Modelling of spring type electrical contacts

This study deals with the characterisation of the electrical contacts used in GIS applications (permanent current flow), both by numerical calculation and experimental testing. The good behavior of an electrical contact is related not only to the choice of the materials but also to its geometry. The optimization of these factors will ensure a good performance of the product. This study shows the influence of materials and geometrical parameters on mechanical force and electrical resistance of the contacts. So, the study will allow the optimization of the contact in order to ensure high performance and a stable contact resistance in time.
