    Reclosers can break and make currents several times, thus avoiding longer network interruptions due to temporary faults. But, in case of permanent fault, because fault current is still detected after trip and reclosing actions of pre-set sequences, Recloser is locked out finally as opened.

    5.2.1 Operation Principle of Recloser The figure below shows the case of lockout state that, when set with 2F3D of reclosing sequence, Recloser operates twice of fast operation and 3 times of delay operation against fault, and then locked out as opened.

  • Page 42: Operation Principle Of Fi

    The following figure shows the successful reclosing case that Recloser operates twice of fast action and inputted. After the lapse of set-Reset Time, Recloser returns, and then display of LED and LCD are changed from Progress into Ready status. If a fault occurs again during Reset Time, when the counts of reclosing action reaches to total counts which shall be calculated from remaining fault counts, the Recloser becomes locked out.

If FI Auto Reset was set, FI is reset automatically. If not, push FI reset button on the front or it is reset with transmitted FI reset order in remote.

  • Page 45 Recloser is maintained for 5 minutes(300sec). If the measured current is less than the multiples of pick-up, Recloser does not recognize it as a failure. If it is larger than the multiples of pick-up, Recloser regards the situation as an actual fault, and performs the same reclosing sequence same as normal operation.
  • Page 46 When the circuit breaker is putted in order to supply the electricity to a load, Inrush current is generated in a short time. Inrush restraint is a function to prevent Recloser’s mis-operation of fault detection elements due to that kind of inrush current at the time of energization in the line.

  • Page 49: Trip & Reclose

    In single shot operation, Recloser goes directly to lockout after a trip, and will not reclose. This operation occurs in two cases ; one is the case when Recloser disable in the front, the controller goes to lockout without reclosing. and another case is that, after Recloser is put, the fault occurs during the Single Shot setting time, then it goes to trip and locked-out.
