Figure 28: 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.
