outgoing feeders, which in turn results in tripping of all circuit breakers of the outgoing
feeders. For maximum safety, the protection relays can be configured to trip all the circuit
breakers regardless of where the arc is detected.

Figure 373:
Arc flash detector with several protection relays
Arc protection with several protection relays and a separate arc protection
system
When realizing an arc protection with both protection relays and a separate arc protection
system, the cable terminations of the outgoing feeders are protected by protection relays
using one lens sensor for each protection relay. The busbar and the incoming feeder are
protected by the sensor loop of the separate arc protection system. With arc detection at
