Adaptive Trip Faulted Circuit Indicator (up to 35kV)
-
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.
