DC reactor effect on bridge type superconducting fault current limiter during load increasing

In high power applications, the fault current limiter has been discussed for many years because of some limitations of conventional circuit breakers. Many types of fault current limiter have already been introduced in papers. In this work, a simple bridge-type fault current limiter has been designed and constructed. The performances of the limiter have been tested successfully. In the bridge-type current limiter, a DC reactor appears in the line when the connected load is increasing. This causes a voltage drop across the load terminal during load changing. The DC reactor effect of the current limiter has been studied. Some experimental results regarding the reactor effect of the limiter have been considered and compared with the results obtained from computer simulation.
