The Lodestar FM feeder monitor is a universal device for recording and analyzing fault events. It combines selective line fault detection in networks of any topology and neutral grounding type with the measurement of key power parameters on 6-230 kV overhead and cable lines of distribution networks using standard current transformers (CTs).
Benefits:
- High‑sensitivity earth fault recording – detects earth faults down to 0.5 A.
- Power system automation – automation functions for distribution networks.
- Non‑volatile memory – retains data and settings during power loss.
- Intelligent network monitoring – real‑time monitoring with advanced analytics.
- Faulted section visibility – clear fault location in any network topology and neutral grounding type.
- Universal sensor compatibility – standard CTs/VTs, dedicated CTs, capacitive voltage dividers.
- Flexible communication – relay output and RS‑485 (Modbus RTU) for SCADA integration.
