Settings [ARC-MANOLK]=FT/TPAR/SPAR&TPAR in [MPAR-MODE]=M3
Table 2.34-14 shows the operation results when the setting [MPAR-MODE] is M3 (i.e., ‘M3’
means that three unfaulted (healthy) phases exist in the parallel lines; the respective
unfaulted (healthy) phases are different). For setting [ARC-MANOLK]=SPAR&TPAR, the ARC
function operates to recluse the CB in the SPAR scheme when a faulted phase is found in the
paralleled lines.
Table 2.34-14 Tripped phases and mode for CB reclosing in [MPAR-MODE]=M3
TRC tripping with [TP-MODE]=PER-PHASE → ARC reclosing mode with setting [MPAR-MODE]=M3
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
SPAR: To issue a reclose command by ARC_SPAR_COND
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
