The way to set is identical with 5.2.3
5.2.6. Trip & Reclose
1) Phase Rec Count
This is the menu for setting the counts of reclosing operation against phase fault.
2) GND Rec Count
This is the menu for setting the counts of reclosing operation against GND fault.
3) SEF Rec Count
This is the menu for setting the counts of reclosing operation against SEF fault.
4) Single Shot Operation
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.
5) Sequence Coordination
When operating with 2 or more Recloser connected in series in distribution line, in order
to prevent the operation of all Reclosers’ being opened at the same time which are
installed both in power supply side and in load side, the Sequence Coordination function
is used to. This function is that, when multiple Reclosers in load side are connected to
