Lodestar FM-CS is a universal device for registration and analysis of fault processes in a network of any topology and neutral type. Lodestar FM-CS can be used as a logger, fault current indicator, high-voltage control device. It could be installed on the control board of relay compartment of a switchgear of any type on panels and control cabinets of relay equipment and on control boards of the substation.
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: 3 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.
