Signal
189OPTR
189 is open.
289OPTR
289 is open (AB_TRAFO, ABC_LINE)
22089OTR
289 and 2089 are open (ABC_BC)
789OPTR
789 is open.
VP189TR
The switch status of 189 is valid.
VP289TR
The switch status of 289 is valid.
V22089TR
The switch status of 289and 2089 is valid.
VP789TR
The switch status of 789 is valid.
EXDU_BB
No transmission error from the bay that contains the above information.
These signals from each bus-section disconnector bay (A1A2_DC) are also needed. For
B1B2_DC, corresponding signals from busbar B are used. The same type of module
(A1A2_DC) is used for different busbars, that is, for both bus-section disconnectors
A1A2_DC and B1B2_DC.
Signal
DCOPTR
The bus-section disconnector is open.
VPDCTR
The switch status of bus-section disconnector DC is valid.
EXDU_DC
No transmission error from the bay that contains the above information.
If no bus-section disconnector exists, the signal DCOPTR, VPDCTR and EXDU_DC are
set to 1 (TRUE).
If the busbar is divided by bus-section circuit breakers, the signals from the bus-section
coupler bay (A1A2_BS) rather than the bus-section disconnector bay (A1A2_DC) must
be used. For B1B2_BS, corresponding signals from busbar B are used. The same type of
module (A1A2_BS) is used for different busbars, that is, for both bus-section circuit
breakers A1A2_BS and B1B2_BS.
Signal
189OPTR
189 is open.
289OPTR
289 is open.
VP189TR
The switch status of 189 is valid.
VP289TR
The switch status of 289 is valid.
EXDU_BS
No transmission error from the bay BS (bus-section coupler bay) that contains the
above information.
For a busbar grounding switch, these conditions from the A1 busbar section are valid:
