Discharge mechanism in CO2 - A study on possible occurrence of secondary discharges caused by field distortion during streamer or leader propagation

MSc - thesis of Suhaib Kappadan

This project aims to investigate a potential new phenomenon, the occurrence of secondary discharges caused by propagating streamer or leader discharges in HV gas insulation. Learning more about such phenomena can help us improve the dielectric design or perhaps explain the occurrence of breakdowns reported in high voltage equipment for which no obvious cause could be found. Specifically, CO2/O2 mixtures will be studied, and its results compared to SF6.
