology allows now the detailed analyses of complex sub-systems in different configurations, combined with physical conditions that equipment faces in the real word. It is shown how FEA is nowadays an essential tool for the optimization of the design from the electrical, mechanical and thermal point of view, with special reference to UHV and HVDC bushings.
