Saturable DC reactor type fault current limiter

摘要

PROBLEM TO BE SOLVED: To provide a commercially usable current limiter device by solving various problems in currently proposed current limiter devices. SOLUTION: In this current limiter device with a saturable DC reactor, a DC output terminal of a full wave rectifier inserted in a line between an AC power supply and a load is connected to a primary coil L1 of the saturable DC reactor, and a DC power supply for saturating a saturable core of the saturable DC reactor is connected to a secondary coil L2 .
