Lodestar FM-CS2

Lodestar FM

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.
