Summary
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, glass fiber reinforced plastics (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, the authors have investigated the electrical characteristics of insulation according to the thickness and shape of GFRP. In conclusion, a rod shape showed worse insulation properties than a plate shape. As a plan to complement this point, a shape using collars was effective. A shape applied collar is a useful element to help flashover discharge improve withstand voltage. And regulating the ratio of thickness to collars can expect better insulation performance.
