Figure 17: Arc protection
Arc protection (ARCSARC1...3) is included as an optional function.
The arc protection offers individual function blocks for three arc sensors that can
be connected to the IED. The arc protection in this standard configuration detects
an arc flash and supplies the information for the operating arc protection unit,
which de-energizes the faulty area by opening the circuit breaker. It is possible to
use, for example, fast GOOSE communication to route the detected information to
the circuit breaker.
The alarm LED 10 is used as a common arc detected indication.
