Abstract
The present disclosure relates to a fault current limiter, comprising: a trigger device dividing a fault current to a path on which a normal current flows and to a path on which the fault current flows when the fault current is generated; a first switch connected in series to a rear end of the trigger device; a fixation unit for fixing an open/close state of the first switch; a driver for opening a contact point contacted by the first switch by repulsive force generated by the fault current in a case the fault current divided by the trigger device is inputted; and a control module for driving the fixation unit in order to fix the open/close state of the first switch in a case the fault current is generated.
