4.2.7.1 Signals in single
breaker arrangement
Interlocking
If there is no other busbar via the busbar loops that are possible, then
either the interlocking for the Q0 open circuit breaker is not used or the
state for BBTR is set to open. That is, no busbar transfer is in progress in
this bus section:
• BBTR_OP = 1
If the busbar is divided by bus-section disconnectors, the signal no other
disconnector connected to the bus section must be made by a project-spe-
cific logic.
The same type of module (A1A2_DC) is used for different busbars, that
is, for both bus-section disconnector A1A2_DC and B1B2_DC. But for
B1B2_DC, corresponding signals from busbar B are used.

Fig. 23 Busbars divided by bus-section disconnectors (circuit break-
ers)
To derive the signals:
A1DC_OP
Signal if all disconnectors on busbar A1 are open.
A2DC_OP
Signal if all disconnectors on busbar A2 are open.
VPA1_DC
The switch status of A1_DC is valid.
VPA2_DC
The switch status of A2_DC is valid.
EXDUP_BB
Signal if there is no transmission error from any bay that contains the
above information.
