parameter setting OperMode. This shall be done taking into account the actual
location of the CT star point in this bay.
5. Connect the trip output from the BICPTRC_xx function block to the binary output
contact (alternatively tripping can also be arranged using GOOSE
communication). This will ensure proper tripping of the bus-section bay for any
relevant operation of the BBP including BFP tripping.
ACT configuration example for Bus-section bay is given in Figure 80.

Step 6: ACT engineering of the Bus Sectionalizing Disconnectors
Three bus-sectionalizing disconnectors are installed in this station. Each disconnector
is used to interconnect the two zones located at the two sections. Ultimately when this
type of disconnector is closed, the two relevant zones shall be merged (i.e. switched
into one common zone) in the IED software. In this particular station, the zones can be
possibly linked in the following way: Z1&Z4, Z2&Z5 and Z3&Z6. When any linking
shall occur, it depends on the operational status of the three bus-sectionalizing
disconnectors. More specifically, the following steps need to be done:
