Summary Advanced optical diagnostics of vacuum arc plasma for switching applications Vacuum technology provides environmentally compatible and emission‐free solutions for switching in power grids. A high number of operations under standard load conditions, safe and reproducible short‐circuit current interruption capability, and maintenance‐free operation are few examples of advantages of vacuum circuit breakers. Further development of such devices requires fundamental knowledge about the switching process and interaction of materials used with the working medium – the vacuum arc plasma. The optical diagnostics offers numerous methods for the characterization of the arc plasma and surrounding components, like e.g. electrodes and chamber walls. Studies of plasma and electrode phenomena by combination of optical and electrical diagnostics allow for material qualification, choice of design and arc extinguishing mechanisms.
