Characteristics of electrical breakdown in composite insulating systems: Ln₂‐solid interface in parallel or series with the field

High Voltage Insulation Based on Area and Volume Effects of Cryogenic Liquids for Superconducting Power Apparatus

“…In this section, we take other researchers' data into our study and systematized the area and volume effects in LHe and LN2. Table 1 lists the experimental conditions for other researcher's results [10][11][12][13][14][15][16][17]; the used electrode configurations are plane-to-plane, sphere-to-plane, sphere-to-sphere and coaxial cylindrical electrodes. We carried out the electric field calculation by charge simulation method for these electrode configurations and dimensions listed in Table 1, and calculated 75%SEA and 75%SLV for LHe or 82%SEA and 82%SLV for LN2, respectively, according to the discussion in the previous section.…”
