Figure 161: 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

grounding switches of this section. DB_BUS_B (3) handles the circuit breaker QA2 that is

connected to busbar WA2 and the disconnectors and grounding switches of this section.

For a double circuit-breaker bay, the modules DB_BUS_A, DB_LINE and DB_BUS_B must be used.

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:

If, in this case, line voltage supervision is added, then rather than setting 989 to open state,

specify the state of the voltage supervision:

989_OP = VOLT_OFF

989_CL = VOLT_ON

If there is no voltage supervision, then set the corresponding inputs as follows:

VOLT_OFF = 1
