“…In order to realize the superconducting electric power system, it is necessary to establish the electrical insulation technique in cryogenic liquids [1,2] which are used not only as a coolant but also as an insulating material. While, the electrical insulation technique at cryogenic temperatures inevitably faces complicated problems.…”

We investigated the area and volume effects on the breakdown strength in liquid helium and liquid nitrogen, and also carried out the statistical analysis using the Weibull distribution. From the experimental results, we quantified the area and volume effects in cryogenic liquids over a wide range of the stressed electrode area (SEA) from 10-1 to 105 mm2 and the stressed liquid volume (SLV) from 10-2 to 105 mm3. Moreover, we examined the electrical insulation design of cryogenic liquids including the area effect and the volume effect and proposed the fundamental flow chart for the practical insulation of superconducting power apparatus. Finally, we pointed out that the stress level and the V-t characteristics should be estimated with considering the peculiar phenomena arising from the cryogenic environments such as the thermal bubble behavior and the quench-induced dynamic breakdown and so on.
