About me

PhD title received in 2017

KTH PhD Project

The PhD project was intended to investigate the fundamental physical processes of streamer initiation and propagation, related to the dielectric failure of liquid and liquid/solid insulating systems, based on non-conventional materials (e.g., oil with nanoparticles, biodegradable oils, engineered cellulose and polymers, etc). The project aimed to gather basic physical experimental data on the streamer inception propagation in non-conventional insulating materials. It also included the identification, analysis and characterization of the main physical and chemical material properties that influence the process of insulation failure. Furthermore, it included the development of macroscopic simulation models to improve the interpretation of experimental results and to predict the insulation performance of the new materials under the conditions typical in power components
