DESCRIPTION
CB IS Time 49 60 5
From 0.1 to 200 in steps of 0.1
[Courier Number (time-seconds)]
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 49 61 0.5
From 0.01 to 1 in steps of 0.01
[Courier Number (time-seconds)]
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 49 62 Prot Res
Prot Res
Prot Op
Disabled
[Indexed String]
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 49 63 Disabled
Disabled
Enabled
[Indexed String]
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 49 64 Disabled
Disabled
Enabled
[Indexed String]
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 49 66 5
From 1 to 9999 in steps of 1
[Courier Number (time-seconds)]
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 49 67 0.5
From 0 to 10 in steps of 0.01
[Courier Number (time-seconds)]
Dead time setting for single phase auto-reclose.
3P AR DT Shot 1 49 68 0.3
From 0.01 to 300 in steps of 0.01
[Courier Number (time-seconds)]
Dead time setting for three phase auto-reclose (first shot).
3P AR DT Shot 2 49 69 60
From 1 to 9999 in steps of 1
[Courier Number (time-seconds)]
Dead time setting for three phase auto-reclose (2nd shot).
3P AR DT Shot 3 49 6A 60
From 1 to 9999 in steps of 1
[Courier Number (time-seconds)]
Dead time setting for three phase auto-reclose (3rd shot).
3P AR DT Shot 4 49 6B 60
From 1 to 9999 in steps of 1
[Courier Number (time-seconds)]
Dead time setting for three phase auto-reclose (4th shot).
Follower Time 49 6C 5
From 0.1 to 300 in steps of 0.01
[Courier Number (time-seconds)]
Time delay setting for follower CB reclosing after leader CB has reclosed.
SPAR ReclaimTime 49 6D 60
From 1 to 600 in steps of 1
[Courier Number (time-seconds)]
Reclaim time setting following single phase auto-reclosure.
3PAR ReclaimTime 49 6E 180
From 1 to 600 in steps of 1
[Courier Number (time-seconds)]
Reclaim time setting following three phase auto-reclosure.
