Settings [ARC-MANOLK]=FT/TPAR/SPAR&TPAR in [MPAR-MODE]=M2
Table 2.34-13 shows tripping and reclosing results when the setting [MPAR-MODE] is M2 (i.e.,
‘M2’ means that two or three unfaulted (healthy) phases exist in the parallel lines; respective
unfualted phases are different).
For setting [ARC-MANOLK]=TPAR or SPAR&TPAR, the CB can be reclosed in the TPAR
scheme when the MPAR-LINK condition is not observed.
For setting [ARC-MANOLK]=FT, the ARC function abandons to reclose the CB as when
the MPAR-LINK condition is not achieved in the paralleled lines.

x: Occurrence of the fault
–: Not energized (out of service)
MPAR: To issue a reclose command by ARC_MPAR_COND
TPAR: The TPAR scheme issuing three-phases tripping by ARC_TPAR_COND; then, to
issue a reclose command
FT: To abandon reclosing CB after ARC issuing three-phases tripping by FT setting
1ΦT: To issue a single-phase tripping
2ΦT: To issue two-phases tripping
3ΦT: To issue three-phases tripping
(N.A): Tripping and reclosing do not perform
