CB IS Time
CB IS Time = CB In Service Time. This is a timer setting for which a CB must remain closed (and optionally the line be live) before it is
considered to be In Service.
CB IS MemoryTime
CB IS Memory Time is a timer setting which allows a CB In Service state to be remembered for a short period following changeover of the CB
auxiliary switch contacts to a CB Open state. This may occasionally be necessary for a few types of CB with exceptionally fast acting auxiliary
switch contacts which allow the auto-reclose scheme logic to detect the CB opening before it detects an associated protection operation.
DT Start by Prot
DT Start by Prot = Dead Time Start By Protection action. If DT Start by Prot is set to Disable, a dead time start is not directly affected by
protection operation or reset, but is enabled by other conditions or events (see settings: 3PDTStart WhenLD and
DTStart by CB Op).
If DT Start by Prot is set to Protection Op, the dead time starting is enabled when the auto-reclose initiation signal is received from the
protection. If DT Start by Prot is set to Protection Reset, the dead time starting is inhibited until the auto-reclose initiation signal from the
protection resets.
3PDTStart WhenLD
3PDTStart When LD = three phase auto-reclose dead time starts when the line has gone dead. If Enabled, the line is required to go dead
before a 3 phase auto-reclose dead time can start. If Disabled, dead time can start when other selected conditions are satisfied, irrespective
of line volts.
DTStart by CB Op
If Enabled, a dead time start is permitted only when the CB has tripped. If Disabled, a dead time start is permitted when other selected
conditions are satisfied, irrespective of the CB position.
Dead Line Time
When 3PDTStart When LD is Enabled, and the line does not go dead within the set Dead Line Time period, then the logic will force the auto-
reclose sequence to lockout after expiry of this time.
SP AR Dead Time
Dead time setting for single phase auto-reclose.
3P AR DT Shot 1
Dead time setting for three phase auto-reclose (first shot).
3P AR DT Shot 2
Dead time setting for three phase auto-reclose (2nd shot).
3P AR DT Shot 3
Dead time setting for three phase auto-reclose (3rd shot).
3P AR DT Shot 4
Dead time setting for three phase auto-reclose (4th shot).
Follower Time
Time delay setting for follower CB reclosing after leader CB has reclosed.
SPAR ReclaimTime
Reclaim time setting following single phase auto-reclosure.
3PAR ReclaimTime
Reclaim time setting following three phase auto-reclosure.
