Figure 82: Busbars divided by bus-section disconnectors (circuit breakers)
To derive the signals:
Signal
BB_DC_OP All disconnectors of this part of the busbar are open.
VP_BB_DC The switch status of all disconnectors on this part of the busbar are valid.
EXDU_BB No transmission error from any bay that contains the above information.
These signals from each double-breaker bay (DB_BUS) are needed:
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_DB 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.
The logic is identical to the double busbar configuration described in section
“Signals in single breaker arrangement”.

M15053-123 v4
The busbar earthing switch is only allowed to operate if all disconnectors of the
bus-section are open.
