Abstract :
The presence of metallic contamination can seriously reduce the insulation performance of a gas insulated system (GIS). This presentation is focused on the motion of elongated particles, since these particles are considered the ones most frequently found in GIS. The aim of the work has been to learn more about the motion and thereby to suggest improvements to the models that traditionally have been used. With a good model, a more accurate calculation of the motion of a particle and, in turn, a better estimation about its severity in a system can be made.
