Abstract :
Tests were conducted to determine the electrical and magnetic characteristics of a superconductor-shielded core reactor (SSCR). The results show that a closed-core SSCR is predominantly a resistive device and an open-core SSCR is a hybrid resistive/inductive device. The open-core SSCR appears to dissipate less energy than the closed-core SSCR. However, the impedance of the open-core SSCR is less than that of the closed-core SSCR. Magnetic and thermal diffusion are believed to be the mechanisms that facilitate penetration of the superconductor tube under fault conditions
