Abstract
To select electrical insulator (insulator) between coated conductor tapes (CC tapes) of two parallel non-inductively wound solenoid type superconducting fault current limiter (SFCL) is a important issue. Insulator is inserted for separation of two parallel tapes. Quench characteristics and recovery time of SFCL are related on insulator and thermal contact condition. Insertion of tape-shape insulating materials is a normal way of insulation for non-inductively wound SFCL. Thus, various tape-shape insulating materials can be the insulator of SFCL. In this paper, sample holder to simulate parallel tapes with various insulators was fabricated, and sticky polyimide tape and insulating paper tape were chosen for insulator of samples. Short-circuit test was performed in the same condition except inserted insulator of samples. Quench characteristic, generation of resistance, and recovery time of each sample were compared to the others. Special sample holder was used to observe current division and sharing in two parallel coated conductor tapes. The variation of the voltage applied to the module for short-circuit test was from 1.82 (V) to 12.7 (V).
