is assigned by the PLC as a default setting.)
If [ARC-M] is set to "SPAR" or "Disable", autoreclose is not activated.
In "SPAR & TPAR" or "TPAR", if the operating conditions of the voltage and synchronism
check elements assigned by the PLC as default are not satisfied during three-phase reclosing, the
TRR is then picked up and reclosing is reset. In "MPAR2" or "MPAR3", if the operating
condition of interlinking is not satisfied, autoreclosing is not activated and three-phase final
tripping is performed in case of setting [MA-NOLK] to “FT”. In case of setting [MA-NOLK] to
"S" or "S+T", it is shifted to other reclose modes and three-phase final tripping is not performed.
Autoreclose for an evolving fault
Figure 2.10.2.2 shows the sequence diagram of autoreclose for an evolving fault when "SPAR &
TPAR" is selected. If single-phase tripping (1
φ
trip) is performed, the evolving fault detection
timer TEVLV is started at the same as the TSPR is started. If no evolving faults occur,
single-phase reclosing is performed when the TSPR is picked up.
Figure 2.10.2.2 Autoreclose for Evolving Fault
As shown in the figure, if an evolving fault occurs before the TEVLV is picked up, three-phase
tripping (3
φ
trip) is performed. If this occurs, the TSPR and TEVLV are reset, and the TTPR1 is
now started.
After the TTPR1 is picked up, three-phase reclosing is performed based on the status of the
voltage and synchronism check elements output signal SYN-OP. If an evolving fault occurs after
the TEVLV has picked up, autoreclose is reset and reclosing is not performed.
In "MPAR2" or "MPAR3", an evolving fault only resets and restarts the dead time counter TSPR
provided the network conditions defined for linked circuits are satisfied, though not shown in
Figure 2.10.2.1.
