<Figure 5-3> Permanent fault for Recloser Sequence
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.

5.2.2 Operation Principle of FI
If there is a fault on distribution line, protection device(CB, Recloser) does tripping to
protect the system. Then EPIC-R300, Feeder RTU, operates Protection function to detect the
fault, through which it is possible to explore fault section. It is a menu to set and manage
related set value. The basic principle of operation is like a picture below. If there is
permanent or temporary Fault, it detects zero voltage with protective device(CB or
