Minimum dimensions – maximum functionality.
A Feeder Monitor Lodestar FM-CS2 can be used as a logger, fault current indicator, high-voltage control device. It is designed for switchgear cell with double cable output.
The functionality of the FM-CS / FM-CS2 models is similar to the Lodestar FM model, but these devices are designed for 6-36 kV distribution networks and feature:
- Easily mountable proprietary current sensors based on Rogowski coils: 6 sensors;
- IEC 60870-5-104 communication protocol;
- Device accuracy class 0.5
Rogowski Coil Benefits
- No additional CT burden.
- No measurement distortion.
- Perfect for substations without standard CTs.
Feeder Monitor Lodestar FM-CS2 monitors independently each input of switchgear cell with double cable input The Device in mounted in a switchgear cell or on a switchboard.
