The FNET/GridEye system collects real-time synchrophasor data from over 300 FDR sensing units located across North America and around the world. It provides rich information about power system status including system frequency, relative phasor angle, ambient oscillation mode, etc. FNET/GridEye public website allows users to view frequency and angle data in table and map format and the data refreshes every four seconds.
