Abstract :
A power apparatus applying superconductivity is operated in a specific environment of cryogenic temperature. The conventional solid insulator was not able to maintain its performance of insulation due to its cracking or transformation from contraction under cryogenic temperature. However, GFRP has excellent mechanical and electrical properties even in extremely low temperature, so it has been frequently used as a bobbin or insulator for the superconducting power apparatus such as the superconducting transformer, fault current limiter, and HTS SMES. In this paper, we has investigated the electrical characteristics of insulation according to the thickness and shape of GFRP.
