Settings for Synchrophasors
Settings for Synchrophasors
The phasor measurement unit (PMU) settings are listed in Table I .1. Modify
these settings when you want to use the C37.118 synchrophasor protocol.
You must set Global enable setting EPMU to Y before the remaining SEL-751
synchrophasor settings are available. No synchrophasor data collection can
take place when EPMU := N.
You must make the serial port settings in Table I.5 or Ethernet port settings in
Table I.6 to transmit data with a synchrophasor protocol. It is possible to set
EPMU := Y without using any ports for synchrophasor protocols. For
example, the port MET PM ASCII command can still be used.
Certain settings in Table I.1 are hidden, depending on the status of other
settings. For example, if PHDATAI := NA, the ICOMP setting is hidden to
