Lodestar FM-CS2
Description
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.
Lodestar FM-CS2:
- Detects fault direction
- Effective in resonant grounded neutral grid
- Logs all types of emergency situation:
- phase-to-phase faults;
- phase -to-ground faults;
- 2-or-3-phase -to-ground faults - Operates in mixed networks: overhead, cable and overhead-cable ones
- High accuracy in measurement of current and voltage
- Up to 0.1 A short-circuit faults logging
- Immediate data processing in the Device
- Operates in double-ended and loop fed networks, as well as in radial networks
- Feeder Monitor Lodestar FM-CS2 displays a faulted phase on the front LED-display
- Event information both visually and in the SCADA system
- Easy to configure by a couple of clocks in SW
- Memorizes more than 200 events
Combines the functions of selective detection of all faulted lines and main power parameters measurement.
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.
