4.2.6 Bus-section breaker
4.2.6.1 Signals from all feed-
ers
Interlocking
If there is no voltage supervision, then set the corresponding inputs as fol-
lows:
• VOLT_OP = 1
• VOLT_CL = 0
If the busbar is divided by bus-section circuit breakers into bus sections
and both circuit breaker are closed, the opening of the circuit breaker must
be blocked if a bus-coupler connection exists between busbar A and B on
one bus-section side and if on the other bus-section side a busbar transfer
is in progress:

Fig. 20 Busbars divided by bus-section circuit breakers
To derive the signals:
BBTR_OP
Signal if no busbar transfer is in progress concerning this bus section.
VP_BBTR
The switch status of BBTR is valid.
EXDUP_AB
Signal if there is no transmission error from any bay connected to the AB
busbars.
These signals from each line bay (ABC_LINE), each transformer bay
(ABC_TRAFO), and bus-coupler bay (ABC_BC) are needed:
Q1Q2OPTR
Signal if Q1 or Q2 or both are open.
VPQ1Q2TR
The switch status of Q1 and Q2 are valid.
