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

Arc flash detector with several IEDs and a separate arc flash detector
system
When realizing an arc flash detector with both IEDs and a separate arc flash detector
system, the cable terminations of the outgoing feeders are protected by IEDs using one lens
sensor for each IED. The busbar and the incoming feeder are protected by the sensor loop
of the separate arc flash detector system. With arc detection at the cable terminations, an
IED trips the circuit breaker of the outgoing feeder. However, when detecting an arc on
the busbar, the separate arc flash detector system trips the circuit breaker of the incoming
