Faulted circuit indicator for overhead applications to locate distribution faults

The Fisher Pierce Series 1548 fault indicator is a single phase overhead device used to assist in locating distribution faults. The 1548 can be used for locating permanent or temporary fault events. Options are available to incorporate a low power, unlicensed transmitter for wireless fault indicator status.

When the faulted circuit indicator is activated by fault current, an encoded message is transmitted periodically to a hand held receiver. Remote Terminal Unit (RTU) receiver or Fisher Pierce SmartLink RTU.

Standard features include a replaceable lithium battery and improved C-Clamp hotstick mount with automatic torque limiting which guarantees proper mounting on conductors. The 1548 FCI incorporates choices of LED, radio, flag, or strobe light indication, fixed, inrush or adaptive trip circuit logic and both time and current reset options. The 1548 FCI is SmartLink™ ready for SCADA applications.
