Electrical application of high Tc superconductingsaturable magnetic core fault current limiter

摘要

A saturable magnetic core electrical fault current limiter (FCT) designed with a high Tc superconducting (HTS) DC bias winding is described. The HTS winding is prepared by using a Ag-clad (Bi,Pb)2Sr2Ca2CuO10+x HTS wire. The limiting behaviour of this FCL is investigated, and its electrical application is considered in an electrical power transmission system. The results show that this FCL limits fault currents effectively and is a possible solution for reducing power system fault currents
