Figure 97: Busbars divided by bus-section circuit breakers
To derive the signals:
Signal
BBTR_OP No busbar transfer is in progress concerning this bus-section.
VP_BBTR The switch status of BBTR is valid.
EXDU_12 No transmission error from any bay connected to busbar 1(A) and 2(B).
These signals from each line bay (ABC_LINE), each transformer bay
(AB_TRAFO), and bus-coupler bay (ABC_BC) are needed:
Signal
QB12OPTR QB1 or QB2 or both are open.
VPQB12TR The switch status of QB1 and QB2 are valid.
EXDU_12 No transmission error from the bay that contains the above information.
These signals from each bus-coupler bay (ABC_BC) are needed:
Signal
BC12OPTR No bus-coupler connection through the own bus-coupler between busbar WA1 and
WA2.
VPBC12TR The switch status of BC_12 is valid.
EXDU_BC No transmission error from the bay that contains the above information.
These signals from the bus-section circuit breaker bay (A1A2_BS, B1B2_BS) are
needed.
Signal
S1S2OPTR No bus-section coupler connection between bus-sections 1 and 2.
VPS1S2TR The switch status of bus-section coupler BS is valid.
EXDU_BS No transmission error from the bay that contains the above information.
For a bus-section circuit breaker between A1 and A2 section busbars, these
conditions are valid:
