4.1.7.6 System
check
on shot 1 (P543/P545)
The
SysChk on Shot 1
setting is used to
Enable/Disable
system checks for the first reclose
after a 3 pole trip in an auto-reclose cycle. When the
SysChk on Shot 1
is set to
Disabled
no system checks are required for the first reclose which may be preferred when high speed
auto-reclose is applied to avoid the extra time for a system check. Subsequent reclose
attempts in a multi-shot cycle will still require a system check.
4.1.7.7 Immediate
auto-reclose
with check synchronism (P543/P545)
The CS AR Immediate setting allows immediate auto-reclosure without waiting for the expiry
of the settable dead time, provided the check synchronism conditions are met and a fault is
not detected. The intention is to allow the local end to reclose immediately if the remote end
has already reclosed successfully and the synchronizing conditions are met.
This feature applies when the setting is enabled. It applies to all dead times, just for three
pole auto-reclose and just for Live Line-Live Bus condition (plus other check synchronizing
conditions of phase angle, frequency etc).
When set to disabled the relay will wait for the relevant dead time.
4.1.7.8 Discrimination timer setting (P543/P545)
A single-phase fault can result in a single-phase trip and a single-pole auto-reclose cycle will
be started, however the fault may evolve during the dead time to affect another phase. For
an evolving fault, the protection issues a three-phase trip.
The discrimination timer starts simultaneously with the dead time timer, and is used to
discriminate from which point in time an evolving fault is identified as no longer one
continued evolution of the first fault, but is now a discrete second fault condition. If the
evolving fault occurs before the expiry of the discrimination time, the protection will start a
three-pole auto-reclose cycle if permitted. If however, the second phase fault occurs after
the discrimination time, the automatic reclose function is blocked, and driven to AR Lockout.
