Measurement monitoring device Lodestar FM CS

for power distribution networkscompacthigh-precision

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
