Fault Current Characteristics of a Bi-2223 Tape

Bi-2223테이프의 사고전류 특성

Temperature and resistance of a Bi-2223 tape for fault currents up to 10 $I_{c}$ were measured in two types of samples taking into account real applications. The results indicate that the Bi-2223 tape is safe from burn-out for fault currents with a few cycles up to 10 I$_{c}$. For fault currents of over an order of magnitude higher than the nominal current, the temperature of the Bi-2223 tape depends strongly on fault durations.s.
