The Fisher Pierce
Series 1547 adaptive trip fault indicator indicates a fault
condition after sensing a rapid increase of fault current, followed
by a loss of load current. The innovative Adaptive Trip circuitry automatically
adjusts for changes in distribution feeder load currents from 1 to 800
amps.
The 1547 faulted circuit indicator is adaptable system-wide which eliminates trip selection
errors, load studies to determine FCI applications, and change-outs
due to load growth.
Display options
include flag, LED, or remote fiber optic display. The
inrush restraint function avoids false trips due to cold load pickup,
recloser operations, and other occurrences. Configurations are available
for both overhead and underground applications.
