Abstract :
The influence of the startup instant of the quench in a superconducting current limiter is studied. The heat transfer equation is numerically solved, using the finite difference method, and taking the effects of current sharing into account. The results show the importance of this instant on the dissipated power, the temperature-increase and on the efficiency of the current limitation
