or if the disconnectors operate in parallel to other closed connections, or if they are
grounding on both sides.
• Circuit breaker closing is only interlocked against running disconnectors in its bay or
additionally in a transformer bay against the disconnectors and grounding switch on
the other side of the transformer, if there is no disconnector between CB and
transformer.
• Circuit breaker opening is only interlocked in a bus-coupler bay, if a bus bar transfer
is in progress.
To make the implementation of the interlocking function easier, a number of standardized
and tested software interlocking modules containing logic for the interlocking conditions
are available:
• Line for double and transfer busbars, ABC_LINE (3)
• Bus for double and transfer busbars, ABC_BC (3)
• Transformer bay for double busbars, AB_TRAFO (3)
• Bus-section breaker for double busbars, A1A2_BS (3)
• Bus-section disconnector for double busbars, A1A2_DC (3)
• Busbar grounding switch, BB_ES (3)
• Double CB Bay, DB_BUS_A(3), DB_LINE(3), DB_BUS_B(3)
• Breaker-and-a-half diameter, BH_LINE_A, BH_CONN, BH_LINE_B (3)
The interlocking conditions can be altered, to meet the customer specific requirements, by
adding configurable logic by means of the graphical configuration tool PCM600. The
inputs Qx_EXy on the interlocking modules are used to add these specific conditions.
The input signals EXDU_xx shall be set to true if there is no transmission error at the
transfer of information from other bays. Required signals with designations ending in TR
are intended for transfer to other bays.
