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

15.3.4.1 Application
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
252.
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.
