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 model Lodestar FM-CS is similar to model Lodestar FM, but it also has own easily mounted current sensors based on Rogowski coil that gives the following advantages:

• Current transformer does not have unnecessary load;
• It does not cause distortion when using a current transformer for measurements;
• It is used in substations where regular current transformers are not planned, installed or required.

Lodestar FM-CS model has:

• Different absolute and differentiated current thresholds;
• Other measurement accuracy;
• Communication protocol IEC 60870-5-104 is added.

Lodestar FM-CS benefits:

	Detects fault direction		Effective in resonant grounded neutral grids
	Logs all types of emergency situations: - phase-to-phase faults; - phase-to-ground faults; - 2-or-3-phase-to-ground faults		Operates in mixed systems: overhead, cable and overheadcable ones
	High accuracy in measurement of current and voltage		Above 0.1 A short circuit fault logging
	Immediate data processing in the Device		Operates in double-ended and loopfed grids, as well as in radial grids
	Feeder Monitor Lodestar FM-CS 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 clicks in SW		Memorizes more than 200 events
