Lodestar FM CS

Description

Feeder monitors are solution for network parameters control and damaged section determination in overhead and underground lines. High-precision measurements and phasor measurements allow to monitor the power grid distribution network in real time. Fast fixation and localization of faults allows optimization of monitoring system and reducing blackout times.

Lodestar FM CS is a universal device for registration and analysis of fault processes in a network of any topology and neutral type. 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:

• Locates Phase to Ground faults in networks with all types of neutral;
• Events journal and waveform memory;
• Uses standard CT/CV;
• GPS time synchronisation;
• Embedded backup battery;
• Compact size.
