This article highlights the development of electrical apparatuses based on second-generation high-temperature superconducting (2G HTS) wires, such as superconducting cables and superconducting fault current limiters (SFCLs), from a global perspective. While transmission SFCLs have been developed and installed in Russia, superconducting cables have been commercialized, constructed, and operated between the Shingal and Heungduk substations in South Korea. Since high voltage is required to operate SFCLs and superconducting cables, there is a potential risk of electrical breakdown. Thus, studying the dielectric characteristics of liquid nitrogen(LN2), which is commonly used in these apparatuses, is crucial However, previous research on the dielectric characteristics of LN2 has been limited to narrow gaps. To address this research gap, measurements of electrical breakdown for saturated LN2 were conducted under broad conditions. The findings of this study can be applied to the electrical insulation design of high voltage HTS power apparatuses ensuring high stability.
