Fisher Pierce Adaptive Trip Faulted Circuit Indicator
The Fisher Pierce Adaptive TripTM
Series 1547 Faulted Circuit Indicator (FCI) revolutionizes fault indicator selection, application and operation.
The innovative Adaptive Trip circuitry automatically adjusts for changes in distribution feeder load currents from 1 to 800 amps.
The Adaptive Trip FCI indicates a fault condition after sensing a rapid increase of fault current, followed by a loss of load current. This logic circuitry more closely coordinates the Adaptive Trip FCI with distribution system protection devices.
Series 1547A (flag-type display) Adaptive Trip FCIs require the restoration of a minimum of load current to reset the indicator following a fault condition.
The minimum reset current must be present for the appropriate time interval for the flag to reset.
The inrush restraint function avoids false trips due to cold load pickup, recloser operations, etc. Inrush restraint is provided by a 40-85 seconds delay period after restoration of current.
