Lodestar FM-CS

Feeder Monitors


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. Feeder Monitor Lodestar FM-CS monitors independently each input of switchgear cell with double cable input.
