13.4.1
Configuration guidelines
The following sections describe how the interlocking for a certain switchgear configuration can be
realized in the IED by using standard interlocking modules and their interconnections. They also
describe the configuration settings. The inputs for delivery specific conditions (Qx_EXy) are set to
1=TRUE if they are not used, except in the following cases:
•
989_EX2 and 989_EX4 in modules BH_LINE_A and BH_LINE_B
•
152_EX3 in module AB_TRAFO
when they are set to 0=FALSE.

Interlocking for line bay ABC_LINE (3)
13.4.2.1
Application
The interlocking for line bay (ABC_LINE, 3) function is used for a line connected to a double busbar
arrangement with a transfer busbar according to figure 124. The function can also be used for a
double busbar arrangement without transfer busbar or a single busbar arrangement with/without
transfer busbar.
