About Plasma-Polymer Interaction and Treeing Progression

Partial discharges are one of the main aging mechanisms of electrical components. Some specific types of partial discharges, such as surface discharges and treeing, involve the interaction of a plasma with a polymeric surface. Our aim is to build a multi-scale model that describes the ageing of dielectric materials exposed to these types of partial discharges and can, possibly, shed new light on the treeing progression.
