Sparkover voltage of air - measured data

Laboratory-measured breakdown (sparkover) voltage of atmospheric air in non-uniform DC electric field. Two spark gap assemblies (small gap with micrometric setting, large gap with remote-controlled displacement), three electrode materials (brass, steel, tungsten) in sharp and blunt geometries, both polarities and electrode distances from 0.01 mm to approximately 40 mm. Each (material, shape, polarity, distance) combination was measured 15 times. Temperature, pressure and humidity were logged during each measurement. Provided alongside the diploma thesis
