Abstract :
This paper describes and analyzes the transition process to the normal state in BSCCO 2212 fibers grown using a LFZ process. To study this transition a specific installation was developed allowing to test and measure fibers under pulsed operation. The origin and the propagation mechanism of the transition have been analyzed, and models to predict the evolution of magnitudes such as the resistance or the temperature are proposed and verified with experimental measurements.
