High Voltage Laboratory, ETH Zürich

The research and teaching focus of the High Voltage Laboratory is on technologies for future electric power transmission systems. This includes four main fields: high-voltage gaseous insulation systems, future overhead power transmission lines, high-voltage solid insulation, and current interruption. Our projects aim to search for insulation gas mixtures alternatives to SF6, HVDC, and mixed-frequency solid insulation systems, hybrid AC-DC overhead power lines, corona inception and mitigation, and experimental studies to characterize and optimize switching arcs for HVDC circuit breakers and SF6-free breakers.
