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...
In this paper, vacuum-cast epoxy-alumina nanodielectrics are reported with particular attention to the formulation and processing of the samples. Four grades of alumina nano-fillers with different particle size and surface treatments were compared. The samples were fully characterised in terms of their structure, mechanical, thermal and dielectric properties. The characterisations included: nano/micro-structure...
The emergence of UHV AC/DC transmission systems and the installation of UHV equipment in heavily-polluted and high-altitude environments places challenges on the improvement of insulation systems. Part of the challenge can be met by the introduction of new dielectrics that offer superior properties. In particular the development of polymer-based systems that incorporate nano-sized fillers may allow...
Coaxial connectors are used extensively in cables and microwave components. Any losses or reflections are detrimental to a microwave or RF system as they reduce the power transmitted and they become a source of noise thus reducing the overall system Signal to Noise ratio. In this paper a new type of connector is being introduced which avoids step discontinuities by incorporating smooth transitions...
