AC losses in hollow BSCCO cylinders used in an inductive fault current limiter model have been investigated theoretically and experimentally. Discrepancies, becoming more pronounced with increasing current, between the experimental results and predictions of Bean's critical state model were observed. A simple procedure of calculating AC losses by taking into account the real form of the E-J characteristics was proposed. AC loss characteristics were employed to evaluate the nominal and activation currents of the full-scale fault current limiter.
