Figure 119: Switchyard layout double circuit breaker
Three types of interlocking modules per double circuit breaker bay are defined.
DB_BUS_A (3) handles the circuit breaker QA1 that is connected to busbar WA1 and the
disconnectors and earthing switches of this section. DB_BUS_B (3) handles the circuit
breaker QA2 that is connected to busbar WA2 and the disconnectors and earthing
switches of this section.
For a double circuit-breaker bay, the modules DB_BUS_A, DB_LINE and DB_BUS_B
must be used.
10.4.9.2 Configuration setting
For application without 989 and 989G, just set the appropriate inputs to open state and
disregard the outputs. In the functional block diagram, 0 and 1 are designated 0=FALSE
and 1=TRUE:
• 989_OP = 1
• 989_CL = 0
• 989G_OP = 1
• 989G_CL = 0
