Figure 180: Circuit breaker failure protection function
Three arc protection ARCSARC1...3 stages are included as an optional function. The
arc protection offers individual function blocks for three arc sensors that can be
connected to the IED. Each arc protection function block has two different operation
modes, that is, with or without the phase and residual current check.
The operate signals from ARCSARC1...3 are connected to both trip logic TRPPTRC1
and TRPPTRC2. If the IED has been ordered with high speed binary outputs, the
individual operate signals from ARCSARC1...3 are connected to dedicated trip logic
TRPPTRC3...5. The output of TRPPTRC3...5 are available at high speed outputs
X110:HSO1, X110:HSO2 and X110:HSO3.
