Figure 16: Overcurrent protection functions
The upstream blocking from the start of the instantaneous as well as the high stage
overcurrent protection function is connected to the binary output X110:SO1. This
output can be used to send a blocking signal to the relevant overcurrent protection
stage of the protection relay at the upstream bay.
