摘要：

So far the reported literature on the magnetic fault curl-ent limiter(FCL) are based on series biasing mode in which the flux due to line current flows through the permanent magnet. As a result there is a high possibility of demagnetization of the permanent magnet. A passive fault current limiter is a combination of passive elements such as permanent magnet and saturable core. Permanent magnet Is used to bias the 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 and saturable core in parallel biasing mode. The functional characteristics have been analyzed by Tableau approach and the simulation results are presented. The experimental results for a small scale prototype model are also presented for verification.
