So far the reported literature on the magnetic fault current limltcr(FCL) arc based on series biasing mode in which the flux due to Hue current flows through the permanent magnet, As a result there ta a high possibility of demagnetization of the permanent mngnet. A passive Cault current limiter lu a combination or passive elements such a.s permanent magnet and saturablc core. Permanent mngnet Is used to bias (he core, In order to avoid severe demagnetization of permanent magnet, in this paper we have Investigated the performances of passive fault current limiter based on permanent magnet nnd saliirablc core In parallel biasing mode, the functional characteristics have been analyzed by Tableau approach and the simulation results arc presented. The experimental results for a small scale prototype model are also presented for verification.
