Abstract
A flux flow resistance type fault current limiter (FCL) suppressing an overcurrent only by the flux flow resistance of a high temperature superconductor (HTS) was proposed. This type of FCL may recover to superconducting state so that a load current is passed immediately after the fault clearing because the flux flow resistance disappears at the moment that the current becomes lower than the critical current. That is an infinitely short recovery may be achieved. In this paper, we carry out a feasibility study on the flow resistive FCL using Bi2223 bulk installed at the outgoing feeder in a 6.6 kV distribution substation. It is pointed out the flux flow resistance type FCL may be realized by using the bulk of about 10-2 to 10-1 m3.
