Appendix B -Settings and Signals
ORDINAL
831 VC< start
Phase C undervoltage level detector used in the pole dead logic. Detectors have a fixed threshold: undervoltage pickup 38.1 V-drop
off 43.8 V
832 VTS Fast Block
VT supervision fast block - blocks elements which would otherwise maloperate immediately a fuse failure event occurs
833 VTS Slow Block
VT supervision slow block - blocks elements which would otherwise maloperate some time after a fuse failure event occurs
834 CB1 Fail1 Trip
Bfail1 Trip 3ph
835 CB1 Fail2 Trip
Bfail2 Trip 3ph
836 CB2 Fail1 Trip
tBF1 trip 3Ph - three phase output from circuit breaker failure 2 logic, stage 1
837 CB2 Fail2 Trip
tBF2 trip 3Ph - three phase output from circuit breaker failure 2 logic, stage 2
838 Control TripCB1
Control trip - operator trip instruction to circuit breaker 1, via menu, or SCADA. (Does not operate for protection element trips)
839 Control CloseCB1
Control close command to circuit breaker 1. Operates for a manual close command (menu, SCADA), and additionally is driven by the
auto-reclose close command
840 Control TripCB2
Control trip - operator trip instruction to circuit breaker 2, via menu, or SCADA. (Does not operate for protection element trips)
841 Control CloseCB2
Control close command to circuit breaker 2. Operates for a manual close command (menu, SCADA), and additionally is driven by the
auto-reclose close command
842 CB1 Close inProg
Control Close in Progress
843 Block Main Prot
AR Block Main Protection. In P841 etc, there is no specific output DDB to block selected protection functions. If such a feature is
required for a particular application, appropriate mapping should be created in PSL, using output DDBs from sequence counter,
single phase dead time and three phase dead time logic as required.
844 CB1 AR 3p InProg
CB1 Auto Reclose/(AR 3 pole) in Progress
845 CB1 AR 1p InProg
CB1 AR 1pole in progress
846 Seq Counter = 0
Auto-reclose sequence counter is at zero - no previous faults have been cleared within recent history. The sequence count is at zero
because no reclaim times are timing out, and the auto-recloser is not locked out. The recloser is awaiting the first protection trip, and
all programmed cycles are free to follow
847 Seq Counter = 1
The first fault trip has happened in a new auto-reclose sequence. Dead time 1, or reclaim time 1 are in the process of timing out
848 Seq Counter = 2
Auto-reclose sequence counter is at 2. This means that the initial fault trip happened, and then another trip followed, moving the
counter on to 2
849 Seq Counter = 3
Auto-reclose sequence counter is at 3. This means that the initial fault trip happened, and then 2 trips followed, moving the counter
on to 3
850 Seq Counter = 4
Auto-reclose sequence counter is at 4. This means that the initial fault trip happened, and then 3 trips followed, moving the counter
on to 4
851 Seq Counter = 5
Seq Counter = 5 (In 2CB AR, there is no output specifically for seq counter = 5. However there is a DDB output for Seq Counter > 4.
may need a different allocation for DDB#851 in 2CB AR scheme.
852 CB1 Succ 3P AR
This signal is set when CB1 has successfully completed a three phase autoreclose cycle.
853 3P Dead Time IP
2CB logic provides separate output DDBs indicating (i) single phase dead time in progress, (ii) three phase dead time in progress (all
shots), (iii) 3 ph 1st shot dead time in progress, (iv) 3 ph 2nd shot dead time in progress, (v) 3 ph 3rd shot dead time in progress, (vi) 3 ph
4th shot dead time in progress.
