Figure 280: Directional overcurrent protection function
The upstream blocking from the start of the second low stage of three-phase
directional overcurrent protection DPHLPDOC2 is connected to the binary output
X110:SO1. This output can be used for sending a blocking signal to the relevant
overcurrent protection stage of the IED at the infeeding bay.
