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本数据集为实验室测得的非均匀直流电场下大气空气的击穿（火花放电）电压。包含两种火花间隙组件（带微米级调节的小间隙、带遥控位移调节的大间隙）、三种电极材料（黄铜、钢、钨），电极兼具尖锐与钝形两种几何形状，覆盖两种电极极性，电极间距范围为0.01 mm至约40 mm。每一组（材料、形状、极性、间距）组合均进行了15次重复测量。每次测量过程中均记录了环境温度、气压与相对湿度。本数据集随附于学位论文一同提供。
