A single dc reactor type fault current limiting interrupter for three-phase power system

We propose a single de reactor type fault current limiting interrupter (FCL I) for a three-phase power system, The device uses a single high temperatur e superconducting (HTS) coil that operates in conjunction with a modified h alf control bridge composed of thyristors and diodes connected to a transfo rmer's secondary windings. One variety is an automatic interrupter, which a utomatically blocks fault current through the application of de bias curren t to the bridge. Another is a gate interrupter, which does the same thing b y blocking the thyristor's gate pulses. We will examine the results of vari ous simulations on a new device that both limits and interrupts fault curre nt in a three-phase power system.
