These signals from each line bay (ABC_LINE), each transformer bay (AB_TRAFO), and each bus-
coupler bay (ABC_BC) are needed:
Signal
QB1OPTR
QB1 is open.
QB2OPTR
QB2 is open (AB_TRAFO, ABC_LINE)
QB220OTR
QB2 and QB20 are open (ABC_BC)
QB7OPTR
QB7 is open.
VPQB1TR
The switch status of QB1 is valid.
VPQB2TR
The switch status of QB2 is valid.
VQB220TR
The switch status of QB2and QB20 is valid.
VPQB7TR
The switch status of QB7 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
QB1OPTR
QB1 is open.
QB2OPTR
QB2 is open.
VPQB1TR
The switch status of QB1 is valid.
VPQB2TR
The switch status of QB2 is valid.
EXDU_BS
No transmission error from the bay BS (bus-section coupler bay) that contains
the above information.
For a busbar earthing switch, these conditions from the A1 busbar section are valid:
