Autoreclose for multi-phase fault
If [ARC-M] is set to "MPAR2" or "MPAR3", only the faulted phases are tripped and the dead
time counter TMPR is started by any of the tripping signals TRIP-A to C. After the dead time has
elapsed, reclosing command ARC is output, based on the status of the linked circuits check
output signal LINK. The voltage check condition can be configured by the PLC function, if the
voltage check and others are required for the reclosing condition.
In other reclosing modes, three-phase tripping is performed and all of TRIP-A to C are activated.
If [ARC-M] is set to "TPAR" or "SPAR & TPAR", the dead time counter TTPR1 for three-phase
reclosing is started. After the dead time has elapsed, reclosing command ARC is output based on
the status of the voltage and synchronism check elements output signal SYN-OP. (The SYN-OP
