Study of Superconducting Fault Current Limiter Using Saturated Magnetic Core

This paper presents a saturated magnetic core superconducting current limiter (SCSFCL) operation simulation results using finite element technique. The superconducting current limiter uses BSCCO tape to produce magnetic core saturation to increase the device inductive reactance, during a short-circuit occurrence, thus limiting the short-circuit electric current. The electrical current limiter presents a limiting factor of 56 % of the prospective electrical fault current during 100 ms. A prototype of this SCSFCL is under construction to be tested in a superconducting laboratory.
