Abstract
Pulsed and permanent sinusoidal transport current have been applied to melt textured Y1Ba2Cu3O7-delta in order to estimate its current limit ation capability. High pulsed transport currents reaching 9000 A (23 0 00 A/cm(2)) crossed a 4 cm long sample. In permanent sinusoidal curren t, 3000 A (7800 A/cm(2)) crossed the sample without showing any resist ive losses. Above the critical current, the transition from the superc onducting to the normal state is strongly abrupt.
