ATRIY - Model Lodestar FM-CS - Feeder Monitor
odestar 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.
