If there is no second busbar B and therefore no

289 and 2089 disconnectors, then the

interlocking for 289 and 2089 are not used. The states for 289, 2089, 2189G, BC_12,

BBTR are set to open by setting the appropriate module inputs as follows. In the

functional block diagram, 0 and 1 are designated 0=FALSE and 1=TRUE:

• 289_OP = 1

• 289_CL = 0

• 2089_OP = 1

• 2089_CL = 0

• 2189G_OP = 1

• 2189G_CL = 0

• BC_12_CL = 0

• VP_BC_12 = 1

• BBTR_OP = 1

• VP_BBTR = 1

M13567-3 v7

The interlocking for transformer bay (AB_TRAFO, 3) function is used for a

transformer bay connected to a double busbar arrangement according to figure

140.

The function is used when there is no disconnector between circuit breaker and

transformer. Otherwise, the interlocking for line bay (ABC_LINE

, 3) function can be

used. This function can also be used in single busbar arrangements.
