  • Arc protection system and method to control arc protection system
    Patent number: 11368008
    Abstract: Provided is an arc protection system in which an arc remover does not operate in a case of a phase-to-phase short circuit fault or a ground/earth fault among arc faults in a distribution panel, the arc protection system including a sensor configured to sense an arc fault of a distribution panel, an arc removing unit configured to ground a fault current, and a control unit connected to the sensor and configured to measure a short circuit current value of the distribution panel, wherein when the arc fault is sensed and the short circuit current value corresponds to a three-phase short circuit current, the control unit drives the arc removing unit, and when the short circuit current value is smaller than the three-phase short circuit current, the control unit does not drive the arc removing unit.
