- Abstract
- High voltage cryogenic insulation issues need to be addressed in order to promote the commercialization of high temperature superconducting (HTS) equipment. As a fundamental step in the development of the optimum bushings for HTS devices, the breakdown characteristics of liquid nitrogen mixed with liquefied insulating gases such as N2, SF6, and CF4 have been investigated. In order to investigate the possibility of substituting CF4 gas for SF6 gas for the bushings of HTS electrical equipment, AC withstanding voltage tests have been performed. In this paper, finding the maximum electric field Emax using utilization factor. This result is applicable to developing the real scale HTS equipment of the design parameters.
