SEL Synchrophasors
Settings
Settings
The phasor measurement control unit (PMCU) settings are listed in Table L.5 .
The Global enable setting EPMU must be set to Y before the remaining
SEL-351 synchrophasor settings are available. No synchrophasor data
collection can take place when EPMU = N. Use the serial port settings in
Table L.6 to transmit data using the SEL Fast Message Synchrophasor
protocol.
Certain settings in Table L.5 are hidden, depending on the status of other
settings. For example, if PHDATAV = V1, the PHDATAI setting is hidden to
limit the number of settings for your synchrophasor application.
